Proguard returned with error code 1. See console java.io.IOException

Question

While exporting my Android Application from Eclipse IDE, I am getting errors as below:

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.

You Just need to add below code to your project's proguard-project.txt file.

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

example as :

-dontwarn com.example.media.*

and if you have more(insane) errors coming, then just add

-dontskipnonpubliclibraryclassmembers

May be this helpful for you.

Add this to Your proguard-project file:

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

Then come back if still errors exists.

Getting `proguard.ParseException: Expecting java type before ';'` error on line ` -keep class org.apache.http.** { ; }` – AndyN Feb 18 '15 at 09:36
Solved the parseException error by replacing `;` with `*;` but again getting same error as in question. – AndyN Feb 18 '15 at 09:44
also after clean project? – Opiatefuchs Feb 18 '15 at 09:57

I also have faced this problem. Cleaning the project and exporting again should fix this.

As the issue was due to library class android.net.http.AndroidHttpClient and org.apache.http.client.HttpClient, I added -dontwarn statements for both the library classes to proguard-project file. what I added is:

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

and I am done. Thank you all for helping out on this.
