i am not very familar with taskdef and classname... i am having trouble running an ant script from another ant script:
2011-05-25 15:50:26,040 [Thread-23] WARN ScriptRunner - BUILD FAILED
2011-05-25 15:50:26,040 [Thread-23] WARN ScriptRunner - C:\Work\6.70_Extensions\NightlyBuild\nightly_build.xml:31: The following error occurred while executing this line:

where line 6 is:

my root directory is C:\Work\6.70_Extensions\NightlyBuild and i have a folder C:\Work\6.70_Extensions\NightlyBuild\com\ANT_Tasks and i have a CFileEdit.java in that folder. Anybody knows what is wrong?
Edit:
I do not wish to change the structure of my ANT script, therefore what is the next step here?
i Complied my CFileEdit.java file into CFileEdit.class
I converted CFileEdit.class into CFileEdit.jar
i put this CFileEdit.jar into C:\apache-ant-1.8.2\lib where this is my ant directory?
please tell me if i am doing it right or wrong, i am having issues with this currently
You must compile the .java into a .class and use the class for classpath for the taskdef
Compile CFileEdit.java
Define taskdef as follows -
<taskdef name="CFileEdit" classname="com.ANT_Tasks.CFileEdit">
<classpath>
<!-- refer to the compiled class here along with others as necessary to execute the task -->
</classpath>
</taskdef>

I have the following build.xml solely to demonstrate the problem:
<project
xmlns:ivy="antlib:org.apache.ivy.ant"
name="test" default="test-ivy">
<target name="test-ivy">
<ivy:settings />
</target>
</project>
When invoking it with Ant (1.7.1) I get:
$ ant
Buildfile: build.xml
test-ivy:
BUILD FAILED
/home/voops/test/build.xml:7: Problem: failed to create task or type antlib:org.apache.ivy.ant:settings
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-/usr/share/ant/lib
-/home/voops/.ant/lib
-a directory added on the command line with the -lib argument
Total time: 0 seconds
However the Ivy jar does live in my ~/.ant/lib directory:
$ whoami
voops
$ls /home/voops/.ant/lib/ivy-2.3.0.jar
-rw-rw-r-- 1 voops voops 1222059 Nov 11 14:55 /home/voops/.ant/lib/ivy-2.3.0.jar
It appears that I have to manually indicate where the Ivy jar is located by adding the following element:
<taskdef uri="antlib:org.apache.ivy.ant" resource="org/apache/ivy/ant/antlib.xml" classpath="${user.home}/.ant/lib/ivy-2.3.0.jar"/>
... in my build.xml file. Once this element is added, the build succeeds.
Why is Ant not able to find Ivy even though the Ivy jar is located in the default ~/.ant/lib location and has to be explicitly told to look for it in the said location?
Update: It seems that the above element is only necessary for Ant 1.7.1. For Ant 1.8.2 or Ant 1.9.4, I don't have to add it.
It's due to the XML namespace declaration in the buildfile:
xmlns:ivy="antlib:org.apache.ivy.ant"
Since the prefix ivy: is being used, the uri attribute is needed in the taskdef task to allow calling the task with the prefix:
An example is shown in the typedef documentation:
uri: The uri that this definition should live in. since Ant 1.6
EDIT:
The antlib indicates that Ant by default can load the correct resource if the antlib is placed in the home directory of Ant:
When Ant encounters a element with a namespace URI with this pattern, it will check to see if there is a resource of the name antlib.xml in the package directory in the default classpath.
I would like to use 'ant-contrib', but I could not use it. I tried to use 3 way, without success.

I dont know other solution where I can iterate through a fileset/custom list doing something on them one by one. Thats why its important me.
Honestly, why there is no clear documentation ?
The problem was that YAN mentioned above. I have more ant in my system.
All in all, I removed them, a tried again my build xml with a brand new downloaded ant.
What is not on the PATH, and started from directory where it is.
I know this is not the best settings, but I could try it what I want, and solving the right setting is just question of time.
Thanks guys above your time and effort.
I'm running TeamCity 7 on Ubuntu 12, and I'm trying to deploy a war file to a tomcat server on machine with IP x using Ant.
The thing is - this worked on a different machine with TeamCity 7, and the only thing I've changed is the machine (moved to Ubuntu running on KVM), and the TC version (upgrade).
I've set ANT_HOME to the correct location, and I see the TC is using it in the build log:
... -Dant.home=/usr/share/ant ...
I've added the following jars to my ANT_HOME/lib:
catalina-ant, tomcat-coyote, tomcat-juli, tomcat-util
The build is running on an agent which has the default Ant settings
My ant file looks like this:
<target name="deploy.to.server">
<property name="port" value="${tomcat.port}"/>
<property name="tomcat.manager" value="manager/text"/>
<property name="url" value="http://${tomcat.server}:${port}/${tomcat.manager}"/>
<property name="path" value="/${server.name}"/>
<echo message="Deploying application to ${url}"/>
<antcall target="undeploy.from.tomcat"/>
<sleep seconds="3"/>
<antcall target="deploy.to.tomcat"/>
</target>
<taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask"/>
<taskdef name="undeploy" classname="org.apache.catalina.ant.UndeployTask"/>
<target name="deploy.to.tomcat" description="Install web application">
<deploy url="${url}" username="${username}" password="${password}"
path="${path}" war="${work.dir}/${path}.war"/>
</target>
<target name="undeploy.from.tomcat" description="Remove web application">
<undeploy url="${url}" username="${username}" password="${password}"
path="${path}"/>
</target>
I've got this in the TC log:

Now, this is extremely weird, as when I run this from the command line it works perfectly:
ant -buildfile deploy.xml -Dtomcat.server= ...
There is no apparent difference between the two - running it from the CL and through the TC agent should both be running Ant from ANT_HOME (usr/share/ant), and loading the libraries in $ANT_HOME/lib.
Any help would be appreciated.
:)
Thanks!
Just answering the question,
Thanks to #timomeinen - adding the catalina-ant.jar to $ANT_HOME/lib did the job.
That means it is not seeing the lib catalina-ant.jar
You can add:
classname="org.apache.catalina.ant.DeployTask"
classpath="C:\Programming\Tomcat\Instances\8080\lib\catalina-ant.jar"
It will solve this reference problem, but I guess you will face similar problems in the future with other libraries, so in the long term you will still need solve the reference problem.
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:

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.
