使用Gradle Copy任務從所有依賴項復制META-INF

Question

使用Gradle Copy任務的問題：

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);
        }
    }
}

非常簡單，遍歷所有依賴項（如果它們是歸檔文件），遍歷其zipTree，以確保它們本身沒有Jar。

完成此操作后，我想將META-INF文件夾中的所有文件復制到我的目錄中。

由於某種原因，它將所有文件復制到目錄中。 但是，如果我在每個文件中都使用println，則它僅顯示要復制的文件。

那是每個文件的輸出。 但是所有文件都進入libs文件夾...什么！？

該腳本的用法：復制所有meta-inf文件（最終只是許可和通知信息），並將它們添加到我自己的文件夾中的AAR文件中，以允許其他希望包含我的aar這樣做的用戶而不會出現文件沖突的問題： Android Gradle插件0.7.0：“ APK打包期間重復文件”

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+"/"
            }
        }
    }
}
