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.
