Description

Resolves a cache miss caused by an absolute path present in Checkstyle's configProperties extension property. The cache_file entry in configProperties was previously being set to the absolute path of the cache file.

The value of the cache_file entry has been updated to the relative path to the cache file from Checkstyle's configDir. The value of configDir is available in checkstyle.xml as config_loc, per the Gradle documentation here. In checkstyle.xml, the cache_file relative path is then appended to config_loc to construct the full path to the cache file.

Updating configProperties to only contain relative paths avoids cache misses that may occur based on the absolute path of the repository.

Motivation and Context

Avoiding absolute paths in input properties ensures that the project can take full advantage of both the local and remote build caches from either local or CI builds independent of the absolute path of the repository.

How Has This Been Tested?

Running a clean build shows that the Checkstyle cache file is still written at the correct path - build/checkstyle/cacheFile.

Gradle's build validation scripts show configProperties input differences before this fix was applied, and no input differences with the fix applied.
