I am trying to use ojdeploy to compile and build an ADF application through an AntTask.
The ojdeploy task works fine when I specify not to compile the project by adding the line
The ojdeploy task is unable to find several jars required to build the application which I have specified.
I can't find any documentation which describe the use of the ojdeploy to compile applications which makes me think that it does not work.
The ant task I have is below. My thoughts are that the ojdeploy task does not have the jars required to build the project on its classpath. I can't see a way to add these jars to the classpath however.
ojdeploy task:
<target name="deploy" description="Deploy JDeveloper profiles">
<property name="status" value="${env.WORKSPACE}/deploy/ojdeploy-statuslog.xml"/>
<taskdef name="ojdeploy"
classname="oracle.jdeveloper.deploy.ant.OJDeployAntTask"
uri="oraclelib:OJDeployAntTask"
classpathref="classpath"/>
<ora:ojdeploy xmlns:ora="oraclelib:OJDeployAntTask"
executable="${env.oracle.middleware}/jdeveloper/jdev/bin/ojdeploy.exe"
failonerror="true"
ora:buildscript="${env.WORKSPACE}/deploy/ojdeploy-build.xml"
ora:statuslog="C:/Oracle/Middleware/ojdeploy-statuslog.xml">
<ora:deploy>
<ora:parameter name="workspace"
value="${env.WORKSPACE}/JWS.jws"/>
<ora:parameter name="profile"
value="*"/>
<!--<ora:parameter name="nocompile" value="true"/>-->
<ora:parameter name="outputfile"
value="${env.WORKSPACE}/deploy/${deployment.profile.name}"/>
</ora:deploy>
</ora:ojdeploy>
</target>
Resolved.
ojdeploy uses the jws and jpr files to find the libraries required. The jpr file was missing several JDeveloper/ADF libraries which JDeveloper is able to resolve.
However for ojdeploy to work ALL the libraries and dependencies are required to be in the jws/jpr file accordingly using the libraries/classpath and dependencies options.

I'm trying to create an OSGi wrapper for the newest version of jTDS. I'm trying to add the wrapping process to the existing jTDS build process (Ant-based). I've downloaded the latest bnd.jar and added the following to the jTDS build.xml:
<taskdef resource="aQute/bnd/ant/taskdef.properties" classpath="bnd.jar"/>
<bndwrap trace="true" definitions="${basedir}/bnd" output="${build}/${ant.project.name}-${version}.osgi.jar">
<fileset dir="${build}" includes="*.jar"/>
</bndwrap>
I've also got a very simple bnd definition defined:
version=1.2.6
Export-Package: net.sourceforge.jtds*;version=${version}
Bundle-Version: ${version}
Bundle-Name: net.sourceforge.jtds
When I execute the dist task in Ant, it should be creating a JAR with the proper OSGi manifest. It IS creating another JAR, but the manifest is identical to the original.
If I execute the same wrap directly against the bnd JAR:
java -jar bnd.jar wrap -p bnd\jtds-1.2.6.bnd -o build\jtds-1.2.6.osgi.jar build\jtds-1.2.6.jar
I get the correct OSGi manifest.
What is going wrong during the Ant build?
It seems to be a problem with the latest version of bnd, found here. The Ant WrapTask was retooled some and just doesn't seem to work (maybe it's just misconfigured; documentation hasn't kept up with code).
I dropped in version 1.50.0 instead and everything worked as expected both through the bnd.jar and through Ant.
I am trying to run an Ant task from within IBM RSA IDE using Ant build ...
I get the following error message:
BUILD FAILED
build.xml:21: Could
not create task or type of type: getProjectData.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'getProjectData'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
task and make sure it contains more than merely a META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
- You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.
Here's the Ant buildfile:
<!-- Get property locationName. -->
<target name="config">
<echo message="${ear.project.name}" />
<getProjectData projectName="${ear.project.name}" />
</target>
I am not quite sure what the problem is here because the error message seems not helpful. Any suggestions?
I believe getProjectData is an IBM extension to ant. Like you, I had a similar error, but I was able to get it working after ensuring the Run in the same JRE as the workspace option was enabled (which you can find by right-clicking the build file, run-as, Ant Build..., and selecting the option on the JRE tab).
