Unsupported class file major version 55 when executing sonar-maven-plugin under openjdk11

Question

i looked around the similar issues and replies, but did not find the solution for mine.

I am using openjdk11 and apache-maven-3.5.4 for my project compile and package, everything works fine and the application is running normally.

But on my executing the sonar analysis based on connecting to sonarcube server via maven commands, it failed and some issue happen. This command worked when i was using jdk6 and maven 3.2.1.

The maven command used: mvn sonar:sonar -Dsonar.host.url={mysonarcube.server} -Dsonar.login={mysonartoken}

The key pom.xml relates to sonar:

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>

            </configuration>

                <dependency>

                </dependency>
            </dependencies>
        </plugin>
        <plugin>
            <groupId>org.sonarsource.scanner.maven</groupId>
            <artifactId>sonar-maven-plugin</artifactId>
            <version>3.5.0.1254</version>
        </plugin>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.7.9</version>
            <configuration>
                <destFile>${sonar.jacoco.reportPath}</destFile>
                <append>true</append>
            </configuration>
        </plugin>

The error message as follows:

Could anyone help or give me some hint, thanks.

SonarJava analyzer installed on your server is most probably <5.8

To be able to analyze Java 11 binary files you need to upgrade to SonarJava 5.8+ on your sonarqube instance.
