Android：shrinkResources 无法构建

Question

我正在尝试使用shrinkResources，但它在构建时失败了。当我不这样做时，我看不到任何问题shrinkResources。我有以下配置：

minifyEnabled true
shrinkResources true

渐变版本

classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'net.sf.proguard:proguard-gradle:5.3.3' 

and

distributionUrl=https\://services.gradle.org/distributions/gradle-3.5-all.zip

。

我还看到很多人都面临着同样的问题，并提出了一些推荐的解决方案，例如：

• 打开 minifyEnabled true 以便使用shrinkResources true，我已经这样做了。
• 有些人建议通过shrinkResources false 关闭收缩资源以构建应用程序，但我需要使用shrinkResources，因此它不适用于我。
• 有一些推荐/建议表明 gradle 插件有一个 bug，我应该使用插件版本 < 2.2，但目前我还不能使用。

如果社区有人帮助我，我将非常感激。

以下是我在 gradle 控制台中看到的日志：

Answer 1

对我来说它工作得很好。我在用

• 全局构建.gradle
  • 类路径'com.android.tools.build:gradle:2.3.1'
  • // 没有特殊的程序包含
• 本地应用程序/build.gradle
  • 收缩资源 true
  • minifyEnabled true

在proguard-rules.pro我有

###############
# I use proguard only to remove unused stuff and to keep the app small.
# I donot want to obfuscate (rename packages, classes, methods, ...) since this is open source
-dontobfuscate
-dontoptimize
-keepnames class ** { *; }
-keepnames interface ** { *; }
-keepnames enum ** { *; }

我想我在添加之前遇到了问题-dontoptimize
