Robert Scholte commented on MCOMPILER-343:
------------------------------------------
Can you try {{plexus-java 0.9.8}} (it currently the most recent version)
> Tests fail to compile in modularized project due to wrong module descriptor
> path being passed to plexus-java
> ------------------------------------------------------------------------------------------------------------

> Key: MCOMPILER-343
> URL: https://issues.apache.org/jira/browse/MCOMPILER-343
> Project: Maven Compiler Plugin
> Issue Type: Bug
> Affects Versions: 3.7.0
> Reporter: Guy Mahieu
> Priority: Major
>
> When running a maven build on a maven project that has a module-info file and
> that has tests to compile, the build fails with the following message:
> {quote}{{Execution default-testCompile of goal
> org.apache.maven.plugins:maven-compiler-plugin:3.7.0:testCompile failed:
> java.io.IOException: Invalid path to modu}}
> {{le descriptor:
> D:\projects\DCM\dcm-nct-tcp-connector-c.v-SNAPSHOT\target\classes}}
> {quote}
> And I see that in the TestCompilerMojo class (line 273), the absolute output
> directory is passed in as the module descriptor, while in the compile of the
> production sources, the full path to the module-info.java file is passed in:
> ResolvePathsRequest<String> request =
> ResolvePathsRequest.withStrings( testPath )
> .setMainModuleDescriptor( *mainOutputDirectory.getAbsolutePath()* );
>
> For completeness I should maybe also add that I have changed my dependencies
> for the compiler plugin to be able to use java 10 and depend on multi-release
> jars (like log4j2 2.11):
> {quote}{{<dependencies>}}
> \{{ <dependency>}}
> \{{ <groupId>org.ow2.asm</groupId>}}
> \{{ <artifactId>asm</artifactId>}}
> \{{ <version>6.1.1</version> <!-- Use newer version which fixes parsing of
> module-info.java -->}}
> \{{ </dependency>}}
> \{{ <dependency>}}
> \{{ <groupId>org.codehaus.plexus</groupId>}}
> \{{ <artifactId>plexus-java</artifactId>}}
> \{{ <version>0.9.4</version> <!-- Use newer version which fixes resolving
> module-info.class files in version folders of multi release jars (needed for
> log4j) -->}}
