I tried to get help at : actions/setup-java#459

I was thinking this was maybe maven cache which could be corrupted but I tried to remove cache and still face the issue.

I'm trying to investigate maven version issue ? 🤔

[sbernard31]

The issue is probably about :

• Plugin fails with upcoming Maven 3.9.0 revelc/impsort-maven-plugin#64

and :

• Maven 3.9.0 broke some build due to breaking changes. actions/runner-images#7216

I checked and :

• the build are effectively using maven 3.9 ...
• impsort-maven-plugin v1.6.2` (we are stuck to 1.6.x for java8 compatibility)

I would avoid to use maven toolchain just for impsort plugin ...
and it seems that there is no easy/official way to force the maven version in github action ... (I hope I'm wrong) and so workaround is to use script and or community actions... 😑

[sbernard31]

A workaround if integrated in master : #1411.

I asked for real fix from impsort-maven-plugin maintainer. (revelc/impsort-maven-plugin#64 (comment))

[sbernard31]

We will probably not have a release for impsort-maven-plugin v1.6.x, so at short term we should live with the current workaround.

But maybe still using java8 for build is not necessary, see #1412
