android studio gradle dependencies 包存放在哪儿？

dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    compile PRoject(':social_sdk_library_project')    compile 'com.android.support:appcompat-v7:22.2.0'    compile 'com.github.chrisbanes.photoview:library:1.2.3'    compile 'com.android.support:support-v4:22.2.0'    compile 'com.jakewharton:butterknife:6.1.0'    compile 'com.networkbench.newlens.agent.android:nbs.newlens.agent:2.2.5'    compile 'com.google.zxing:core:3.2.0'    compile 'com.joanzapata.android:android-iconify:1.0.9'    compile 'com.loopj.android:android-async-http:1.4.8'}
