I have a Jenkins job that uses Ant to build a project.
The project is in Java 7. The runtime for the Jenkins job is also Java 7. I'm using SonarQube 5.6.1 which runs on Java 8. SonarQube server is running fine.
However, when it's time to invoke the <sonar:sonar /> target in Ant, I get the following error which clearly is due to a Java version mismatch (JVMCFRE003 bad major version). I am not sure how to solve this.

The problem is that we're talking about a Jenkins job, and the version of Java used for the job will be used for each step in the job. Since you're running the job with Java 7, the analysis is also running with Java 7 & that's not compatible with SonarQube 5.6+.
The easiest thing to do is move analysis from the Ant script into a SonarQube Scanner Build Step; it will let you choose a different Java version from the one running the job.
Alternately you could maybe accomplish this with a pipeline
node() {
def jdk8 = tool 'jdk-8u45'
def jdk7 = tool 'jdk-7u70'
withEnv(["PATH+JDK7=${jdk7}/bin"]) {
sh 'ant [normal target here]'
}
withEnv(["PATH+JDK8=${jdk8}/bin"]) {
sh 'ant [analysis target here]'
}
}
Your third option would be to split the job in 2 and use a shared workspace (Configure > Project Options > Advanced > Use custom workspace)
