Gradle / Jacoco / SonarQube issues - gradle

Question

I'm going to put a fat bounty on this as soon as the system permits.
What I'm specifically having trouble with is getting coverage and getting integration tests working. For these I see the uninformative error:
Resource not found: com.something.somethingelse.SomeITCase
Uninformative because there's nothing to relate it to, nor does it mean much to someone who has none of the context.
Here's other weirdness I'm seeing. In cases where there's no integration tests for a subproject, I see this:
JaCoCoItSensor: JaCoCo IT report not found: /dev/build/dilithium/target/jacoco-it.exec
Why would I see target? This isn't a Maven project. A global search shows there's no target directory mentioned anywhere in the code base.
Then, there's this section of the documentation:
sonarqube {
properties {
properties["sonar.sources"] += sourceSets.custom.allSource.srcDirs
properties["sonar.tests"] += sourceSets.integTest.allSource.srcDirs
}
}
Near as I can tell sourceSets.integTest.allSource.srcDirs returns Files, not Strings. Also it should be:
sonarqube {
properties {
property "sonar.tests", "comma,separated,file,paths"
}
Note that you get an error if you have a directory in there that doesn't exist. Of course there's apparently no standard for what directory to put integration tests in and for some sub-projects they may not even exist. The Gradle standard would be to simply ignore non-existent directories. Your code ends up looking like:
sonarqube {
StringBuilder builder = new StringBuilder()
sourceSets.integrationTest.allSource.srcDirs.each { File dir ->
if ( dir.exists() ) {
builder.append(dir.getAbsolutePath())
builder.append(",")
}
}
if (builder.size() > 1) builder.deleteCharAt(builder.size() -1 )
if (builder.size() > 1 )
properties["sonar.tests"] += builder.toString()
properties["sonar.jacoco.reportPath"] +=
"$project.buildDir/jacoco/test.exec,$project.buildDir/jacoco/integrationTest.exec"
}
Sonar is reporting no coverage at all. If I search for the *.exec files, I see what I would expect. That being:
./build/jacoco/test.exec
./build/jacoco/integrationTest.exec
...but weirdly, I also see this:
./build/sonar/com.proj_name_component_management-component_proj-recordstate/jacoco-overall.exec
What is that? Why is it in such a non-standard location?
OK, I've added this code:
properties {
println "Before: " + properties.get("sonar.tests")
println "Before: " + properties.get("sonar.jacoco.reportPath")
property "sonar.tests", builder.toString()
property "sonar.jacoco.reportPath", "$project.buildDir/jacoco/test.exec,$project.buildDir/jacoco/integrationTest.exec"
println "After: " + properties.get("sonar.tests")
println "After: " + properties.get("sonar.jacoco.reportPath")
}
...which results in:
[still running]

Answer 1

I don't want any bounty or any points.
Just a suggestion.
Can you get ANY Jacoco reports at all?
Personally I would separate the 2: namely Jacoco report generation and Sonar.
I would first try to simply generate Jacoco THEN I would look at why Sonar can not get a hold of them.
