liberty-maven-plugin should rely on the build toolchain configuration to build / rebuild code

[andre-doherty]

Hello,

I am noticing the following behavior when using the liberty maven plugin in dev mode.

Description of the issue :
The jdk used to invoke maven is used to build / rebuild code (such as unit tests) regardless of the build toolchain that maven is build upon.

How it should behave :
Whenever a build toolchain configuration is defined in the maven setup it should be used by the liberty-maven-plugin
see : https://cwiki.apache.org/confluence/display/MAVENOLD/Toolchains

Regards,
André

Agreed. We have #1630 open as well though haven't prioritized it yet.

Sorry i didn't spot that one.
Yeah that's an issue for instance when you have to deal with jdk8 and below component, eg when the running jdk doesnt have jaxb / jaxws support as in jdk11+, units tests wont even compile when in dev mode whenever they are perfectly ok in a basic mvn clean install use case.

No problem. I won't promise anything exactly but I'll remind the team to take another look as we prioritize in 2024. Thanks for bringing this up again.
