Broken Maven Java 10 Lombok Jigsaw Sample

This is to expose a compile error I am getting when using the lombok plugin on

openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1, mixed mode)

Reproduce the issue

• clone this repository and cd into it
• run sudo expose-issue.sh and see the output (this will run it reproducible in a docker container). Alternative just run ./mvnw clean install - it will probably result in the same

Details

When running ./mvnw clean install on this problem, the output looks like this:
