transformClassesAndResourcesWithProguardForRelease＆＃39; Android中的错误

Question

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。

有人可以帮我这个吗？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.

以下是完整的详细错误：http://justpaste.it/perror抱歉，我不得不将其作为链接，因为它很大。

以下是依赖项：

在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

您不必指定任何类似com.viewpagerindicator.**的套餐，这会取消所有警告，而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...

  Final number of library classes:    1317

Answer 2

在ProGuard文件中添加：

-dontwarn com.viewpagerindicator.**

如果您打开了自己提供的链接并搜索了大约三分之二的“警告”，则可以看到以下消息：

Warning:com.viewpagerindicator.LinePageIndicator: can't find referenced method 'float ceil(float)' in library class android.util.FloatMath

如果有任何警告ProGuard将停止并要求您先修复它们，或者如果您的代码有效，您可以选择dontwarn忽略它们。

更新05/01/2017

如果警告显示in program class，则编译的类文件很可能不一致，请尝试将它们全部删除并重建项目。

如果警告显示in library class，则编译的类文件与库不一致。尝试重新编译类文件或将库升级到一致的版本。

帮助我的是将所有依赖项更新到上一版本。

Answer 4

就我而言，proguard文件完全被忽略，因为该项目由几个模块组成。根据{{​​3}}，解决方案是在导致问题的模块的gradle中设置以下内容：

defaultConfig {
    consumerProguardFiles 'proguard-rules.txt'
}

这似乎包括应用程序的proguard中模块的程序。现在考虑我的dontwarn陈述。
