New capability in Gradle 1.6. Run all verifications (e.g. checkstyle, tests) on all projects (if they are to be executed in this build) before uploading anything. e.g. ./gradlew clean build uploadArchives Will only upload after all projects have been built and tested.

gistfile1.groovy

allprojects {
  tasks.withType(Upload) {
    allprojects {
      mustRunAfter tasks.matching { it instanceof VerificationTask }
    }
  }
}
