 */
configurations {
  create("test")
}

tasks.register<Jar>("testJar") {
  dependsOn("testClasses")
  archiveBaseName.set("${project.name}-test")
  from(sourceSets["test"].output.classesDirs)
}

artifacts {
  add("test", tasks["testJar"])
}
  • in the module that depends on the test class
dependencies {
    testCompile(project(":project-name","test"))
}
