我有一个使用ADT捆绑包在Eclipse中创建的Android项目。我想使用ProGuard导出发行版APK，但不断出现错误。
我知道这与Google Play服务库有关，因为当我从项目中删除它时，它会成功导出APK。
project.properties看起来像这样：
proguard.config=proguard-android.cfg
target=android-17
android.library.reference.1=../google-play-services_lib
proguard-android.cfg看起来像这样：
-libraryjars <java.home>/lib/rt.jar
-printmapping proguard-android.map
-dontwarn
-dontoptimize
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
我添加了keep类定义，因为在运行它时出现以下错误：
Proguard returned with error code 1. See console.
[2019-10-09 06:34:32 - AndroidApp] Proguard returned with error code 1. See console

关于错误的含义以及如何使它起作用，有人可以给我任何帮助吗？
