java.lang.UnsupportedClassVersionError: org/sonar/batch/bootstrapper/EnvironmentInformation : Unsupported major.minor version 52.0

问题:

Environment details:

• SonarQube 5.6
• Apache Maven 3.3.9
• Java version: 1.7.0_09

I integrated SonarQube plugin with java maven project like in pom.xml

<build>     <pluginManagement>         <plugins>             <plugin>                 <groupId>org.sonarsource.scanner.maven</groupId>                 <artifactId>sonar-maven-plugin</artifactId>                 <version>3.0.2</version>             </plugin>         </plugins>     </pluginManagement> </build> 

While executing goal: mvn sonar:sonar -Dsonar.host.url=<url>

Getting exception:

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2:sonar (default-cli) on project example-java-maven: Execution default-cli of goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2:sonar failed: An API incompatibility was encountered while executing org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2:sonar: java.lang.UnsupportedClassVersionError: org/sonar/batch/bootstrapper/EnvironmentInformation: Unsupported major.minor version 52.0 [ERROR] ----------------------------------------------------- [ERROR] realm = plugin>org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2

SonarQube 5.6 requires at least Java 8 (see requirements). Note that this is not a just a requirement on the server side, it's also required on the client side where analysis are ran.

Like agabrys mentioned in his comment, the Unsupported major.minor is a classic Java error (see this thread).

I just ran into this problem myself. My solution since my code and platform being developed is currently only using Java 7, and cannot use Java 8, I decided to launch the previous release/tag (5.5) with:

See tags here: Tags for sonarqube at hub.docker.com

docker run -d --name sonarqube -p 9000:9000 -p 9092:9092 sonarqube:5.5

You need at least JDK 1.8. Read more about major.minor version at: How to fix java.lang.UnsupportedClassVersionError: Unsupported major.minor version

回答4:

To further extend agabrys' and Nicolas B's answers:

You need to go to oracle's website and download an jdk of version 8.

And configure jenkins' config.xml, which normally located in /var/lib/jenkins and add an jdk:

<jdk>   <name>jdk1.8</name>   <home>/usr/java/jdk1.8.0_144</home>   <properties/> </jdk> 

in the section. Or you can add it in the jenkins web site at manage jenkins -> global tool configuration.
