sshagent block serialization error when script with git clone fails

XMLWordPrintable

      We have a pipeline that looks something like:

      node {
    sshagent (credentials: ['ssh-id-rsa']) {
        sh 'run-somescript.sh > build.log'
     }    
}

      Where the script checks out a git repo via ssh.

      git clone --recursive git@github.com:...

      The repo also contains a https submodule.

      Sometimes, we see this error from the submodule.

      Submodule 'module' (https://github.com/<org>/<repo>.git) registered for path 'module'
Cloning into 'module'...
error: index-pack died of signal 15
fatal: index-pack failed
fatal: clone of 'https://github.com/<org>/<repo>.git' into submodule path 'module' failed

      Somehow though, this is causing a serialization exception in the pipeline.

      an exception which occurred:
