Answer 1

I had similar problem when upgrading to JDK17 (ie : Unsupported class file major version 61 ).

The solution was to upgrade jacoco maven plugin to version 0.8.8 in my pom

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.8.8</version>
            ...

Answer 2

I had a similar problem and fix it by chaining Gradle JVM settings in my preferred IDE which is IntelliJ (should be possible with others too):

1. In the Settings/Preferences dialog, go to Build, Execution, Deployment | Build Tools | Gradle.

2. Under the Gradle section, change the Gradle JVM option.
