James Gough commented on MTOOLCHAINS-28: ---------------------------------------- [~madmax25] I'm going to start trying to recreate this issue. If you have a small project you can zip and attach to this issue that would be great, otherwise I'll try go with what is above. > Toolchain does not respect fork > ------------------------------- > > Key: MTOOLCHAINS-28 > URL: https://issues.apache.org/jira/browse/MTOOLCHAINS-28 > Project: Maven Toolchains Plugin > Issue Type: Bug > Affects Versions: 1.1 > Environment: Java 11, JDK 1.8, Maven 3.5.0 > Reporter: Max Edmiston > Priority: Major > > I am using maven-compiler-plugin with fork option, configured for Java 11 > using the toolchain plugin. I have set my local environment to use JDK 1.8 by > default. Forked process will use JDK 1.8, not Java 11, even with toolchain.
