hi:
when I excute mvn sonar:sonar -P uiautomator
I got the error:[ERROR] Failed to execute goal org.codehaus.mojo:sonar-maven-plugin:2.2:sonar (d
efault-cli) on project android-sample-ui-tests: Can not execute SonarQube analys
is: Unable to execute Sonar: Fail to parse the Surefire report: F:\program files
