SonarQube on Java8-project gives jacoco-Exception

Question

I just downloaded the latest version, SonarQube 4.3, then try build a java-8 project with: ``` mvn clean install mvn sonar:sonar ``` That gives me the Exception below. Googling, I got the impression this is an earlier issue that should have been fixed... ? http://sonarqube.15.x6.nabble.com/Sonar-analyze-Java-1-8-project-Failure-td5023663.html http://jira.codehaus.org/browse/SONARJAVA-482 Does SonarQube 4.3 support java-8? Or any clue, what is the problem? ``` ------------------------------------------------------- T E S T S ------------------------------------------------------- java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.jav…

Accepted Answer

I got the missing info from the SonarQube mailing-list... To summarize:

To get Java8 maven-build working on SonarQube-4.3:

Install sonarqube-4.3, and start the server.

Login to the web-gui => Settings => Update Center => Plugins Updates => Java => Click "Upgrade to 2.2.1"

Wait a minute or so for the upgrade to complete... then shutdown+restart sonarqube. Go back into the Upgrade Center and verify you have plugin: Java 2.2.1

To get code-coverage in Sonar, you now need to build with these commands:

```
mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent install 
mvn sonar:sonar
```

That's it.
