  <p>Project is <a href="https://bitbucket.org/LazyDevelopment/lister" rel="nofollow noreferrer">https://bitbucket.org/LazyDevelopment/lister</a></p>
  
  <p>Current branch is <a href="https://bitbucket.org/LazyDevelopment/lister/branch/7-fix-issues" rel="nofollow noreferrer">https://bitbucket.org/LazyDevelopment/lister/branch/7-fix-issues</a></p>
  
  <p>It worked fine before yesterday's evening. Today I tried to </p>
  
  <ul>
  <li>hardcode maven plugin version in mvn command </li>
  <li>re-issued tocken for SonarCloud account (new and valid tocken commited only to this branch), </li>
  </ul>
  
  <p>But without success. </p>
  
  <p>I executed the same command with -X switch, but didn't find any useful info there. Tried to find a way to attach the file with output here, but didn't. Anyway, project is opened on BitBucket, so you could go to Pipelines and check last failed jobs or download sources and reproduce the issue.</p>
