I'm trying to develop a plugin for SonarQube 5.2, however, when I deploy the plugin, the SonarQube server is unable to start. The log shows a NoClassDefFound exception with a Google Guava class:

Caused by: java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableList
at br.gov.tcu.plugins.pmd.PmdTcuPlugin.getExtensions(PmdTcuPlugin.java:48) ~[na:na]
at org.sonar.server.plugins.ServerExtensionInstaller.installExtensions(ServerExtensionInstaller.java:55) ~[sonar-server-5.2.jar:na]
... 15 common frames omitted

When I ran mvn dependency:tree the log shows that Guava is actually included, but after packaging the plugin, it does not contain the Guava jar:

You can see that I tried to remove older versions of the sonar-plugin-api, but it still didn't work.

What am I missing here?

Thanks!

I have found the issue here. The problem was in the dependency hierarchy of the sonar-xml-plugin. I had to exclude not only the older sonar-plugin-api but also the sonar-colorizer dependency.

So, in order to fix the issue, I just had to change that dependency to:

<dependency>
  <groupId>org.sonarsource.xml</groupId>
  <artifactId>sonar-xml-plugin</artifactId>
  <type>sonar-plugin</type>
  <version>1.4</version>
  <scope>provided</scope>
  <exclusions>
    <exclusion>
        <groupId>org.codehaus.sonar</groupId>
        <artifactId>sonar-plugin-api</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.codehaus.sonar</groupId>
        <artifactId>sonar-colorizer</artifactId>
    </exclusion>
  </exclusions>
</dependency>

With that change, the Guava jar gets packaged together with the rest of the libraries needed.
