SonarQube /api/resources - 500 内部服务器错误

SonarQube /api/resources - 500 Internal Server Error

我在 Jenkins 上使用 [slack-sonar-pusher][1],但是当我 运行 作业时,我得到了这个输出:

 [ssp] Calling SonarQube on: http://xxx.xxx.x.xx:9000/api/resources?metrics=alert_status,quality_gate_details&includealerts=true
 [ssp] Got a non 200 response from SonarQube. Server responded with '500 : Internal Server Error'
 [ssp] Could not get Sonar results, exception: 'null'
 Build step 'Sonar Slack pusher' marked build as failure

如果我直接在浏览器中打开http://xxx.xxx.x.xx:9000/api/resources?metrics=alert_status,quality_gate_details&includealerts=true url,我收到了正确的内容

有人知道问题出在哪里吗?

已解决:
