Following symlinks causes an OutOfMemoryException

XMLWordPrintable

      A symlink inside a node_modules folder is causing infinite recursion.

      The particular setup is when a subfolder contains a test project referencing the root project.

       

      Would there be any issues of not following symlinks to retrieve the scan targets?

       

      Adding file exclusions with iqModuleExcludes doesn't work since the whole file tree is still walked.

      Possible modification

      See here for a first draft of a possible fix: https://github.com/jenkinsci/nexus-platform-plugin/compare/master...lrpg:master

      Workaround

      • Drop the symlinks before the scan and put them back after
      • or Change the project structure (which isn't an option in some cases)
