Major Description
PMD 5.6.0 supports an incremental analysis cache, which speeds up the PMD run. Only changed files need to be checked again.
In m-pmd-p, a new property should be added to configure the location of the cache file (preferrably analysisCacheLocation=target/pmd/pmd.cache) and another property to enable/disable this feature (e.g. analysisCache=true).
