publish html report报错：This is especially strange since your build otherwise succeeded

jenkins配置publish html report显示HTML测试报告报错：

[htmlpublisher] Archiving HTML reports...
[htmlpublisher] Archiving at BUILD level /home/jenkins/workspace/***/test-output to /var/jenkins_home/jobs//***/builds/60/htmlreports/HTML_20Report
ERROR: Directory '/home/jenkins/workspace//***/test-output' exists but failed copying to '/var/jenkins_home/jobs//***/builds/60/htmlreports/HTML_20Report'.
ERROR: This is especially strange since your build otherwise succeeded.
Build step 'Publish HTML reports' changed build result to FAILURE
perform:构建结果FAILURE,发送策略:ALL
Finished: FAILURE

日志显示：生成HTML报告时，出现异常，才导致报错

开发Jenkins插件的时候， maven install报错：
Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.0.0-M1:enforce (display-info) on project QaJenkinsPlugin: Some Enforcer rules have failed. Look above for specific messages explaining why the rule failed. -> [Help 1]

原因：maven没有配置，使用idea自带的3.0.5的版本，后续改成3.3.9版本后修复
