I use a ant tast called listtopath
This is part of:
http://snapshots.repository.codehaus.org/org/codehaus/mojo/was-plugin-anttasks/1.0/
This task is to get around the headache of trying to get
${maven.compile.classpath} to be passed from maven to the ant mojo.
It has worked like a treat in Maven 2 (I've included the maven 2 example)
but trying to run on maven 3 the CP isn't being passed through.
Basically this is what I do:
I have a simple mojo that takes a reference to the maven project.
It then uses the listtopath task to convert it into a refid that can be used.
eg.
The mojo.
the parameter to pass the maven project
<pluginMetadata>
<mojos>
<mojo>
<goal>ejb-stub-compile</goal>
<call>ejb-stub-compile</call>
<requiresProject>true</requiresProject>
<!--- rest ommitted --//>
<parameter>
<name>mavenproject</name>
<type>org.apache.maven.project.MavenProject</type>
<required>true</required>
<description>This is the pom for the project. Property is
read-only (i.e you can not set it)
</description>
</parameter>
<!--- rest ommitted --//>
Then in my maven-ant build
<project xmlns:artifact="antlib:org.apache.maven.artifact.ant">
<property environment="env" value=""/>
<!-- make reference to the listtopath -->
<taskdef name="listtopath"
classname="org.codehaus.mojo.wasanttasks.ListToPathTask">
<classpath>
<pathelement
location="${env.USERPROFILE}/.m2/repository/org/codehaus/mojo/was-plugin-anttasks/1.0/was-plugin-anttasks-1.0.jar"/>
</classpath>
</taskdef>
<target name="ejb-stub-compile" depends="init-windows,init-unix">
<echo>Starting ejb stub compilation</echo>
<!-- using the maven project get the classpath -->
<listtopath targetRef="classpath" mavenproject="mavenproject"/>
<!-- convert it into a path and store in ref -->
<pathconvert property="converted.compile.classpath" refid="classpath"
dirsep="/"/>
<!-- if the classpath works it should appear here -->
<echo>classpath:${converted.compile.classpath}</echo>
After compiling this I make a local-repository reference and call it
the call in the pom.
<plugin>
<groupId>com.nag.build</groupId>
<artifactId>ejb-stub-compile</artifactId>
<version>1.0.15</version>
<configuration>
<mavenproject
implementation="org.apache.maven.project.MavenProject">${project}</mavenproject>
<websphere.home>${websphere.home}</websphere.home>
<input-file>${project.build.directory}/${project.build.finalName}.jar</input-file>
<output-file>${project.build.directory}/${project.build.finalName}-tmp.jar</output-file>
</configuration>
<executions>
<execution>
<phase>pre-integration-test</phase>
<goals>
<goal>ejb-stub-compile</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.codehaus.mojo</groupId>
<artifactId>was-plugin-anttasks</artifactId>
<version>1.0</version>
</dependency>
</dependencies>
</plugin>
The above worked with maven2 - migrating to Maven3 has caused the listtopath to
stop working.
Alternatively there has to be an easier way to pass the cp through to ant!!!!
