      Description

      In a multimodule (>120 modules) maven build, the compiler plug-in would seem to fail in creating a correct class-path every now and then.

      Instead of this entry in maven -X logs for a single module build:

      [DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile' with basic configurator -->
      ..
      [DEBUG]   (f) classpathElements = [/home/karniemi/"mymodulepath"/target/classes, /home/karniemi/.m2/repository/org/apache/servicemix/servicemix-utils/1.2.0/servicemix-utils-1.2.0.jar, /home/karniemi/.m2/repository/org/apache/geronimo/specs/geronimo-stax-api_1.0_spec/1.0.1/geronimo-stax-api_1.0_spec-1.0.1.jar, /home/karniemi/.m2/repository/org/codehaus/woodstox/wstx-asl/3.2.6/wstx-asl-3.2.6.jar, /home/karniemi/.m2/repository/org/apache/servicemix/specs/org.apache.servicemix.specs.jbi-api-1.0/1.4.0/org.apache.servicemix.specs.jbi-api-1.0-1.4.0.jar, /home/karniemi/.m2/repository/org/apache/geronimo/specs/geronimo-activation_1.1_spec/1.0.2/geronimo-activation_1.1_spec-1.0.2.jar, /home/karniemi/.m2/repository/log4j/log4j/1.2.14/log4j-1.2.14.jar]
      

      every now and then I get this in the parallel build:

      [DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile' with basic configurator -->
      ...
      [DEBUG]   (f) classpathElements = [/home/karniemi/"mymodulepath"/target/classes]
      

      And of course the compilation fails because none of the dependencies are added to the classpath. Sometimes it goes fine in the multi-module build, but every now and then it fails for this.

      In both maven runs I can see that the dependencies are resolved fine:

      [DEBUG] "mymodule":jar:DYNAMIC-SNAPSHOT
      [DEBUG]    junit:junit:jar:4.7:test
      [DEBUG]    org.apache.servicemix:servicemix-utils:jar:1.2.0:provided
      [DEBUG]       org.apache.geronimo.specs:geronimo-stax-api_1.0_spec:jar:1.0.1:provided
      [DEBUG]       org.codehaus.woodstox:wstx-asl:jar:3.2.6:provided
      [DEBUG]       org.apache.servicemix.specs:org.apache.servicemix.specs.jbi-api-1.0:jar:1.4.0:provided (scope managed from compile) (version managed from 1.1.0)
      [DEBUG]          org.apache.geronimo.specs:geronimo-activation_1.1_spec:jar:1.0.2:provided
      [DEBUG]    log4j:log4j:jar:1.2.14:provided
      

      The pluginArtifactMap looks like this:

      [DEBUG]   (s) pluginArtifactMap = {org.apache.maven.plugins:maven-surefire-plugin=org.apache.maven.plugins:maven-surefire-plugin:maven-plugin:2.6:, org.apache.maven.surefire:surefire-booter=org.apache.maven.surefire:surefire-booter:jar:2.6:compile, org.apache.maven.surefire:surefire-api=org.apache.maven.surefire:surefire-api:jar:2.6:compile, org.apache.maven.surefire:maven-surefire-common=org.apache.maven.surefire:maven-surefire-common:jar:2.6:compile, org.apache.maven.shared:maven-common-artifact-filters=org.apache.maven.shared:maven-common-artifact-filters:jar:1.2:compile, org.codehaus.plexus:plexus-utils=org.codehaus.plexus:plexus-utils:jar:2.0.5:compile, junit:junit=junit:junit:jar:3.8.1:compile, org.apache.maven.reporting:maven-reporting-api=org.apache.maven.reporting:maven-reporting-api:jar:2.0.9:compile}
      

      I'm really using jbi-maven-plugin for most of the modules, and that plugin binds the other plugins -also the compiler-plugin -to maven life-cycle phases.
