报错及修改：
报错：INFO: Can't get Compute Engine task status.Retry...
org.sonarqube.ws.connectors.ConnectionException: HTTP error: 401, msg: , query: org.apache.commons.httpclient.methods.GetMethod@7a021f49
ERROR: Problem generating PDF file.
org.sonar.report.pdf.entity.exception.ReportException: Can't get Compute Engine task status.
ERROR: PDF file not found in local filesystem. Report could not be sent to server.
问题解决：这个应该是没有权限（很可能是你Admin修改账号密码的时候，你pdf没有修改）
点击配置-PDF Report-修改密码-保存
