             Summary: Corrupt files apearing during concurrent Hudson runs
                 Key: JBTM-1233
                 URL: https://issues.jboss.org/browse/JBTM-1233
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Testing
            Reporter: Paul Robinson
            Assignee: Paul Robinson
             Fix For: 4.17.0, 5.0.0.M2


The narayana.sh build script builds narayana and jbossas each time it's run. Artefacts are installed to a maven repo that is shared among all Hudson jobs. This can cause corrupt files if multiple jobs write to the same location in the repo at the same time. This is a common occurrence as the Hudson QE cluster has many jobs that execute the narayana.sh script and it is not uncommon for these jobs to run at the same time.

A simple solution would be to have the script use a maven repo that is local to the Hudson slave, rather than the shared one that is used at the moment. This maven repo would need to defer to the shared maven repo for unavailable artefacts. New artefacts would be installed to the local repo. This would ensure no shared access occurs as the Hudson slave will only be used by one job at a time.

This configuration would need to be option (and non-default) as it would not be desirable for developer or Newcastle-Hudson use.
