[Maven-plugins-cvs] Changing classpath for test goal

[Elliotte H. <el...@me...>]

I'm trying to get the Maven plugin for Cobertura to work. Cobertura 
instruments code to measure coverage of the test suite. To do this it 
recompiles the code base into a different directory from the usual build 
directory. I then need to run the test suite (<attainGoal 
name="test:test"/>)  using this instrumented directory rather than the 
usual build directory.

Using verbose output from Maven it's apparent that the tests are running 
with the original code rather than the instrumented code:

     [junit] [DEBUG] Execute:Java13CommandLauncher: Executing
'/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Home/bin/java'
with arguments:
'-Dbasedir=/Users/elharo/Projects/Jaxen'
'-classpath'
'/Users/elharo/Projects/Jaxen/target/test-classes:/Users/elharo/Projects/Jaxen/target/classes:/Users/elharo/.maven/repository/dom4j/jars/dom4j-1.6.1.jar:/Users/elharo/.maven/repository/jdom/jars/jdom-1.0.jar:/Users/elharo/.maven/repository/xerces/jars/xmlParserAPIs-2.6.2.jar:/Users/elharo/.maven/repository/xerces/jars/xercesImpl-2.6.2.jar:/Users/elharo/.maven/repository/xom/jars/xom-1.0b3.jar:/Users/elharo/.maven/repository/urbanophile/jars/java-getopt-1.0.9.jar:/Users/elharo/.maven/repository/javancss/jars/javancss-21.41.jar:/Users/elharo/.maven/repository/javancss/jars/ccl-21.41.jar:/Users/elharo/.maven/repository/asm/jars/asm-2.0.jar:/Users/elharo/.maven/repository/oro/jars/oro-2.0.8.jar:/Users/elharo/.maven/repository/log4j/jars/log4j-1.2.8.jar:/Users/elharo/.maven/repository/cobertura/jars/cobertura-1.6.jar:/Users/elharo/.maven/repository/junit/jars/junit-3.8.1.jar:/Users/elharo/.maven/repository/xml-apis/jars/xml-apis-1.0.b2.jar:/Users/elharo/.maven/repository/xerces/ja

rs/xerces-2.4.0.jar:/opt/maven-1.0.2/lib/ant-1.5.3-1.jar:/opt/maven-1.0.2/lib/ant-optional-1.5.3-1.jar'
'org.apache.tools.ant.taskdefs.optional.junit.JUnitTestRunner'

Instead of /Users/elharo/Projects/Jaxen/target/classes that should be
/Users/elharo/Projects/Jaxen/target/cobertura/classes

What I'm not sure of is how to change the Cobertura plugin.jelly file to 
use a
different directory for the test classpath. Currently we have this:

           <attainGoal name="cobertura:on"/>
           <attainGoal name="test:test"/>


The cobertura:on goal does set the following variables:

      <maven:set plugin="maven-java-plugin" property="maven.build.dest" 
value="${instrumented}"/>
       <maven:set plugin="maven-test-plugin" property="maven.build.dest" 
value="${instrumented}"/>

$instrumented is the directory where the instrumented classes live) and 
I've verified via log:info that these variables do get changed. However, 
this doesn't seem to affect the classpath for the JUnit test runner.


Any ideas?
