java - 错误 :Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease

Question

我正在尝试签署我的应用程序以供发布并且它构建正确，但我想启用 Proguard 我收到以下错误

Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease

我的gradle文件

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions {

    }
}

    compile 'com.lifeofcoding:cacheutilslibrary:1.0.1@aar'
    compile 'com.edmodo:rangebar:1.0.0'

}

和我的 ProGuard 规则文件

    -keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }

-keepclasseswithmembernames class * {
    @butterknife.* <fields>;
}

-keepclasseswithmembernames class * {
    @butterknife.* <methods>;
}

这是堆栈跟踪

这个 Gdoc 包含我收到的所有警告 https://docs.google.com/document/d/1YxbOfqaUyHJivYrs1hkHE4Tmmo4xAP8-aJkUJJB8e-k/edit?usp=sharing

谢谢

根据您收到的警告，我发现您依赖于依赖于 Java 运行时部分 (rt.jar) 但不属于 Android 运行时 () 的库android.jar)，因此您会收到来自 ProGuard 的警告。

如果您的应用在缺少所有这些组件的情况下仍能正常工作，您可以配置 ProGuard 使其不对此发出警告，因此在您的混淆器配置文件(例如 proguard-project.txt)中，您可以尝试添加这些:

-dontwarn javax.servlet.**
-dontwarn org.joda.time.**
-dontwarn org.w3c.dom.**

这应该可以帮助您解决可能保留在您的构建中的任何额外警告:
