Robert Scholte commented on MCOMPILER-360: ------------------------------------------ Just make a fork of https://github.com/apache/maven-compiler-plugin and create an integrationtest under {{src/it}}. If you don't change the code and run {{mvn verify -Prun-its}} this IT must fail with the NPE. After the fix it should succeed. That's in short how you can provide a complete patch for this issue. > nullpointer exception > --------------------- > > Key: MCOMPILER-360 > URL: https://issues.apache.org/jira/browse/MCOMPILER-360 > Project: Maven Compiler Plugin > Issue Type: Bug > Affects Versions: 3.8.0 > Environment: Linux 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 > (2018-08-21) x86_64 GNU/Linux > java version "10.0.2" 2018-07-17 > Apache Maven 3.5.4 > Reporter: Rolf Schumacher > Priority: Major > Labels: build, maven, newbie > Attachments: 2018-09-06-stacktrace.txt, pom.xml, xslt.zip > > > Trying to migrate an saxon/fop maven project to Java 10. > Added module-info.java, entered all required Automatic names.
