[jira] [Commented] (MNG-5601) multimodule plugin configuration e.g. "build-tools" pattern broken

["Matt Benson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MNG-5601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15055042#comment-15055042 ] 

Matt Benson commented on MNG-5601:
----------------------------------

Original prescription is:
{code}
./pom.xml references build-tools, setting for child projects
build-tools/pom.xml parent ..
module1/pom.xml parent ..
module2/pom.xml parent ..
etc.
{code}

To work around:
{code}
./pom.xml
build-tools/pom.xml parent ..
parent/pom.xml parent .. references build-tools, setting for child projects
module1/pom.xml parent ../parent
module2/pom.xml parent ../parent
etc.
{code}

> The recommendation at https://maven.apache.org/plugins/maven-checkstyle-plugin/examples/multi-module-config.html breaks down in projects that use the pattern more than once, e.g. for checkstyle/findbugs/PMD alike. I have boiled this down to a super-simple test project that defines a build-tools module, and in separate profiles declares each of these plugins with a dependency on that submodule. Activating any one of these profiles and calling `mvn validate` works fine, but as soon as you activate two or more of them the command fails with "The projects in the reactor contain a cyclic reference".
