java.lang.NoSuchMethodError: org.apache.commons.logging.LogFactory

When I enabing proguard for android, the proguard will obfuscate all the jars that include in the application. These jars include:

• libraryjars lib/Analytics_Android_SDK_2.1.jar
• libraryjars lib/commons-codec.jar
• libraryjars lib/commons-httpclient-3.1.jar
• libraryjars lib/commons-logging-1.1.jar
• libraryjars lib/weibo.jar
• libraryjars lib/signpost-core-1.2.1.1.jar
• libraryjars lib/signpost-commonshttp4-1.2.1.1.jar
• libraryjars lib/youmibannerad-android.jar

while building the signed jar I get the following dump:

In fact this project is about sina weibo SDK, when I use proguard to obfuscate it, I always fail, with the error below:

so I added the code -ignorewarnings into proguard config file, so the warnings all dismissed, but when I run the application, The errors that in the title will happened.

Ran into the same problem on an outsourced project where it seems the developers have used every possible free library in the world.

The safest approach is to supply ProGuard with the original libraries as a reference, even though some of them are deprecated and probably will never be called by your code:

Log4J - http://logging.apache.org/log4j/1.2/download.html

Avalon - http://www.docjar.com/jar_detail/avalon-framework-4.2.0.jar.html

Avalon LogKit - http://www.jarfinder.com/index.php/jars/versionInfo/17610

J2EE reference - http://www.jarfinder.com/index.php/jars/versionInfo/4598

Once you download all of the jars, point ProGuard to them:

# Apache commomns-logging fun

-libraryjars proguard_ref_lib/log4j-1.2.17.jar
-libraryjars proguard_ref_lib/avalon-framework-4.2.0.jar
-libraryjars proguard_ref_lib/avalon-logkit-2.2.1.jar
-libraryjars proguard_ref_lib/servlet-api-6.0.16.jar

# Apache commomns-logging fun ends

Enjoy

I would try commons-logging-1.1.1. It seems there's a version mismatch
