Gili commented on MCOMPILER-317:
--------------------------------
[~rfscholte] If I understood you correctly, you need a list to hold the
modulepath entries and a set to hold the requirements. The modulepath would
contain both entries, but the set of requirements would only contain the
entries from the first modulepath entry.
> Plugin generates wrong modulepath (dependencies listed in wrong order)

> Key: MCOMPILER-317
> URL: https://issues.apache.org/jira/browse/MCOMPILER-317
> Project: Maven Compiler Plugin
> Issue Type: Bug
> Affects Versions: 3.7.0
> Environment: Apache Maven 3.5.2

> If a project contains dependencies with the same module name (which is valid
> according to https://stackoverflow.com/a/46573805/14731) then
> maven-compile-plugin invokes {{javac}} with a modulepath containing
> dependencies in an (apparently) arbitrary order. If I place the project in
> one directory, I get one order. If I place the project in another directory,
> I get another order. This is 100% reproducible across multiple runs, across
> different computers.
> I suspect that somewhere deep inside the code someone is using {{HashMap}}
> which is leading to undefined iteration order depending on the path being
> used.
> Expected behavior: dependencies should be listed in the same order as
> declared in pom.xml (see https://stackoverflow.com/a/793193/14731)
> Actual behavior: regardless of whether I list {{ExtensionPresent}} before or
> after {{MyLibrary}}, the wrong order gets passed to {{javac}}.
