Sorry because i was newbie in java i dont know how to solve simple problem like this. After searching for a week im already found how to solve. The problem is my jar contain same class in same directory this why i got this error. In my case, it was solved after i exclude which directory who cause this 

compile ('me.dm7.barcodescanner:zxing:1.9.3'){
        exclude group: 'com.google.zxing'
    }
