声纳抱怨“ SonarQube分析已经在进行中”

我正在尝试通过Maven运行Sonar分析，但它一直在抱怨：

[ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.7.1:sonar (default-cli) on project mio-commons: Another SonarQube analysis is already in progress for this project -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:

此项目尚无任何分析，我什至尝试从Sonar中删除项目本身。任何想法可能是什么问题？

我想解决了，删除了${basedir}/.sonar文件夹。
