Proguard 返回错误代码 1。请参阅控制台 java.io.IOException

Question

从 Eclipse IDE 导出我的 Android 应用程序时，我收到如下错误：

Proguard returned with error code 1. See console
Warning: library class android.net.http.AndroidHttpClient extends or implements program class org.apache.http.client.HttpClient
       You should check if you need to specify additional program jars.
Warning: there were 1 instances of library classes depending on program classes.
          You must avoid such dependencies, since the program classes will
          be processed, while the library classes will remain unchanged.
java.io.IOException: Please correct the above warnings first.

-dontwarn com.google.android.gms.**
-dontwarn javax.jdo.**
-dontwarn com.google.api.client.googleapis.extensions.android.gms.**
-dontwarn org.apache.commons.**
-dontwarn org.ietf.jgss.**
-dontnote

我在 proguard confing 文件中添加了 dontwarn 和 dontnote 语句，我解决了一些警告但无法解决剩余的问题。请帮我解决这个问题。谢谢。

Answer 1

我也遇到过这个问题。清理项目并再次导出应该可以解决此问题。

Answer 2

将此添加到您的 proguard-project 文件中：

  -keep class org.apache.http.** { *; }
  -dontwarn org.apache.http.*

如果仍然存在错误，则返回。

Answer 3

您只需将以下代码添加到项目的 proguard-project.txt 文件中。

-dontwarn ["error package name or Error file path here"]

例如：

-dontwarn com.example.media.*

如果你有更多（疯狂的）错误出现，那么只需添加

-dontskipnonpubliclibraryclassmembers

这可能对你有帮助。

Answer 4

由于问题是由于库类android.net.http.AndroidHttpClient 和org.apache.http.client.HttpClient，我将两个库类的 -dontwarn 语句添加到 proguard-project 文件中。我补充的是：

-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.*
-dontwarn android.net.http.*

我已经完成了。感谢大家对此提供帮助。

Answer 5

请在下面给出的代码之前使用 cmets proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt:proguard-google-api-client.txt

在 project.properties 文件中
