Handling multi project builds with Grade, Jacoco and Sonarqube - gradle

Question

This is working so far (at least it looks like it works), but I don't feel that it is idiomatic or would stand the test of time even for a few months. Is there any way to do it better or more "by the book"?
We have a few multi project builds in Gradle where a project's test could touch another one's code, so it is important to see the coverage even if it wasn't in the same project, but it was in the same multiproject. I might be solving non existing problems, but in earlier SonarQube versions I had to "jacocoMerge" coverage results.
jacocoTestReport {
reports {
executionData (tasks.withType(Test).findAll { it.state.upToDate || it.state.executed })
xml.enabled true
}
}
if(!project.ext.has('jacocoXmlReportPathsForSonar')) {
project.ext.set('jacocoXmlReportPathsForSonar', [] as Set<File>)
}
task setJacocoXmlReportPaths {
dependsOn('jacocoTestReport')
doLast {
project.sonarqube {
properties {
property 'sonar.coverage.jacoco.xmlReportPaths', project.
ext.
jacocoXmlReportPathsForSonar.
findAll { d -> d.exists() }.
collect{ f -> f.path}.
join(',')
}
}
}
}
project.rootProject.tasks.getByName('sonarqube').dependsOn(setJacocoXmlReportPaths)
sonarqube {
properties {
property "sonar.java.coveragePlugin", "jacoco"
property "sonar.tests", []
property "sonar.junit.reportPaths", []
}
}
afterEvaluate { Project evaldProject ->
JacocoReport jacocoTestReportTask = (JacocoReport) evaldProject.tasks.getByName('jacocoTestReport')
evaldProject.ext.jacocoXmlReportPathsForSonar += jacocoTestReportTask.reports.xml.destination
Set<Project> dependentProjects = [] as Set<Project>
List<String> configsToCheck = [
'Runtime',
'RuntimeOnly',
'RuntimeClasspath',
'Compile',
'CompileClasspath',
'CompileOnly',
'Implementation'
]
evaldProject.tasks.withType(Test).findAll{ it.state.upToDate || it.state.executed }.each { Test task ->
logger.debug "JACOCO ${evaldProject.path} test task: ${task.path}"
sonarqube {
properties {
properties["sonar.junit.reportPaths"] += task.reports.junitXml.destination.path
properties["sonar.tests"] += task.testClassesDirs.findAll { d -> d.exists() }
}
}
configsToCheck.each { c ->
try {
Configuration cfg = evaldProject.configurations.getByName("${task.name}${c}")
logger.debug "JACOCO ${evaldProject.path} process config: ${cfg.name}"
def projectDependencies = cfg.getAllDependencies().withType(ProjectDependency.class)
projectDependencies.each { projectDependency ->
Project depProj = projectDependency.dependencyProject
dependentProjects.add(depProj)
}
} catch (UnknownConfigurationException uc) {
logger.debug("JACOCO ${evaldProject.path} unknown configuration: ${task.name}Runtime", uc)
}
}
}
dependentProjects.each { p ->
p.plugins.withType(JacocoPlugin) {
if (!p.ext.has('jacocoXmlReportPathsForSonar')) {
p.ext.set('jacocoXmlReportPathsForSonar', [] as Set<File>)
}
p.ext.jacocoXmlReportPathsForSonar += jacocoTestReportTask.reports.xml.destination
JacocoReport dependentJacocoTestReportTask = (JacocoReport) p.tasks.getByName('jacocoTestReport')
dependentJacocoTestReportTask.dependsOn(jacocoTestReportTask)
setJacocoXmlReportPaths.dependsOn(dependentJacocoTestReportTask)
}
}
