Hi,
lately we have had a ton of failed builds on the build server related to file management,
stuff like:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-jar-plugin:2.4:jar (default-jar) on project gs-restconfig-wcs: Error assembling JAR: /var/lib/jenkins/workspace/java11/geoserver/src/restconfig-wcs/pom.xml isn’t a file. → [Help 2]
or:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-jar-plugin:3.1.0:jar (default-jar) on project gt-xsd-fes: Error assembling JAR: /var/lib/jenkins/workspace/java11/geotools/modules/extension/xsd/xsd-fes/pom.xml isn’t a file. → [Help 3]
I’m guessing this is due to “too much sharing” between the builds, which are running with higher concurrency.
I believe Jody modified them to have different versions to build in parallel, is that right?
I see a “Build A”, “Build B”, “Build C” throttling categories but it’s not clear to me what they relate to… but I see multiple
builds running in parallel, that should not, here:
Why not? Because for example the first two are sharing the same /var/lib/jenkins/workspace/java11/geoserver workspace.
If we want for them to run in parallel, at a minimum there should be a different workspace per version of GeoTools/GeoServer
(and a separate one between java 8 and java 11).
I’m also not sure the local maven repository is designed to allow multiple builds to modify it at the same time. Either
multiple repos are used for the different categories, or the concurrent safe local repo Maven plugin should be installed:

Let’s discuss it at tonight’s meeting
Cheers
