    • jenkins 1.583, git plugin 2.2.6, git client plugin 1.10.2. All current versions

      When I attempt to connect to a git repo, the Git plugin returns this error below the Repository URL field:

          Does the same failure happen if you use the following URLs?

          Unfortunately, I can't duplicate the problem. The steps I took to try to duplicate the problem included:

          1. Download jenkins.war 1.583
          2. Run it from a freshly created temporary directory (JENKINS_HOME=$PWD java -jar jenkins.war)
          3. Update all the plugins to the latest versions and restart
          4. Install git plugin and restart
          5. Create a new freestyle project named "gitblit"
          6. Configure Git as the SCM for the freestyle project, with git://github.com/jenkinsci/git-client-plugin.git as the repo URL
          7. Choose gitblit as the repository browser and enter https://github.com/jenkinsgit/git-client-plugin.git

          I was running on a Ubuntu Linux 14.04 using Oracle JDK 1.7.0_67 Can you compare my steps to the steps you took in case there are relevant differences between your environment and mine?

          Per your suggestion, I tested by changing the repo to https://github.com/jenkinsci/git-client-plugin.git, and it doesn't trigger the error, so the issue must have something to do with communication with gitblit?

          It might help to note that I'm running several webapps in tomcat side by side: a home grown app, gitblit, jenkins, and solr.

          Could you also try running the test with your gitblit repository, but using jenkins.war with its self-contained HTTP server, rather than tomcat? I'd like to confirm that it is not related to your use of tomcat.

          JENKINS_HOME=/tmp/JENKINS-25013
          export JENKINS_HOME
          mkdir $JENKINS_HOME
          java -jar /usr/share/jenkins/jenkins.war --httpPort=10101

          Once that is started, install the git plugin in the Jenkins at http://localhost:10101/, define a job and confirm that it behaves the same as your tomcat configured Jenkins. I expect it will, and that will give further credence to the issue being somehow related to the gitblit browser code in the git plugin, rather than being related to your tomcat configuration.

          I'll give it a try later. In the meantime, the only thing I could do to fix it was to copy the commons-codec 1.8 jar from the jenkins war into tomcat's lib dir.

          I can't explain why Base64 would be needed by either the git plugin or the git client plugin, since neither of them have any reference to the Base64 class.

          Full stack trace may be helpful if there are nested ('Caused by') exceptions.
