No plugin found for prefix 'sonar' in the current project and in the plugin groups Error

Question

Everything was working fine till yesterday with Jenkins and Sonar (using Maven). Suddenly I saw below error in Jenkins logs and build fails for all projects with the same error.

[ERROR] No plugin found for prefix 'sonar' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/user/mysys/.m2/repository), nexus (http://localhost:8081/nexus/content/groups/public)] -> [Help 1]

I have sonar running and sonar plugin installed in Jenkins.

What could be the issue. Can any one help me on this regard.

Answer 1

I've the same problem since this morning .I didn't make any changes on my conf. I found a solution , on Jenkins : Manage Jenkins -> Configure System -> Sonar -> Advanced -> Version of sonar-maven-plugin , i put 2.1 and all my projects work fine now, weird ...

Answer 2

Same here. I've defined the plugin in pom (so we can also run sonar locally)

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>sonar-maven-plugin</artifactId>
                <version>2.1</version>
            </plugin>
        </plugins>
    </pluginManagement>
</build>
