Description Mario Abajo 2021-06-21 12:12:31 UTC

Description of problem:
As of version of openshift 4.5 maven agent image was built using Rhel 7 with maven version 3.5. It was possible to switch java version to 1.8 just adding the JAVA_HOME variable to the pod running the image. But starting with OCP 4.6, the images are now based on rhel 8 and maven 3.6, with this change in version there is also a "/etc/java/maven.conf" containing the JAVA_HOME variable already set to java-11. This seams to take any precedence so setting env variables in the pod to switch the java version is no longer possible.

Version-Release number of selected component (if applicable):
OCP 4.6

How reproducible:
Always

Steps to Reproduce:
1.
2.
3.

Actual results:
Java-11 is always used

Expected results:
Java-11 used by default but possibility to change to java-8 would be expected as with previous versions.

Comment 1 Adam Kaplan 2021-06-21 17:58:00 UTC

JAVA_HOME is not listed as one of the environment variables available to the maven agent image [1].
The maven agent image supports switching the java version via the USE_JAVA_VERSION environment variable. However, this env var is not documented [2].