I discovered the solution on the IBM info center:
The Run in the same JRE as the workspace option enables the classpath
of the workbench to access the additional Ant tasks that perform
operations that are specific to the workbench, such as projectImport,
projectBuild, workspaceBuild, ejbDeploy, or earExport. If your Ant
build script uses any Ant tasks that perform workbench operations,
verify that you selected the Run in the same JRE as the workspace
option; otherwise you might get the following error message in the
Console view:
Problem: failed to create task or type <Ant task> Cause:
The name is undefined.
The build file I used looked like this:
<?xml version="1.0"?>
<project name="Test" default="config" basedir=".">
<target name="config">
<getProjectData Basedir="${basedir}" />
<echo message="getProjectData: projectName=${projectName}
nature=${natureName}
workspace=${workspaceName}
basedir=${basedir}" />
</target>
</project>
And output:
Buildfile: C:\DATA\java\workspace\test-java\build.xml
config:
[getProjectData] Setting projectName=test-java
[getProjectData] Retrieved following Project Data :
[getProjectData] workspaceName=C:\DATA\java\workspace

I want to get the set of runtime dependencies from maven in ant. I'm using the maven ant tasks.
I know that you can limit the dependencies by scope (see docs):
<artifact:dependencies filesetId="dependency.fileset" useScope="runtime">
<artifact:pom file="pom.xml" id="myProject" />
</artifact:dependencies>
and that the scope options (from the docs) are:
•compile - Includes scopes compile, system and provided
•runtime - Includes scopes compile and runtime
•test - Includes scopes system, provided, compile, runtime and test
However, I want to get only the runtime dependencies (i.e. exclude compile dependencies). My best idea so far is to get the runtime dependencies and the compile dependencies, and iterate through the runtime dependencies to find those that are not in the compile dependencies, but I haven't yet worked out how to do this.
Any ideas?
You need something along the lines of:
...
<artifact:pom id="maven.project" file="pom.xml"/>
<artifact:dependencies useScope="runtime"
filesetId="dependencies.runtime"
pomRefId="maven.project"
settingsFile="${settings.xml}"/>
...
Then you can use the dependencies.runtime fileset as usual.
I hope this makes more sense.
So this what I tried to get the difference of the runtime and compile file sets (although this makes the assumption that there's nothing in the compile fileset that's not also in the runtime fileset)
<artifact:dependencies filesetId="runtime" scopes="runtime">
<artifact:pom file="pom.xml" id="myProject" />
</artifact:dependencies>
<artifact:dependencies filesetId="compile" scopes="compile">
<artifact:pom file="pom.xml" id="myProject" />
</artifact:dependencies>
<difference id="difference" >
<resources refid="runtime" />
<resources refid="compile" />
</difference>
However, this wasn't producing the results that I expected, so I did the following, and found that the runtime fileset did not contain the compile dependencies.
<echo message="${toString:runtime}" />
<echo message="${toString:compile}" />
So I can just use the runtime scope...
I'm in the process of modifying an Ant script (currently in use from within MyEclipse) to work from the command line. I'm doing this so anyone can check out the project and build it without MyEclipse. The problem I'm running into is that MyEclipse includes the dependencies behind the scenes. It does this by looking at the workspace's Ant configuration and compiling the classpath based on the selected libraries in the preferences dialog. Long story short, I need to take those dependencies and make the script smart enough to include them on its own, without the help of MyEclipse.
The tasks that are giving me a headache are the sshexec and scp tasks. They are optional ant tasks that require a version of jsch to run. I removed jsch from MyEclipse's Ant classpath and added it to a lib folder in the project itself (lib/dev). MyEclipse immediately complained that the SSHExec class could not find the dependent class, com.jcraft.jsch.UserInfo which is part of jsch-0.1.44.jar.
I don't see a way to set the classpath for Ant from within the build script. I have the following code, which adds a path element to the script, but I don't think Ant uses this unless explicitly associated to a task or another element.
<path id="web-jars">
<fileset dir="${web-lib}">
<include name="**/*.jar" />
</fileset>
<fileset dir="${app-lib}"> <!-- this is where jsch resides -->
<include name="**/*.jar" />
</fileset>
</path>
It seems that I need to use taskdef to define the sshexec and scp tasks:
<taskdef name="sshexec" classname="org.apache.tools.ant.taskdefs.optional.ssh.SSHExec"
classpathref="web-jars"/>
MyEclipse complains about this, "taskdef A class needed by class org.apache.tools.ant.taskdefs.optional.ssh.SSHExec cannot be found: com/jcraft/jsch/UserInfo"
It's clearly in the classpathref, web-jars. And I can't run anything in the script because of this malformed or misconfigured taskdef.
