Could not find method compile() for arguments [com.android.support:appcompat-v7:19.0.0] on root project

I have a simple ‘HelloWorld’ android app.

I installed gradle and added build.gradle file in my project with following dependency

dependencies {

compile ‘com.android.support:appcompat-v7:19.0.0’

compile fileTree(dir: ‘libs’, include: [’*.jar’]) }

But when running gradle build I get the following error Could not find method compile() for arguments [com.android.support:appcompat-v7:19.0.0] on root project ‘SampleApp’.

Can someone help me resolve this issue?

Thanks in advance!!
