android - Sonar fails to connect to mysql, running from gradle



I have a sonar configuration that looks like this:

sonar.jdbc.validationQuery=select 1

And when running this from my gradle script, which looks like this:

  sonarProperties {

        property "sonar.projectKey", "sonar-example"
        property "sonar.projectName", "sonar example"
        property "sonar.projectVersion", "1.0"

        property "sonar.sources", "src/main/java"
        property "sonar.binaries", "build"
        property "sonar.test", "src/test/java"

        property "sonar.language", "java"
        property "sonar.profile", "Android Lint"
        property "", "lint-report.xml"
        property "sonar.dynamicAnalysis", "reuseReports"
        property "sonar.sourceEncoding", "UTF-8"

        property "sonar.junit.reportsPath", "build/outputs/reports/coverage/debug"
        property "sonar.cobertura.reportPath", "build/outputs/reports/coverage/debug/cobertura.xml"
        property "", "cobertura"

        property "", "http://localhost:9000/sonar"
        property "sonar.jdbc.username", "sonar"
        property "sonar.jdbc.password", "sonar"


I get the following error:

Why is it connecting to H2 and not mysql? I've read the post with the same problem here and here, but the solution seems to have been something related to Maven. I don't use Maven, I use Gradle instead.


property "sonar.jdbc.url", "jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance"

should be added to sonarproperties above.

android gradle sonarqube sonar-runner

The (most important) property sonar.jdbc.url is missing in the sonarProperties section of your Gradle script, so no wonder why it is trying to connect to H2 (which is the default value for this property).

Have you tried replacing property "", "http://localhost:9000/sonar" with property "", "" ?
