----------------------------------------------------------
Passing the following options to the compiler plugin fixes the problem, but I
am looking for a way to configure Maven to do this automatically on my behalf:
{code:java}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<compilerArgs>
<arg>-Werror</arg>
<arg>--module-source-path</arg>
<arg>${project.basedir}/../*/src/main/java</arg>
<arg>--module</arg>
<arg>${module.name}</arg>
</compilerArgs>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>default-jar</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<!-- module-source-path causes the compiler to
output into classes/${module.name} instead of just classes -->
<classesDirectory>${project.build.outputDirectory}/${module.name}</classesDirectory>
</configuration>
</execution>
</executions>
</plugin>
