[jira] [Created] (MCOMPILER-311) NPE when --patch-module is used

Zhihong Zhang created MCOMPILER-311:
---------------------------------------

             Summary: NPE when --patch-module is used
                 Key: MCOMPILER-311
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-311
             Project: Maven Compiler Plugin
          Issue Type: Bug
    Affects Versions: 3.7.0
         Environment: Java 10 in Windows 10
            Reporter: Zhihong Zhang


When "--patch-module" argument is added to the compiler, the plugin always throws NullPointerException. For example,

{{          <compilerArgs>
              <arg>--patch-module</arg>
              <arg>java.xml.ws.annotation=jsr305-3.0.1.jar</arg>
          </compilerArgs>
}}
The bug is caused by an not implemented method in CompilerMOJO.java,

{{    @Override
    protected Map<String, JavaModuleDescriptor> getPathElements()
    {
        // TODO Auto-generated method stub
        return null;
    }}}
