Difference among mavenCentral(), jCenter() and mavenLocal()? : <p>Actually, I am studying on <code>build.gradle</code> file. In some cases, I got that sometimes they are using <code>mavenCentral()</code>, <code>jCenter()</code> and <code>mavenLocal()</code> in repositories section. Sometimes they also using URL. So some question arises in my mind?</p>
