Gradle: multi-project dependency graph (supports depth > 2)

dependency-report.gradle

// Inspired by https://gist.github.com/abesto/cdcdd38263eacf1cbb51
// Task creates a .dot file with all inter-module dependencies
// Supports any depth of nested modules

task moduleDependencyReport {
    doLast {
        def file = new File("project-dependencies.dot")
        file.delete()
        file << "digraph {\n"
        file << "splines=ortho\n"
        printDeps(file, rootProject)
        file << "}\n"
    }
}

// recursively print dependencies to file and move on to child projects 
def printDeps(file, project) {
    project.configurations.compile.dependencies
        .matching { it in ProjectDependency }
        .each { to -> file << ("\"${project.name}\" -> \"${to.name}\"\n")}

    project.childProjects.each { child -> printDeps(file, child.value) }
}

Thanks, but it is not working with new Android projects on gradle 4.4. If you need new android projects support try this one: https://gist.github.com/nikialeksey/7cefae6b3104ce9a2c765197343bc436
