maven-war-plugin overlay and m2e eclipse plugin - maven-3

I'm trying to leverage the useful overlay feature of the maven-war-plugin.
In other words, I have a template (packaged as WAR file, template-0.0.1.war) containing tag files, css, js and images.
When I set template-0.0.1.war as a dependency of the myApp project I get a final myApp.war containing all the files of template-0.0.1.war overwritten by those with the same path in the myApp project.
This is the behavior I want.
However, I need to introduce in the pom.xml of myApp a configuration of the maven-war-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<webResources>
<resource>
<directory>../path/to/another/dir</directory>
</resource>
</webResources>
</configuration>
</plugin>
As soon as I introduce such a configuration of the plugin, I obtain the final myApp.war with all the files from both template-0.0.1.war and myApp project but the files of template-0.0.1.war overwrite those with the same path in the myApp project.
This behavior is exactly the opposite of what I expect.
Can someone tell me where I'm wrong?
Thanks in advance.
Edit after the solution was found:
The described issue is due to the concurrency of different actions: the WAR overlay (which works correctly) and the external webResources.
In fact, the external webResources tag points to the template project directory: totally unuseful for Maven, but indispensable to "fool" the m2e eclipse plugin and let it see the custom tags contained in the template.
The solution I have adopted is to introduce 2 different profiles in the plugin section of my pom.xml: the first one called "eclipse" in which I inserted the maven-war-plugin with the webResources and a second profile (called "standard" and activated by default) without the maven-war-plugin.

From the maven war plugin documentation:
By default, the source of the project (a.k.a the current build) is added first (e.g. before any overlay is applied). The current build is defined as a special overlay with no groupId, artifactId. If overlays need to be applied first, simply configure the current build after those overlays.
If you have files in the template that are being overwritten by files in the child WAR, you may want to consider explicitly excluding them in the overlay configuration.
Here's what the documentation says to apply the overlay first:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<overlays>
<overlay>
<groupId>com.example.projects</groupId>
<artifactId>my-webapp</artifactId>
</overlay>
<overlay>
<!-- empty groupId/artifactId represents the current build -->
</overlay>
</overlays>
</configuration>
</plugin>
</plugins>

cargo-maven2-plugin:start fails with "Actually there are no valid types registered for this configuration", regardless of what containerId I enter

I'm trying to run integration tests with the cargo-maven2-plugin and Tomcat 8. I want the Maven build to start the container for me, so I have configured the start and stop goals as documented here. The problem is that regardless of what I enter as containerId, the start goal always fails with a message saying that there are no registered configurations. The error messages always ends in
Actually there are no valid types registered for this configuration. Maybe you've made a mistake spelling it?
I've tried various configurations, including ones that I found in various tutorials, and ones that user older Tomcat versions, but nothing helps. The error message is always the same.
Other posts here on Stack Overflow recommend to update the Cargo versions, but this doesn't apply to my problem: I already use the latest release version (1.6.5).
So, why do I keep getting this error?
For reference, here is one complete configuration that I tried out:
<plugin>
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven2-plugin</artifactId>
<version>1.6.5</version>
<executions>
<execution>

<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>stop-container</id>
<phase>post-integration-test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
<configuration>
<container>
<containerId>tomcat8x</containerId>

</artifactInstaller>
</container>
<configuration>
<type>standalone</type>
</configuration>
<deployables>
<!-- ... -->
</deployables>
</configuration>
</plugin>
The full error message for this configuration is:
[ERROR] Failed to execute goal org.codehaus.cargo:cargo-maven2-plugin:1.6.5:start (start-container) on project domain.db.itest: Execution start-container of goal org.codehaus.cargo:cargo-maven2-plugin:1.6.5:start failed: Cannot create configuration. There's no registered configuration for the parameters (container [id = [tomcat8x], type = [installed]], configuration type [standalone]). Actually there are no valid types registered for this configuration. Maybe you've made a mistake spelling it? -> [Help 1]
The solution was incredibly simple: I had the offline mode enabled. Without offline mode, Cargo downloaded the cargo-core-container-tomcat artifact, and apparently this artifact contains the definition of the tomcat8x configuration. Then, the container start was successful!
I had started the Maven build from Eclipse, so I didn't notice that the offline mode was enabled. I'm aware that this situation is quite special, but maybe someone else still benefits from my insight. It took me a while to solve, so I'm sharing problem and solution here. (After all, this is encouraged :-)
I got the key hint from a mailing list post, where thecargo-core-container-tomcat artifact was not downloaded due to a Nexus repository configuration.
This error is sometimes due to the cargo plugin version. Update your cargo plugin to the higher or latest version.
In my case, I updated from cargo 1.4.8 to cargo 1.7.0.

