title: Cannot lock file hash cache when gradle was aborted
body: <p>I canceled a running Gradle build and now I get the following message whenever I restart it:</p>
  <pre><code>Could not create service of type FileHasher using BuildSessionServices.createFileHasher().
     &gt; Cannot lock file hash cache (/data/.gradle/6.4.1/fileHashes) as it has already been locked by this process.
  </code></pre>
