try lot of solution like delete BuildConfig file etc but without luck. After lot of googling i just understand, problem related to multiple dependencies file but unable to solve.

Also try command gradle -q dependencies but fail with this error

FAILURE: Build aborted because of an internal error.

• What went wrong: Build aborted because of an unexpected internal error. Please file an issue at: http://forums.gradle.org.

Also i like to mention i am try to migrate my project from eclipse and its build successfully when run Build->Rebuild Project in Android Studio

i know some dependencies are multiple in box library like

compile files('libs/commons-io-2.3.jar') compile files('libs/commons-lang-2.6.jar')

but if i am try to remove these than face exception

Error:(6, 29) error: package org.apache.commons.io does not exist
Error:(80, 13) error: cannot find symbol variable IOUtils
Error:(6, 32) error: cannot find symbol class CharEncoding
Error:(57, 75) error: cannot find symbol variable CharEncoding
Error:(58, 79) error: cannot find symbol variable CharEncoding etc...

Thanks for any suggestion

Answer 1

after lot of trials

dexOptions {
    preDexLibraries = false
    javaMaxHeapSize "4g"
}

this worked for me..
