Relying on just Maven Central, project not compatible with latest maven-compiler-plugin

[Stephan202]

Compared to version 3.37.0, version 3.37.1 and up contain an additional optional dependency on com.palantir.baseline:gradle-baseline. That artifact is not published to Maven Central. This was previously not a problem, but (I think) due to MCOMPILER-272, as of maven-compiler-plugin version 3.9.0, using this dependency causes a build failure when using Maven:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.9.0:compile (default-compile) on project refaster-compiler: Resolution of annotationProcessorPath dependencies failed: Missing:
[ERROR] ----------
[ERROR] 1) com.palantir.baseline:gradle-baseline:jar:4.156.0

It's not possible to simply tell Maven to exclude the dependency, because annotationProcessorPaths entries don't support <exclusions> (see MCOMPILER-395).

Given the name of this project I'm not sure you care about Maven compatibility at all, but I thought I'd share :). If nothing else it might be good to document this limitation.

NB: Of course maven-compiler-plugin should handle this better; I added a comment here.