Jenkins:can not see test report tab

I can not see report tab here:
Public Junit test report:
I have configured Public JUnit test report, but I still can not see test report in left area.
As the OP joan.li adds in the comments, you need to make sure Your Jenkins installation knows about maven (as mentioned in "Jenkins executing maven from incorrect path"):
Add the default maven installation under (Jenkins -> configuration)
Goto the failing job and make sure you choose the default maven installation from dropdown
And You need to make sure your pom.xml does include a surefire build step
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.16</version>
<configuration>

</suiteXmlFiles>

Check if those xml files are generated

Generating multiple javadoc reports using maven-javadoc-plugin and Maven 3

We use a custom doclet to generate a report from custom javadoc tags, and use the Maven site plugin and javadoc plugin to generate both this report and the regular java API docs.
The section of the POM looks like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<reportSets>
<reportSet>
<id>html</id>
<reports>
<report>javadoc</report>
</reports>
</reportSet>
<reportSet>
<id>custom_report</id>
<configuration>
...
</configuration>
<reports>
<report>javadoc</report>
</reports>
</reportSet>
</reportSets>
</plugin>
Under Maven 2, this works fine, but in Maven 3 only one report is generated, that being the last one specified in the POM (confimed by swapping the reportSet elements).
After some experimenting I discovered that if I changed the regular report's goal from "javadoc" to "test-javadoc", then I got output from both report sets. So the problem seems to be that with Maven 3 I can't generate two reports that use the same javadoc-plugin goal.
Is this a bug, or is there some congifuration I've missed? I moved the maven-javadoc-plugin setup from reporting to the configuration of the site plugin as described at http://maven.apache.org/plugins/maven-site-plugin-3.0-beta-3/maven-3.html, to no avail. I'm using Maven 3.0.4, maven-site-plugin 3.0-beta-3 and maven-javadoc-plugin 2.8.1.
Thanks!
It's a bug in maven-reporting-exec component.
Report sets are kept in a map using the report goal as a key.

Get "Error: unable to resolve '/assets/images/**.png' for transcoding" while building on FlexMojos 4.0-RC2 and Flex SDK 4.5.1.21328

I get the this "Error: unable to resolve '/assets/images/**.png' for transcoding" while building on FlexMojos 4.0-RC2 and Flex SDK 4.5.1.21328. Code is like below
[Embed(source='/assets/images/lot_dimensions_bg_4digit.png')]
SDK version
<flex.sdk.version>4.5.1.21328</flex.sdk.version>
Flex Mojos version
<flex-mojos.version>4.0-beta-7</flex-mojos.version>
Thanks for any help.
You need to specifically add a dependency for flexmojos-threadlocaltoolkit-wrapper before
the compiler dependency.
See the following page for more details:
https://dev.c-ware.de/confluence/display/PUBLIC/Configuring+your+poms
I'm using the same version of the Flex SDK, but I'm using flexmojos 4.0-RC2. Embedded assets are working fine for me.
Make sure that when you build, you're copying the embedded assets over into target/classes. I had to include some special configuration for that.

Maven Antrun and Dependencies

(See edits below.)
The reason I can't just use the classpath, is because I need to manage some non-java libraries, and I'm compiling a non-java project.
I'm trying to use maven dependencies in an antrun call, following the documentation on the maven site:
http://maven.apache.org/plugins/maven-antrun-plugin/examples/classpaths.html
At the bottom of the page:
<property name="mvn.dependency.jar"
refid="maven.dependency.my.group.id:my.artifact.id:classifier:jar.path"/>
<echo message="My Dependency JAR-Path: ${mvn.dependency.jar}"/>
I can't make this work no matter how I try. I've tried ${} around the refid contents, I've tried colons, periods, etc.. as separators in every way I can think of.
Can anyone tell me what that refid should really look like for some common dependency?
EDIT:
Thanks for your reply.
Using your example SingleShot, I have the following:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<id>create-messages</id>
<phase>compile</phase>
<configuration>
<tasks>
<property name="build.compiler" value="extJavac"/>
<property name="compile_classpath" refid="maven.compile.classpath"/>
<property name="runtime_classpath" refid="maven.runtime.classpath"/>
<property name="test_classpath" refid="maven.test.classpath"/>
<property name="plugin_classpath" refid="maven.plugin.classpath"/>
<property name="log4j.jar" refid="log4j:log4j:jar"/>
<echo message="Where is the Log4J JAR?: ${log4j.jar}"/>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>
</dependencies>
</plugin>
And here's what I get when run mvn compile:

