使用Sonar配置Maven，jenkins

Question

I have installed Jenkins and Sonar, both work fine. I am able to build a maven android project using Jenkins. No i want to run Sonar on the android project. I have installed the Sonar plugin in Jenkins. Configured the sonar module in the configure system module and added a post build task for sonar to run

1. From the error message its clear that mvn is trying to download the sonar-maven-plugin from your local Nexus repository which does not seem to have it.

2. Try mvn -U in the build in case you already have the plugin.This overrides the negative cache. Another thing is <updatepolicy> in your settings.xml

3. If you don't have the plugin and neither does your Nexus connect to the internet, you have to manually download and upload in Nexus of course. Please remember to match the version of the plugin with the SONAR installation. Also there would be a few (7-10) transitive dependencies with the plugin which you will need. I suggest using mvn -X or mvn -e to see a verbose output during your testing.
