Build of Maven module executed twice

[Clifford Sanders]

Hi,

Last night a build (#468) of one of our Maven projects was started by an user manually by clicking on 'Rebuild Last'.

The build was marked as FAILED although the build log says "Finished: UNSTABLE" (two tests failed).

While looking at the "Module Builds" view I saw that one of the modules was built twice #468 (green) and #469 (red).

I had a look at ${JENKINS_HOME}/jobs/myJob/builds/468/module_f/build.xml

      <upstreamBuild>460</upstreamBuild>

Build #460 was started a week ago, succeeded and is marked to be kept forever.

These are the sorted timestamps of the files/directories in ${JENKINS_HOME}/jobs/myJob/builds/468

In the job configuration "Enable triggering of downstream projects" and "Block downstream trigger when building" are enabled.

We use

- Jenkins 1.594

- Maven Project Plugin 2.8

- Rebuild Plugin 1.22 

Can someone explain to me has happened here?

Thanks
