您好，我正在努力为我的项目创建发布版本。我已经通过 SO/Google 帮助在 Progaurd 上尝试了很多东西，但我仍然无法创建发布版本。

有人可以帮我解决这个问题吗？我总是遇到这个问题:

Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
> java.io.IOException: Please correct the above warnings first.

这是完整的详细错误:http://justpaste.it/perror对不起，我不得不把它作为一个链接，因为它很大。

这里是依赖:

最佳答案

在您的 ProGuard 文件中添加:

-ignorewarnings

喜欢:

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\Softwares\Developing\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 *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile


-ignorewarnings

您不必像 com.viewpagerindicator.** 那样指定任何包，这将抑制所有警告，Gradle Console 只会说:

......
Warning: there were 4 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning: there were 2 unresolved references to library class members.
         You probably need to update the library versions.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember)

Note: you're ignoring all warnings! 
Ignoring unused library classes...
  Original number of library classes: 4237
  Final number of library classes:    1317
Printing kept classes, fields, and methods...
Shrinking...