EDIT (2):
Looking at the sourcecode linked I decided to run "mvn -X compile" and grep for "Storing", which turns up a bunch of log output where things are getting stored.
Of interest are the facts that the dependency I'm explicitly specifying isn't showing in the list, and, that when I switch to a key based on one of the entries I do see, I still get the error.
Based on the code that SingleShot linked to, and random poking until it worked, here's how I got this problem "working", (I say in quotes because it feels very tenuous.)
Here's the way to make it properly work:
<property name="log4j_location"
value="${maven.dependency.log4j.log4j.jar.path}"/>
<echo message="${log4j_location}"/>
Some important things to note: You cannot use the maven dependency as a refid in setting the ant property. You have to use ${} to get the maven var value.
It appears that the dependency must be in the top-level dependency list, making log4j a dependency of the antrun plugin does not expose it to the plugin in anyway that I can see.
All of the path separators are dots (.), no colons (:) which is why I ultimately checked my own answer as correct.
Soapbox:
I would highly recommend anyone considering Maven use Ant with maven plugins or, even better, use Ant with Ivy instead.
This particular problem is a shining example of the utterly absurd level of difficulty associated with doing anything out of the norm with maven.
I say this having implemented an entire build system based on Maven2, and having also implemented several build systems in Ant. I've used both Maven2 and Ant with complex builds involving Java, Flex/AS3, C# and C++. Maven makes sense for Java projects that have no external dependencies on projects in other languages.
Maven does address some things that aren't addressed implicitly by Ant, but with some up front planning, Ant is the much more flexible, better documented, and the less buggy tool.
If you decide to go the ant route, make sure to define a structure for your projects, figure out your dependency system (Use one).
I think you will ultimately be much happier than with Maven, as you won't spend crunch time trying to fix your build system.
As an addendum to Aaron H.'s answer above, I had to set the plugin's version to 1.3 for that to actually work. I was using it without a specific version and was getting 1.1 (where nothing seems to work).
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.3</version>
...
</plugin>
Without an example of what you typed into your POM its hard to say, but consider a concrete example. Let's say your POM references log4j (groupId=log4j, artifactId=log4j). I believe this is how you would reference that JAR in your Ant file:
<property name="log4j.jar" refid="maven.dependency.log4j:log4j:jar.path"/>
<echo message="Where is the Log4J JAR?: ${log4j.jar}"/>
Ideally you shouldn't have to reference specific JARs, but rather, reference the entire classpath for the appropriate scope, as the somewhat sparse documentation for the plug-in indicates.
If you still have trouble, please post the <dependency> tag for a Maven POM dependency you are using and I can try to be more specific.
I looked at the plugin's code to confirm.
This works for me.
<copy file="${javax.mail:javax.mail-api:jar}" todir="tomcat/lib" />
<copy file="${org.springframework:spring-instrument-tomcat:jar}" todir="tomcat/lib" />
<copy file="${postgresql:postgresql:jar}" todir="tomcat/lib"/>
http://maven.apache.org/plugins/maven-antrun-plugin/examples/classpaths.html has the explanation of how to reference dependencies form the ant classpath.
There is a bug in the documentation. The path should be of the form:
<property name="mvn.dependency.jar"
value="${maven.dependency.my.group.id.my.artifact.id.classifier.jar.path}"/>
So the correct key for your log4j dependency would be:
maven.dependency.log4j.log4j.jar.path
Also note that it should be value= rather than refid=, so the full property would be:
<property name="log4j.jar"
value="${maven.dependency.log4j.log4j.jar.path}"/>
<echo message="My Dependency JAR-Path: ${log4j.jar}"/>
I have an existing ant and we planned to use (new) maven to call it. I encountered problems that I may not remember clear, but it is related to class pathes, maybe just like yours.
The problem is, the "ant" we are using daily is a shell script that sets class pathes, both on XNIX and Windows. I have not compared class pathes set by it and those available to maven, but my test showed they dont match and ant won't run with some pathes passed to it from maven.
What I am using is "exec-maven-plugin" and run ant as an external program with some arguments applied. This is sure to work but adds extra dependencies, though.
