Gradle测试任务不会产生任何输出文件

Question

我一直致力于Ant to Gradle迁移，我的主要构建过程正常运行，现在正在进行测试编译和执行阶段，但是我遇到了测试编译任务的问题。 testClasses任务执行时没有错误，但是没有生成.class文件，就像testCompileJava任务无法找到所需的源目录或输出目录一样。  build.gradle如下：

//Build for XXXXX.com
apply plugin: 'java'

apply from: 'build-properties.gradle'

tasks.withType(JavaCompile) {
    sourceCompatibility = compile_source
    targetCompatibility = compile_target
 }


//SourceSets
sourceSets{
    main{
        java{
            srcDir     src_dir
            }
        }
    test{
        java{
            srcDirs test_src_dir
            }
            output.classesDir  test_dir
        }
}



task generate_scripts(type: GradleBuild){
    buildFile = 'build-db.gradle'
    tasks = ['generate_scripts']
}
task test_init(type: GradleBuild){
    buildFile = 'build-tests.gradle'
    tasks = ['test_init']
}


task init_build{
    description 'Initialises the build environment'
    init_build.mustRunAfter clean
    doFirst{
    mkdir ( build_dir)
    mkdir ( build_apps_dir)
    mkdir ( build_classes_dir)
    mkdir ( build_lib_dir)
    mkdir ( build_lib_license_dir)
    mkdir ( build_log_dir)
    mkdir ( build_javadoc_dir)
    }

    doLast{
    //Copy the web files (jsp, css images, web.xml, etc)
    copy {
        from ("${src_web_dir}/resources", exclude: '**/*.db' )
        into build_dir }
    copy {
        from src_web_inf_dir
        into build_web_inf_dir }
    copy {
        from config_dir + '/c3p0-config.xml'

    copy {
        from lib_dir + '/font'
        into build_classes_dir }

    //= copy server dependencies
    copy {
        from lib_compile_dir
        into build_lib_dir }
    copy {
        from lib_runtime_dir
        into build_lib_dir }

    // copy lib licenses
    copy {
        from lib_license_dir
        into build_lib_license_dir}
    }
}

task copyUpgradeScripts(dependsOn:[generate_scripts, init_build]){
    //        <!-- copy scripts to upgrade directories -->
            doFirst{

                    rename
                    {
                        String fileName -> "${mssql_upgrade_dir}/XXXXX-nodrop.sql"
                    }
                }
                into "${mssql_upgrade_dir}"
                }
