Unsupported major.minor version 52.0

[Stas Roshkolets]

Hello,
we get an error "Caused by: java.lang.UnsupportedClassVersionError: hudson/plugins/sonar/SonarRunnerInstallation$1 : Unsupported major.minor version 52.0" while running Sonar job in Jenkins.
The Node where sonar-runner runs already has JDK1.8:

> java -version

java version "1.8.0_60"

Java(TM) SE Runtime Environment (build 1.8.0_60-b27)

Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

 > javac -version

javac 1.8.0_60

Do you know what can be an issue?

Hi Stas,

Could you please send us the SonarQube version, and some more logs about the analysis ?

Regards,

Hi,

Sonar-scanner needs Java 8. So in your case, please try running Jenkins with Java 8.

[Stas Roshkolets]

Hi,
Also Jenkins use Java 8

jenkins@illin4237!:jenkins> java -version

java version "1.8.0_60"

Java(TM) SE Runtime Environment (build 1.8.0_60-b27)

Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

jenkins@illin4237!:jenkins> javac -version

javac 1.8.0_60

And sonar-runner run on the node/slave and not on master itself so it should be related to node/slave configurations and no Jenkins, right?

[Stas Roshkolets]

Hello,
Issue was solved by changing Sonar version number in "Manage Jenkins" configuration.
Before we had Sonar plugin 2.3 and there was no need to set Sonar version in Jenkins configuration.
After upgrading Sonar plugin to version 2.5 this setting appear and was by default set to "5.3 or lower" and our Sonar version is 5.5

[chitr...@gmail.com]

Does this fix below worked?

I recently upgraded Sonar plugin to 2.5 and running Sonar instance on 5.6.6

[Stas Roshkolets]

Actually,
Changing Node configurations in Jenkins helped.
It was set to use java 1.7 instead of java 1.8 in "Advanced" section of Node/Slave settings.
