我想用proguard minifyEnabled进行发布版本，但这需要花费太多时间。构建仍然从昨天开始运行（差不多15个小时+）。
我添加了以下proguard规则：
-verbose
-optimizationpasses 3
-dontwarn com.androidquery.auth.**
-keep class com.androidquery.auth.**
-keep class com.google.android.exoplayer:exoplayer:r2.0.4
-keep class com.google.android.gms:play-services-gcm:9.6.1
-keep class com.google.android.gms:play-services-places:9.6.1
-keep class com.github.bumptech.glide:glide:3.5.2
-keep class com.squareup.picasso:picasso:2.+
-keep class com.yalantis:contextmenu:1.0.7
-keep class com.squareup:otto:1.3.8
-keep class com.nineoldandroids:library:2.4.0
-keep class com.squareup.retrofit2:converter-gson:2.1.0
-keep class com.squareup.retrofit2:retrofit:2.1.0
-keep class com.squareup.okhttp3:logging-interceptor:3.3.1
-keep class net.hockeyapp.android:HockeySDK:4.1.0-beta.2
-keep class com.android.support.**
-keep class com.squareup.okhttp:okhttp-urlconnection:2.2.0
-keep class com.squareup.okhttp:okhttp:2.2.0
-keep class com.squareup.picasso:picasso:2.4.0
请帮助，为什么需要这么多时间？
