Not working with Gradle 5.0

Nobody has claimed this yet.

When I apply the latest version (0.2.2) to my project I got a weird build error:
* What went wrong:
Execution failed for task ':admanager-api:compileJava'.
> java.lang.ClassCastException: com.sun.tools.javac.processing.JavacProcessingEnvironment cannot be cast to com.sun.tools.javac.processing.JavacProcessingEnvironment

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':admanager-api:compileJava'.

After I switch to any older version (0.1.0, 0.2.0, 0.2.1), I got another error which also does not make much sense to me:

Start by reproducing the :admanager-api:compileJava failure with Gradle 5.0 and the listed plugin versions. Read the stack trace around Checker Framework annotation processing and the plugin's build configuration; done means identifying and verifying a compatible build across the reported versions.
