Multibranch Pipeline Indexing fails with ClassCastException in svn

    XMLWordPrintable

Details

    Description

      When I was indexing my jobs today I got an ClassCastException, the result of this mistake is hat my MultiBranch Pipeline job cannot find any branches and therefore the folder stays empty. This is a critical issue for me. I would appreciate any help. Here is my error message:

          Did you ever find a fix for this?  Most (all but one) of my multibranch pipelines are failing with this error now, but I can't pinpoint what is different.

          I hit this problem with our jenkins master and thought I was going to have to dig into some development.

          From what I can tell, the issue is that the cache for svn is outdated/corrupted and this is where the exception comes from.

          I went to my jenkins master's data location, and then into the cache directory.

          Then I did an rm of all files looking like svn-02b3b8c6-d4e4-0310-943f-b71371c1e98f.db*

          • although on your system, I guess they would look like: svn-78aad773-0322-49fb-99da-95df2966fe5b.db*

          Once I removed these files, and clicked on the 'rescan' everything was working again.

          This is based on the exception I was getting indicating that the problem was at line: https://github.com/jenkinsci/subversion-plugin/blob/master/src/main/java/jenkins/scm/impl/subversion/SVNRepositoryView.java#L115

          Hope this helps someone!
