thanks ossi my problem is not that checkstyle doesn't find the configuration. i have my configuration in a dependency in a jar in my repository. it is found and simple submodules are checkstyled fine.
it's just that checkstyle does not find dependencies on submodules in the same project. it is only resolving dependencies that are in the repository, not the ones that are in the current project. when i copy the example from http://maven.apache.org/plugins/maven-checkstyle-plugin/examples/multi-module-config.html checkstyle does not even find the checkstyle.xml configuration, as it can not resolve the dependency in the same project and only searches for the build-tools module in the repository. here is what happens: $ mvn checkstyle:checkstyle [INFO] Scanning for projects... [INFO] Reactor build order: [INFO] WhizBang Parent [INFO] Unnamed - com.example.whizbang:build-tools:jar:1.0 [INFO] Unnamed - com.example.whizbang:subProj1:jar:1.0 [INFO] Unnamed - com.example.whizbang:subProj2:jar:1.0 [INFO] Searching repository for plugin with prefix: 'checkstyle'.

Then, install it using the command: mvn install:install-file -DgroupId=com.example.whizbang -DartifactId=build-tools -Dversion=1.0 -Dpackaging=jar -Dfile=/path/to/file Alternatively, if you host your own repository you can deploy the file there: mvn deploy:deploy-file -DgroupId=com.example.whizbang -DartifactId=build-tools -Dversion=1.0 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id] Path to dependency: 1) org.apache.maven.plugins:maven-checkstyle-plugin:maven-plugin:2.2 2) com.example.whizbang:build-tools:jar:1.0 ---------- 1 required artifact is missing. for artifact: org.apache.maven.plugins:maven-checkstyle-plugin:maven-plugin:2.2 from the specified remote repositories: apache.snapshots (http://people.apache.org/repo/m2-snapshot-repository), central (http://repo1.maven.org/maven2) [INFO] ------------------------------------------------------------------------ [INFO] For more information, run Maven with the -e switch [INFO] ------------------------------------------------------------------------ [INFO] Total time: 1 second [INFO] Finished at: Sat Feb 07 10:49:39 CET 2009 [INFO] Final Memory: 7M/80M [INFO] ------------------------------------------------------------------------ so now checkstyle does not even find the submodule that holds the config. again "mvn test" runs without problems. when i leave out the custom checkstyle config and run checkstyle with the default configuration the same error appears. subProj2 depends on subProj2 -> checkstyle tries to download subProj1 from rep -> fails.. here the output: $ mvn checkstyle:checkstyle [INFO] Scanning for projects...
