how to use maven-compiler-plugin

[Pablo <pa...@tiger.com.pl>]

Hello everyone (this mail was sent to users@maven.apache.org but I 
didn't get clear answer)

I have the following project structure:
/src/webapp/WEB-INF/src etc.
/src/tests
/src/integration-tests

Junit tests are compiled automatically by setting the value below:
<testSourceDirectory>src/tests/java</testSourceDirectory>

Now I want to use the same plugin to compile integration-tests. The 
compiled tests should be placed in target/integration-tests.

Since fields:
private List compileSourceRoots;
private File outputDirectory;
are readonly it's not possible to set them in plugin's configuration.

I removed @readonly attribute and installed the plugin just to see if it 
would work.

This is the part of my pom.xml which defines compiler plugin:
     <plugin>
       <artifactId>maven-compiler-plugin</artifactId>
       <configuration>
         <encoding>iso-8859-2</encoding>
       </configuration>
       <executions>
         <execution>
           <id>testy</id>
           <phase>test-compile</phase>
           <goals>
             <goal>testCompile</goal>
           </goals>
           <configuration>
             <compileSourceRoots>
               <compileSourceRoot>src/integration-tests</compileSourceRoot>
             </compileSourceRoots>
             
<outputDirectory>${project.build}/integration-tests</outputDirectory>
           </configuration>
         </execution>
       </executions>
     </plugin>
I thought that I could change compilesourceRoot and outputDirectory and 
all integration tests would be compiled.
But it isn't so:

The compiler plugin is run twice. As you can see 
<outputDirectory>${project.build}/integration-tests</outputDirectory>
is used but test sources' directory is not. What am I doing wrong? How 
can I use this plugin to compile additional things? And will it be ever 
possible to do it? To make it work partially I had to remove @readonly 
attributes.

Thanks for reading
