Error integrating Azure DevOps Classic Pipeline with SonarCloud: Java version issue

Question

I am encountering an issue while attempting to integrate an Azure DevOps classic pipeline with SonarCloud for a Java project that utilizes Maven for package management.

I initially tested this SonarCloud integration using Jenkins, where it appeared to be a Java version issue. However, even after upgrading the Java version on the server and updating certain SonarQube plugins, the error persists. Consequently, I decided to switch to Azure DevOps, but I am still encountering the same issue.

Following steps have been taken:

• I upgraded the Java version on the server and updated certain SonarQube plugins. I was expecting these changes to resolve the compatibility issue with SonarCloud.
• Upgraded the Jenkins version as well but no change in the response.
• Changed the JDK version to 17, then I received the following error

Could someone provide guidance or assistance in resolving this issue? Any insights or suggestions would be greatly appreciated.

For this issue, this means that you need to upgrade your java version.

Fatal error compiling: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x1667a6f7) cannot access class..

After you upgrade Java version to 17, the cause of this issue is that the dependency org.projectlombok version is not compatible with Java version.

I can reproduce the same issue when using version 1.18.10.

To solve this issue, you need to upgrade the version of dependency org.projectlombok(e.g. version 1.18.28).

For example:

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.28</version>
        <scope>provided</scope>
    </dependency>
