Does SonarQube support Java 8 yet?

Question

With Java 8, executing gradle sonarRunner shows this error message. (sonarQube version : 4.2.1)

java.lang.ArrayIndexOutOfBoundsException: 26721

Does SonarQube not support Java 8 yet? I would like to know when support is available.

Thank you.

Answer 1

There are 2 sides to your question:

1. The sonarRunner (client)
2. The SonarQube application (server)

The error you receive comes from the Java Ecosystem plugins that are downloaded to the client and rely on an old version of ASM (3.2). AFAIK Java 8 support starts with version 5.0. You'll have the same issue with Findbugs and Jacoco. See also this discussion.

Concerning the SonarQube server, you can start it, but it crashes when you select "Configure widgets", so I would say no, it does not support Java 8 yet.

Answer 2

SonarQube supports Java 8 since end of March 2014 (with some hickups at first, which were fixed in version 2.2 of its Java plugin).

I had to uninstall the PMD and Checkstyle plugins in Sonar's update center as those are not ready for Java 8. Sonar's own rule engine Squid should make those plugins redundant anyway.

If you are using Gradle 1.11 to call Sonar and want Jacoco to calculate code coverage, you'll have to specify the latest Jacoco version in order to analyze Java 8 bytecode.

Here's my script that does that when called with gradle test jacocoTestReport sonarRunner:

/** This script is responsible for unit testing and static analysis of the project source code*/

apply plugin: "jacoco"
apply plugin: "sonar-runner"

// Location of the XML unit test and code coverage reports 
def testResultsDir = "$buildDir/test-results/" // Use double quotes. Otherwise the $ won't work

jacoco{
    // Gradle 1.11 ships with a Jacoco version that doesn't support Java 8
    toolVersion = "0.7.0.201403182114"
}
// Call "gradle test jacocoTestReport" to produce a code coverage report at "build/reports/jacoco/test/html/index.html"
test {
    jacoco {
        def coverageReport = new File(testResultsDir, "jacocoTest.exec")
        destinationFile = file(coverageReport)
    }
}

// Let SonarQube analyze the project
sonarRunner {
    sonarProperties {
        property "sonar.projectKey", projectId
        property "sonar.projectName", projectName

        property "sonar.junit.reportsPath", testResultsDir

        // Address of SonarQube server
        property "sonar.host.url", "http://localhost:9000"

        // SonarQube stores the test results in this database
        property "sonar.jdbc.url", "jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true"
        property "sonar.jdbc.driverClassName", "com.mysql.jdbc.Driver"
        property "sonar.jdbc.username", "root"
        property "sonar.jdbc.password", sonarDBpassword
    }
}

It will be supported very soon. See http://jira.codehaus.org/browse/SONARJAVA-386.
