在Gradle中启用minify以将apk缩小为释放模式后，我得到了
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.
Error:Execution failed for task ':ProjectName:transformClassesAndResourcesWithProguardForRelease'.
Job failed, see logs for details
Android插件版本2.2.3，Gradle版本2.14.1。
buildTypes {
release {
debuggable false
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
我的proguard-rules.txt如下：
-keep class com.wooplr.spotlight.** { *; }
-keep interface com.wooplr.spotlight.**
-keep enum com.wooplr.spotlight.**
-dontwarn javax.servlet.**
-dontwarn org.joda.time.**
-dontwarn org.w3c.dom.**

-dontwarn org.apache.commons.**
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.*
-dontwarn org.codehaus.jackson.**
