Re: Maven Build Cache Extension Hash Of Configuration

Hi Nils,
I did try, but after I looked at the source code, it appears because the default location of the configuration is placed inside an hidden directory, I can't add it as an input.

For reference (Tag 1.2.0) org/apache/maven/buildcache/checksum/MavenProjectInput.java:480

So this seems to be not supported at all.

Have you tried via maven.build.cache.input?
