Proguard 不会在 ZipEntry 中保留包层次结构

Question

我使用混淆器混淆了我的代码。在代码中，我想使用以下代码从指定包中读取所有 classes。

    URL directoryURL = Thread.currentThread().getContextClassLoader()
            .getResource("com/test/ui/controller");

此代码无效，因为 proguard 创建的 jar 不保留包层次结构。我写了一个代码，从混淆的 jar.This 输出中读取条目。看到 class 包没有保存在 zip 文件中。所以 getResource() 不起作用。

com/test/ui/controller/a.class

com/test/ui/controller/c.class

com/test/ui/controller/b.class

com/test/ui/controller/d.class

当我运行使用未混淆的 jar 的相同代码时，这里是输出。包级别保持在 jar.Do 你知道我如何告诉 Proguard 通过保持包级别来创建 jar。

com/

com/test/

com/test/ui/

com/test/ui/控制器/

com/test/ui/controller/a.class

com/test/ui/controller/c.class

com/test/ui/controller/b.class

com/test/ui/controller/d.class

Answer 1

-keeppackagenames [package_filter]

Specifies not to obfuscate the given package names. The optional filter is a comma-separated list of package names. Package names can contain ?, *, and ** wildcards, and they can be preceded by the ! negator. Only applicable when obfuscating.

Answer 2

-keepdirectories 解决了我的问题。

Specifies the directories to be kept in the output jars (or aars, wars, ears, zips, apks, or directories). By default, directory entries are removed. This reduces the jar size, but it may break your program if the code tries to find them with constructs like "mypackage.MyClass.class.getResource("")". You'll then want to keep the directory corresponding to the package, "-keepdirectories mypackage". If the option is specified without a filter, all directories are kept. With a filter, only matching directories are kept. For instance, "-keepdirectories mydirectory" matches the specified directory, "-keepdirectories mydirectory/*" matches its immediate subdirectories, and "-keepdirectories mydirectory/**" matches all of its subdirectories.
