You can create a merged report without merged exec file. Create a new task to the root of build.gradle with following content.

task jacocoReport(type: JacocoReport) {
    for (p in allprojects) {
        def testTask = p.tasks.findByName("test")
        if (testTask != null)
            dependsOn(testTask)

        executionData.setFrom(file("${p.buildDir}/jacoco/test.exec"))
        classDirectories.from(file("${p.buildDir}/classes/java/main"))
    }
}
