使用 gradle 复制任务从所有依赖项复制 META-INF

Question

使用 Gradle 复制任务时出现问题：

def loopJar(File file) {
    zipTree(file).findAll { that ->
        that
    }.collect { the ->
        if (the.getName().endsWith(".jar") || the.getName().endsWith(".aar")) {
            loopJar(the)
        }
        the;
    }
}

task fatJar(type: Copy) {
    into 'libs'
    include { it.toString().contains("META-INF") }
    from {
        configurations.compile.findAll {
            it.getName() != 'android.jar'
        }.collect {
            loopJar(it);
        }
    }
}

很简单，遍历所有依赖项，如果它们是存档，则遍历它们的 zipTrees 以确保它们本身没有 Jar。

完成此操作后，我想将 META-INF 文件夹中的所有文件复制到我的目录中。

出于某种原因，它正在将所有文件复制到目录中。但是，如果我在每个文件中打印ln，它只会显示我要复制的文件。

这是每个文件的输出。然而所有文件都进入了 libs 文件夹...什么！？

本脚本的用法：复制所有 meta-inf 文件（最终只是许可，注意信息）并将它们添加到我的 AAR 文件中它们自己的文件夹中，以允许其他希望包含我的 aar 的人这样做而不会出现文件冲突问题： Android Gradle plugin 0.7.0: "duplicate files during packaging of APK"

Answer 1

def loopJar(files, Map l) {
    files.findAll {
        if (!(it instanceof File))
            return false;
        it.getName() != 'android.jar'
    }.collect { file ->
        List e = new ArrayList();
        zipTree(file).each { the ->
            if (the.getName().endsWith(".jar") || the.getName().endsWith(".aar")) {
                loopJar(the, l)
            }
            if (the.getPath().contains("META-INF"))
                e.add(the);
        }
        if(!e.isEmpty())
        l.put(file.getName(), e);
    }
}

task fatJar << {
    Map l = new HashMap();
    loopJar(configurations.compile, l);
    l.each { key,val ->
        val.each {
            copy {
                from val
                into "licensing/"+key+"/"
            }
        }
    }
}

足够简单的修复：写成 Java 的方式。
