错误:任务’:app:transformClassesAndResourcesWithProguardForRelease的执行失败

我正在尝试签署我的应用程序以进行发布并且构建正确,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 { disable 'InvalidPackage' } packagingOptions { exclude 'META-INF/services/javax.annotation.processing.Processor' exclude 'META-INF/DEPENDENCIES.txt' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/NOTICE' exclude 'META-INF/LICENSE' exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/notice.txt' exclude 'META-INF/license.txt' exclude 'META-INF/dependencies.txt' exclude 'META-INF/LGPL2.1' } } repositories { mavenCentral() jcenter() maven { url 'https://esri.bintray.com/arcgis' } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile project(':StickyListHeaders') compile files('libs/org.apache.commons.io.jar') compile files('libs/json-20140107.jar') compile project(':ParallaxEverywhere') compile files('libs/nineoldandroids-2.4.0.jar') compile files('libs/gson-2.5.jar') compile project(':FlowLayout') compile 'com.android.support:design:23.2.0' compile 'com.android.support:appcompat-v7:23.2.0' compile 'com.jakewharton:butterknife:7.0.1' compile 'com.android.support:support-v4:23.2.0' compile 'com.android.support:recyclerview-v7:23.2.0' compile 'com.android.support:cardview-v7:23.2.0' compile 'com.esri.arcgis.android:arcgis-android:10.2.7' compile 'jp.wasabeef:blurry:1.0.5' compile 'com.github.bumptech.glide:glide:3.6.1' compile 'com.makeramen:roundedimageview:2.2.1' compile 'com.daimajia.easing:library:1.0.1@aar' compile 'com.daimajia.androidanimations:library:1.1.3@aar' compile 'org.apache.commons:commons-lang3:3.1' 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.* ; } -keepclasseswithmembernames class * { @butterknife.* ; } 

这是堆栈跟踪

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

谢谢

基于您获得的警告,我发现您依赖于依赖Java Runtime( rt.jar )部分但不属于Android运行时( android.jar )的库,因此您从ProGuard获得警告。

如果你的应用程序仍然可以使用所有这些组件,你可以配置ProGuard不要警告你这一点,所以在你的proguard配置文件(例如proguard-project.txt )中你可以尝试添加以下内容:

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

这应该可以帮助您解决构建中可能存在的任何额外警告:
