如何通过Proguard（Android项目）将外部.jar排除在混淆之外？

When I export android project with proguard.cfg, all referenced .jar files are obfuscated as well. How can I exclude some of that .jars from obfuscation?

当我用proguard.cfg导出android项目时,所有引用的.jar文件也会被混淆。如何从混淆中排除一些.jars?

3 个解决方案

#1

If you don't want to edit the Ant script, you can add -keep options to proguard.cfg for the classes in those external jars. For instance:

如果您不想编辑Ant脚本,可以为这些外部jar中的类添加-keep选项到proguard.cfg。例如:

-keep class othercode.** { *; }

Or with a regular expression containing a negator:

或者使用包含否定符的正则表达式:

-keep class !mycode.** { *; }

The standard Ant script will still merge all referenced jars in the single output jar though.

标准的Ant脚本仍将合并单个输出jar中的所有引用的jar。

In your config file, set up your jars as library jars instead of input jars. This leaves them untouched.

在配置文件中,将jar设置为库jar而不是输入jar。这使他们不受影响。

-libjars <path/to/jars>

#3

Using proguard maven plugin I do it like that

使用proguard maven插件我这样做

<inclusion>
   <groupId>foo.bar</groupId>
   <artifactId>foo-bar</artifactId>
   <library>true</library>
   <filter>!META-INF/**</filter>
</inclusion>

The

<library>true</library>

lead to the external jar merged into the final jar after the obfuscation. But this might lead to the Manifest being overwritten. I haven't figured out yet how to avoid that the best way.

混淆后导致外部jar合并到最后一个jar中。但这可能会导致Manifest被覆盖。我还没想出如何避免这种最好的方法。
