ClassCastException while extracting e-mail author from

    XMLWordPrintable

Details

    Description

      We have this issue in our Hudson environment, that since we created some projects that use the GIT SCM plugin, any jobs that are using Subversion now report this exception. Somehow the GIT plugin seems to interfere with the build jobs that use subversion, even though the subversion jobs have no reference to GIT in their configuration.

      The problem happens when the Hudson job tries to extract e-mail information about SVN author: as there are different authors from both GIT and SVN in the overall Hudson jobs, it seems that all of them are assumed to come from SVN.

      See below the exception:

          1) do you see any exceptions like this that are not for maven project?
          2) look in the builds/*/changelog.xml files for some of your maven projects.. can you find any that contain "subversion" but the maven project uses Git for its SCM?

          did you have any projects that once used subversion but then you changed the SCM to git?

          I experienced the same exception after moving a project from Subversion to Git. I reconfigured it by changing the SCM from Subversion to Git. After that I got the exception when entering the People page. I resolved the problem by deleting the job and creating a new.

          Hi,

          it is actually the case: the jobs were originally using SVN and then they have been moved to GIT.
          Anyway this is a fairly common scenario as people will be moving from SVN to GIT: is there an assumption that a Project cannot change its SCM in his history then ?

          May I go and fix this without opening any "Pandorra vase" ?

          Thank you for your help.

          Luca.
