Could not find commons-codec.jar in Android Studio 3.0

Question

I've installed Android Studio 3.0, once I open an app which ran perfectly on Android Studio 2.3.3, now when when I try building the app in Android Studio 3.0 it shows,

Error:Could not find commons-codec.jar (commons-codec:commons-codec:1.6). Searched in the following locations: file:/Applications/Android Studio.app/Contents/gradle/m2repository/commons-codec/commons-codec/1.6/commons-codec-1.6.jar

Help me resolve this issue.

Answer 2

It seems you missed adding maven repo to your build.gradle file.

   buildscript {
repositories {
    ...
    // You need to add the following repository to download the
    // new plugin.
    google()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0'
}
}
