 not sure the unified source directory structure addresses this issue.

 Properties

 maven.user.config.dir (system,default=${user.home}/.m2)
 maven.home            (system,user,default=${user.home}/m2)
 maven.repo.local      (system,user,default=${maven.user.config.dir}/repository)

 We need to define what happens in the when things are not setup correctly

            String jdkName = jenkinsEnv.jdkFromVersion(buildOs, buildJdk)
            String mvnName = jenkinsEnv.mvnFromVersion(buildOs, buildMvn)
            try {
                withEnv(["JAVA_HOME=${ tool "$jdkName" }",
                         "PATH+MAVEN=${ tool "$jdkName" }/bin:${tool "$mvnName"}/bin",
                         "MAVEN_OPTS=-Xms2g -Xmx4g -Djava.awt.headless=true"]) {