The problem here is that the SSHExec class is loaded from a classloader which itself has no access to your web-jars class loader. Supplying this classpath for the taskdef does not change this. Each class can only load classes from its own classloader and any parent class loaders, but the web-jars classloader is not a parent class loader of SSHExec's class loader (it is likely the other way around, since SSHExec seems to be found here).
It looks like this:
ClassLoader web-jars -------------> application CL -------------> bootstrap CL
taskdef
=> look for SSHExec here
=> look first in parent class loader
=> look for SSHExec here
=> look first in parent class loader
=> look for SSHExec here
=> not found
=> look in our own classpath
=> found, load the class
=> it somehow uses interface UserInfo
=> look for UserInfo here
=> look first in parent class loader
=> look for UserInfo here
=> not found
=> look in our own classpath
=> not found, throw exception.
The VM has no idea to look for UserInfo (and the other JSch classes) in the web-jars classloader.
I suppose the SSHExec task is somewhere in the usual ant classpath, i.e. loaded by the application class loader. Then removing SSHExec from ant's classpath (or adding jsch.jar to it) seems to be the only solution here.
Create ~/.ant/lib and copy jsch.jar in there as part of the build initialisation. Any tasks which do scp/sshexec work should depend on this init target.
<target name="init">
<property name="user.ant.lib" location="${user.home}/.ant/lib"/>
<mkdir dir="${user.ant.lib}"/>
<copy todir="${user.ant.lib}">
<fileset dir="${basedir}/build/tools" includes="jsch-*.jar"/>
</copy>
</target>
<target name="mytarget" depends="init">
<scp todir="user#host"><fileset dir="..."/></scp>
</target>
The Ant within Eclipse unfortunately won't pick this up immediately as it does not read ~/.ant/lib on every execution; After running mytarget within Eclipse once and watching it fail, then go to:
Window>Preferences>Ant>Runtime and press Restore Defaults - this will add any .jar files from ~/.ant/lib to the Global Entries section and you should be good to go.
I have a build script and as part of that script it copies a jar file to a directory, for ease lets call it the utils jar. the utils jar is built by another build script sitting in another directory. What im trying to do have my build script run the utils build script so that I can ensure the utils jar is up to date.
So I know I need to import the utils build file.
<import file="../utils/build/build.xml" />
Which doesn't work because the import task, unlike almost every other ant taks, doesn't run from basedir, it runs from the pwd. So to get around that I have this little ditty, which does successfully import the build file
<property name="baseDirUpOne" location=".." />
<import file="${baseDirUpOne}/utils/build/build.xml" />
So now that ive solved my import problem I need to call the task, well that should be easy right:
<antcall target="utils.package" />
note that in the above, utils is the project name of ../utils/build/build.xml
the problem I'm now running into is that ant call doesn't execute in ../utils/build so what I need, and cant find, is a runat property or something similar, essentially:
<antcall target="utils.package" runat="../utils/build" />
The reason I need this is that in my utils build file the step to select which code to copy to the jar is based on relative paths so as to avoid hardcoding paths in my ant file. Any ideas?
I've got something similar set up: I have a main Ant build.xml which calls a separate build.xml that takes care of building my tests. This is how I do it:
<target name="build-tests">
<subant target="build">
<fileset dir="${test.home}" includes="build.xml"/>
</subant>
</target>
The trick is to use subant instead of antcall. You don't have to import the other build file.
Try using the "ant" task instead of the "antcall" task, which runs the imported build directly instead of importing it into the current build file. It has a "dir" parameter:
the directory to use as a basedir
for the new Ant project. Defaults to
the current project's basedir, unless
inheritall has been set to false, in
which case it doesn't have a default
value. This will override the basedir
setting of the called project.
So you could do:
<ant antfile="${baseDirUpOne}/utils/build/build.xml" dir="../utils/build" />
or something like that.
You can pass params down to antcall using nested in the antcall block. So, you can pass the properties down that way (probably even basedir since properties are immutable).
