Custom qualifiers and Maven setup

[fritzfs]

Hey!

I'm trying to recreate the example with a custom qualifier from the documentation, but with a Maven setup, and I'm failing.

error: SubtypingChecker: could not load class for annotation: org.example.safe.qualifiers.Encrypted. Ensure that it is a type annotation and your classpath is correct.

Since I need to compile qualifiers before I start to compile other code, what is the recommended way to have to set this up? Using Maven Modules?

https://checkerframework.org/manual/#subtyping-example

https://checkerframework.org/manual/#maven

This is my change to maven pom:

<annotationProcessors>
    <annotationProcessor>org.checkerframework.common.subtyping.SubtypingChecker</annotationProcessor>
</annotationProcessors>
<compilerArgs>
    <arg>-Xmaxerrs</arg><arg>10000</arg>
    <arg>-Xmaxwarns</arg><arg>10000</arg>
    <arg>-Aquals=org.example.safe.qualifiers.Encrypted,org.example.safe.qualifiers.PossiblyUnencrypted</arg>
</compilerArgs>

Thanks!
