我有Thrift客戶端庫，並且很少在我的應用項目中生成thrift java類。需要幫助瞭解爲什麼未使用的Thrift客戶端庫和生成的類未被Proguard剝離。找到某些類未被Proguard刪除的原因
我已確認代碼縮水啓用
minifyEnabled true
proguardFiles file('proguard-android.txt')
我完全我的應用程序裏面註釋掉節儉使用。[早些時候在我的代碼，我只使用一個與互助儲蓄TDeserializer和TSerializer類生成的類和期待Proguard不保留TServer等類，因爲它們沒有被使用。但我注意到它仍然存在。爲了確保它不是間接保留Thrift客戶端類的生成類，我沒有評論這一切]
即使沒有人實際上在我的應用代碼中調用com.test.thrift.Task，seeds.txt仍然顯示出來e com.test.thrift.Task裏面。
我試圖調試爲什麼類沒有被刪除：
使用
它顯示-verbose
-whyareyoukeeping class com.offerup.android.thrift.Task { public * ; }
唯一的事情就是com.offerup.android.thrift.Task 通過在一個指令保持組態。
我試圖刪除一些候選人，如下圖。似乎沒有任何區別。除了蠻力的方式去除所有東西並且弄清楚配置條款，還有更好的方法來知道爲什麼這些類被保存了嗎？
