MavenEmbedderUtils#getMavenVersion() leaks file descriptors

    XMLWordPrintable

Details

    Description

      Maven Plugin and Artifactory Plugin are affected.

      Such descriptor leaks, for example, prevent change of the Maven tool version on Windows.

      The fix is required here: https://github.com/jenkinsci/lib-jenkins-maven-embedder/blob/master/src/main/java/hudson/maven/MavenEmbedderUtils.java#L186-L213 . This library is included directly into the Maven plugin, hence it should be possible to do it. The only problem is that there are several unreleased changes in libs since 2013s. Should be "safe" after the quick look
