I want to analyse project with SonarQube
while doing this it gives me a error message saying

Error during execution of Sonar Error status [command: C:\Program Files (x86)\Java\jdk1.6.0_18\jre\bin\java.exe -cp C:\Users\qfrg\AppData\Local\Temp\sonar-runner-impl7722306846094038579.jar org.sonar.runner.impl.BatchLauncherMain C:\Users\qfrg\AppData\Local\Temp\sonar-project6654886318444556353.properties]: 1

In the console log i see this :

Caused by: org.sonar.api.utils.SonarException: The plugin javascript is not supported with Java 1.6.0_18
Caused by: java.lang.UnsupportedClassVersionError: org/sonar/plugins/javascript/JavaScriptPlugin : Unsupported major.minor version 51.0

I installed plugins for findbugs, checkstyle, PMD and M2Eclipse successfully before installing sonarqube, but after installing sonarqube, when i tried to add them again they say that

Unable to connect to repository http://eclipse-cs.sourceforge.net/update/compositeContent.xml Connection to http://eclipse-cs.sourceforge.net refused

Please find my version and plugin details:
java:

java version "1.6.0_18" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)

maven:

Apache Maven 3.0.3 (r1075438; 2011-02-28 23:01:09+0530) Maven home: C:\dev\apache-maven-3.0.3-bin Java version: 1.6.0_18, vendor: Sun Microsystems Inc. Java home: C:\Program Files (x86)\Java\jdk1.6.0_18\jre Default locale: en_US, platform encoding: Cp1252 OS name: "windows 7", version: "6.1", arch: "x86", family: "windows" 

and

SonarQube Server 4.5.4
Eclipse : Kepler Service Release 2

And i am using TFS as source control Where am i going wrong ? Is this the problem with java version ? As, I have seen in some sites that it worked for them when upgraded to 1.7 version of java

Any help greatly appreciated

  • Major.minor version 51.0 means J2SE 7, [see here](http://stackoverflow.com/a/11432195/136363) for a more thorough explanation on version numbers. Basically this means it's not compatible with J2SE 6.0, which you're trying to use it with. Try upgrading your Java version or getting an older version of SonarQube and/or the Javascript plugin. – t0mppa Jul 15 '15 at 03:58
  • SonarQube 4.5.4 server needs based on different plugins Java 1.7. Downgrading does not work. Furthermore don't use Maven 3.0.3 anymore... – khmarbaise Jul 15 '15 at 06:33

Please check your internet connection and retry. Read timed out"** – Raaji Jul 22 '15 at 07:22

As mentionned in the Requirements documentation page, Java 7 at least is required to run SonarQube server and SonarQube analyses.

You are using a Java 6 virtual machine, this is why you get those error messages.
