Remove file/jar/class from a gradle path in android studio

Question

I have multidex enabled and i am using org.apache.http.legacy.jar and added jumblr gradle path in my gradle file.I am getting exception

Error:Execution failed for task :app:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: org/apache/commons/codec/binary/Base64.class

I think this is because jumblr is also using the http legacy library so i think i need to explicitly remove http legacy library from jumblr gradle path. Kindly let me know on how to remove specific file/jar/class from a gradle path.

Answer 1

I think you can use exclude

compile('jumblr.jar') {
    transitive = true;
    exclude module: 'Base64';
}

OR

compile ('com.tumblr:jumblr:0.0.11') {
    transitive = true;
    exclude module: 'Base64';
}
