> {{maven-compiler-plugin}} sometime puts modularized dependencies on the
> {{javac}} {{-classpath}} option instead than {{-modulepath}}, which cause
> compilation failure. A test case is attached. Step to reproduce:
> {noformat}
> cd module-vs-classpath
> cd a
> mvn install
> cd ../b
> mvn clean install
> mvn install
> {noformat}
> The last command fail with the following error message:
> {noformat}
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile
> (default-compile) on project b: Compilation failure
> [ERROR] module not found: test.a
> {noformat}
> Execution with the {{-X}} option shows that the {{test.a}}Â dependency is
> correctly declared in {{-modulepath}} when executing {{mvn clean install}},
> but is wrongly declared in {{-classpath}}Â when executing {{mvn install}}.
> A workaround is to remove the
> {{<useIncrementalCompilation>false</useIncrementalCompilation>}} option in
> the {{pom.xml}} files, or to execute {{touch src/main/java/module-info.java}}
> before {{mvn install}}. However the same error message occurs when attempting
> to execute {{mvn site}}, for which case I have found no workaround yet (note:
> the {{mvn site}} problem is not reproduced by the attached
> {{module-vs-classpath.zip}} file).
