=== Cache marking
Beginning with Gradle version 8.1, Gradle supports marking caches with a `CACHEDIR.TAG` file.

It follows the format described in https://bford.info/cachedir/[the Cache Directory Tagging Specification].
The purpose of this file is to allow tools to identify the directories that do not need to be searched or backed up.

    final File lockFile = tmpDir.file('lock.bin')
    final File cacheDir = tmpDir.file('caches')
    final FileLock lock = Mock()
    final BTreePersistentIndexedCache<String, Integer> backingCache = Mock()

    private DefaultCacheCoordinator newAccess(FileLockManager.LockMode lockMode) {
        new DefaultCacheCoordinator("<display-name>", lockFile, mode(lockMode), cacheDir, lockManager, initializationAction, cleanupExecutor, executorFactory) {

        StartParameter startParameter,
        UnscopedCacheBuilderFactory unscopedCacheBuilderFactory
    ) {
        BuildScopeCacheDir cacheDir = new BuildScopeCacheDir(userHomeDirProvider, buildLayout, startParameter);
        return new DefaultBuildScopedCacheBuilderFactory(cacheDir.getDir(), unscopedCacheBuilderFactory);
    }

	// code being tested may be written. CorpusDir must be set.
	CorpusDir string

	// CacheDir is a directory containing additional "interesting" values.
	// The fuzzer may derive new values from these, and may write new values here.
	CacheDir string
}
