One can run gradlew dependencies to learn about dependencies of module tasks. It there a way to find transitive dependencies of buildscript dependencies
Unfortunately there is no way to specify the build script configuration to the implicit dependencies task via the CLI. You'll have to explicitly define a task of type DependencyReportTask configured with your build script configuration.
task buildscriptDependencies(type: DependencyReportTask) {
configurations = [buildscript.configurations.classpath]
}
Update:
Beginning with Gradle 2.10 you can now get information on buildscript dependencies via
gradle buildEnvironment
