[MBUILDCACHE-107] pom.xml properties 'maven.build.cache.*' are not part of the effective pom involved by the checksum

Changing a pom.xml property like `maven.build.cache.exclude.glob.1` does not impact the input checksum and therefore keeps using the wrong cache entry. The only remediation is to remove the cache entry manually.

Start with the pom.xml properties named in the issue, especially maven.build.cache.exclude.glob.1, and inspect how the effective POM contributes to the input checksum. Review linked pull request #181 for the work already underway. Done means changing one of these properties produces a different checksum and no longer reuses the wrong cache entry.
