当我尝试构建我的项目时出现此错误

错误：任务执行失败 ':app:transformClassesWithandroidGradleClassShrinkerForDebug'.

在收缩过程中发现警告，请使用-dontwarn 或-ignorewarnings 来抑制它们。

项目 build.gradle：

buildscript

        jcenter()
        maven  url 'https://maven.google.com'

task clean(type: Delete) 
    delete rootProject.buildDir

和 proguard-rules.pro

# Add project specific ProGuard rules here.
# By defaulto, the flags in this file are appended to flags specified
# in C:\Users\CM\AppData\Local\Android\Sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the javascript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview 
#   public *;
#

-keep class io.codetail.animation.arcanimator.**  *; 
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.AppGlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** 
  **[] $VALUES;
  public *;

问题

如何修改我的文件来解决这个问题？

【问题讨论】：

你需要在proguard-rules.pro的所有第三方库中添加-dontwarn或-ignorewarnings你可以在他们的docs/wiki页面上找到描述

@StanislavBondar 你能举例说明如何在 proguard 中编写这个吗？我以前没用过这个

您可以在这里找到解决方案：***.com/questions/47893266/…

【参考方案1】：

删除multiDexEnabled true、shrinkResources true、useProguard false 将minifyEnabled true 更改为minifyEnabled false

希望这会有所帮助。

【参考方案2】：

更改buildTypes->debug->minifyEnabled=false
