We cannot load our custom built sonar plugins for java

Must-share information (formatted with Markdown):

which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
how is SonarQube deployed: zip, Docker, Helm
what are you trying to achieve
what have you tried so far to achieve this

Hi,

We have upgraded to SonarQube CE 9.9 LTS. ( We used 8.9 before).
We try to deploy a new version of our custom plugin in /opt/sonarqube/extensions/plugins but sonarqube fails to start and if I check the web.log I can see the below.

Hello Mikael,

As the error states, a dependency can not be loaded:

Caused by: java.lang.ClassNotFoundException: com.google.common.collect.ImmutableList

The class loader will not load those dependencies automatically as you would expect. I found that the easiest way to get around this is to simply include the dependencies in the plugin jar itself. You can do that with maven-shade-plugin.

@Hendrik_Buchwald so there has been some changes since this has been working in older versions of SQ?

We use the following in out plugin pom.xml

 <build>
        <plugins>
            <plugin>
                <groupId>org.sonarsource.sonar-packaging-maven-plugin</groupId>
                <artifactId>sonar-packaging-maven-plugin</artifactId>
                <version>${sonar.packaging.maven.plugin.version}</version>
                <extensions>true</extensions>
                <configuration>
                    <pluginKey>java-mje-custom-rules</pluginKey>
                    <pluginName>Java MJE Custom Rules</pluginName>
                    <pluginClass>com.company.msran.sonarqube.java.JavaCustomRulesPlugin</pluginClass>
                    <sonarLintSupported>true</sonarLintSupported>
                    <!-- allow to depend on API 6.x but run on LTS -->
                    <sonarQubeMinVersion>5.8</sonarQubeMinVersion>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>${maven.compiler.plugin.version}</version>
                <configuration>
                    <source>${java.version}</source>
                    <target>${java.version}</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

Do we need to change it?

br,

I am not aware of any changes in that regard but then again, I am also not involved in that part of development at all. I will ping the responsible team, they will be of better help with this.

If I would have to guess, maybe we just used to include that module by default and don’t do that anymore. But that is really just a guess.

Hello Mikael,

As we have not heard from you in the meantime, have you been able to make it work?

As Hendrik already indicated, you will need to package the Guava dependency in your plugin jar file if you want to use it. The Java analyzer previously used Guava, however, we have removed this dependency in the meantime, as newer Java versions provide a more convenient collection API. So you cannot rely on it being in the classpath anymore.
