任务 ':app:transformClassesWithAndroidGradleClassShrinkerForDebug' 执行失败

Posted 2023-04-15

【中文标题】任务 \':app:transformClassesWithAndroidGradleClassShrinkerForDebug\' 执行失败

【英文标题】：Execution failed for task ':app:transformClassesWithAndroidGradleClassShrinkerForDebug'任务 ':app:transformClassesWithAndroidGradleClassShrinkerForDebug' 执行失败

【问题描述】：

我收到此错误是因为我试图通过引用此document 来减小我的 apk 大小

任务“:app:transformClassesWithandroidGradleClassShrinkerForDebug”执行失败。 收缩过程中发现的警告，请使用 -dontwarn 或 -ignorewarnings 来抑制它们。

buildTypes 
        debug 
            minifyEnabled true
            shrinkResources true
            useProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        
        release 
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        
    

如何使用-dontwarn or -ignorewarnings to suppress them？我必须在哪里添加这个键。

现在出现以下错误，如果我从 build.gradle 中删除 shrinkResources true 则不会出现任何错误。但是我需要使用shrinkResources来减小apk文件的大小，如何解决以下错误。

【参考方案1】：

使用以下配置

debug 
        minifyEnabled true
        shrinkResources true
        useProguard false
        ...
    

您尝试缩减禁用了ProGuard 的资源。而且由于资源缩减works only in conjunction with ProGuard 你得到

Removing unused resources requires unused code shrinking to be turned on.

以下配置应消除构建错误：

debug 
    minifyEnabled true
    shrinkResources true
    ...

如果之后你得到Warnings found during shrinking, please use -dontwarn or -ignorewarnings to suppress them，你需要编辑proguard-android.txt添加相应的-dontwarn <package_name_with_wildcard_or_class_name>。

【讨论】：

感谢您的回答，它现在已修复，我还添加了 -dontnote 用于一些抛出一些错误说明的包和类。
