John Patrick commented on MCOMPILER-421:
----------------------------------------
With `mvn compile` I get this the following issue, so no idea what your
suggesting;
{code}
[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR]
PATH/org.apache.maven_maven-compiler-plugin_MCOMPILER-422/workaround-no-provides/service-implementation/src/main/java11/module-info.java:[3,31]
error: module not found: workaround.service.interfaces
[INFO] 1 error
{code}
Regarding `mvn clean install`, yes I am aware most people suggest `mvn clean
verify` but I find using verify does not work in lots of situations. When
working with lots of git repos, it saves have to do lots of little releases of
minor changes. And I know lots say why are you install lots into your repo and
it just grows over time, which is why I use this to automatically clean old
releases from your local repo.

> Project: Maven Compiler Plugin
> Issue Type: Improvement
> Affects Versions: 3.8.1
> Reporter: John Patrick
> Priority: Major
>
> If you have the following structure you have to recompile everything for each
> version supported.
> If you have the following code;

> src/main/java14/package/Example.java (7)
> src/main/java14/package/Java14.java (8)
> src/main/java14/module-info.java (9)
> {code}
> I expect the following jar structure;
