Pipeline step fails on Maven error

[ktatro-rh]

On the pipeline build step, everyone in our workshop experienced the following error during the workshop:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project nationalparks: Fatal error compiling: invalid target release: 11 -> [Help 1]

[open-sudo]

The PVC doesn't bind. It stays indefinitely in PENDING state.

I did some looking at some other user namespaces, it looks like the PVC was correctly bound in the namespaces, but the pipeline still failed. Here is the full output from the build-and-test log:

+1 to this error (the pvc is binding). Do we have any work arounds for this?

Solution : Looks like the issue is with the maven image in the pipeline build-and-test step. The image is defaulting to "gcr.io/cloud-builders/mvn" which will pull the latest and may not have the java 11.

Changing the image tag to a previous one (the one below worked) solved the problem:
gcr.io/cloud-builders/mvn@sha256:8e7d8d214e2c007f8b4737beb393c941bb9a11600eeedfc0c2bcec3dc8d11e06

Update : The fix seems to have been applied. The workshop uses Maven 3.9.1 that was released a few days ago. I did another run and the step is successful. This can be closed !
