Gradle复制任务的包含和排除规范

Question

我有一个包含一组内容的复制任务

    task test_init(dependsOn: generate_scripts){

    doFirst{
        mkdir (project.test_dir)
        mkdir (project.test_data_dir)
        mkdir (project.test_reports_dir)
        mkdir (project.test_logs_dir)
        mkdir (project.test_jasper_dir)
        mkdir (project.test_chart_dir)
    }

    doLast{
        copy
        {
            from"${test_script_hsqldb_nd}"
            into"${test_dir}"
        }
        copy
        {
            from"${test_script_create_constraints}"
            into"${test_dir}"
        }
        copy
        {
            from"${test_script_drop_constraints}"
            into"${test_dir}"
        }

        copy
        {
            from fileTree(dir: "${test_src_dir}",
            include:
            [
                '**/*.xml',
                '**/*.dtd',
                '**/*.csv',
                '**/*.mpp',
                '**/*.dic',
                '**/*.png',
                '**/*.properties'
            ])
            into"${build_classes_dir}"


        }
    }

//////THIS IS MY UGLY WORKAROUND////////////////////
    doLast{
        delete "${build_classes_dir}/com/XXXX/ppm/gantt"
        delete "${build_classes_dir}/com/XXXX/ppm/util"
        delete "${build_classes_dir}/com/XXXX/ppm/action/pageinformation"
    }
}

它运行正常和花花公子,但是最后一个复制任务的"从"树中包含3个文件夹,这些文件夹不包含任何与包含相关的文件,因此在它们为空的任务之后.我想让他们完全被排除在任务之外,但我遇到了麻烦.目前我只是在最终的'doLast'块中删除它们,这似乎有点愚蠢.我试过了

exclude: "${test_src_dir}/com/XXXX/ppm/gantt",..**similar statements for other files**

和

exclude: "${test_src_dir}/**/gantt"

虽然我有一种感觉,'**'在这种情况下使用不正确.我很感激人们的任何投入.

你可以尝试includeEmptyDirs = false,虽然我不完全确定它是否适用于非空目录,只有在尊重包含/排除后才会变空.

PS:使用Copy任务通常更好(还显示了如何简化语法):

task test_init(type: Copy, dependsOn: generate_scripts) { 
    from test_script_hsqldb_nd
    from test_script_create_constraints
    from test_script_drop_constraints
    into test_dir
}

// assuming build_classes_dir is not a subdirectory of test_dir, we need a
// second Copy task (every Copy task has a single top-level destination dir)
task test_init_2(type: Copy, dependsOn: generate_scripts) {  
    from test_src_dir
    into build_classes_dir
    include '**/*.xml'
    include '**/*.dtd'
    include '**/*.csv'
    include '**/*.mpp'
    include '**/*.dic'
    include '**/*.png'
    include '**/*.properties'
    includeEmptyDirs = false
}

无论是Copy任务和copy方法会自动创建目标目录.
