SonarQube does not start

Question

I got a problem at SonarQube starting! In fact, it doesn't start and I don't get more informations only :

    --> Wrapper Started as Daemon  Launching a JVM...  Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.org   Copyright 1999-2006 Tanuki Software, Inc.  All Rights Reserved.   WrapperSimpleApp: Unable to locate the class org.sonar.application.App: java.lang.UnsupportedClassVersionError: org/sonar/application/App : Unsupported major.minor version 51.0   WrapperSimpleApp Usage:    java org.tanukisoftware.wrapper.WrapperSimpleApp {app_class} [app_arguments]   Where:    app_class:      The fully qualified class name of the application to run.    app_arguments:  The arguments that would normally be passed to the                    application.  <-- Wrapper Stopped  

Can someone help me?

Answer 1

We would need to set the right version of Java. In sonarqube-5.6, change the property in the file sonarqube-5.6/conf/wrapper.conf

wrapper.java.command

to

wrapper.java.command=/mypath/jdk1.8.0_73/bin/java

For Windows may need to edit from

wrapper.java.command=java 

to

wrapper.java.command=mypath\Java\jdk1.8.0_92\bin\java 

Answer 2

Install java JDK version 7u75 or higher,
Update your JAVA_HOME to point on the installed JDK directory.
Update your path to start with "%JAVA_HOME%/bin;"

Sonar require JDK 7u75 or higher : View Sonar Requirements here
