What is the use of including classpath in dependencies section of buildscript build.gradle(Project). Example :
buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.5.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } classpath 'com.android.tools.build:gradle:1.5.0' what is its purpose / what does it do?
