Maven Return Codes

[Jörn Gebhardt <Jo...@ptv.de>]

Hi,

we have modularized our build by using Maven. However, because the build
runs into OutOfMemoryExceptions when we compile all modules within one Maven
Reactor call, we are using the reactor only to determine the build order and
call afterwards each module via the ant:exec call.

 <maven:reactor 
    basedir="${basedir}"
    includes="*/project.xml"
    ignoreFailures="false"
    collectOnly="true"
    postProcessing="true"/>
         
 <j:forEach var="reactorProject" items="${reactorProjects}">
    <ant:exec executable="cmd"  
        dir="${reactorProject.context.getVariable('basedir')}"
        failonerror="true">
      <arg line="/c maven"/>
    </ant:exec>
 </j:forEach>

Now we have the problem, that the build goes on even if one module fails. It
seems that the failonerror Ant property doesn't work correctly.
Does the maven.bat batch file return any error code that is passed on by the
cmd shell? Does anybody know, how we can make sure that our build fails if
one Maven call fails?

Thanks in advance,
Jörn

Hi,

The OutOfMemoryExceptions have been already discussed in previous threads.
Forking the jvm should help, also you can increase the memory available.
