Question

我正在尝试为我的应用程序配置proguard。一切正常，直到我在构建文件中启用minifyEnabled。之后说下面的错误：

Error:Execution failed for task ':app:shrinkReleaseMultiDexComponents'.
> java.io.IOException: The output jar [E:\androidStudioProjects\name\app\build\intermediates\multi-dex\release\componentClasses.jar] must be specified after an input jar, or it will be empty.

我的gradle文件是

apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.name.activity"
        minSdkVersion 13
        targetSdkVersion 22
        versionCode 29
        versionName "3.0.3"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:22.+'
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:7+'
    compile project(':googlemapssdkm4b_lib')
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.github.johnkil.android-robototextview:robototextview:2.4.0'
    compile 'com.android.support:recyclerview-v7:22.2.+'
    compile project(':volley')
    compile 'com.android.support:design:22.2.0'
    compile 'com.appyvet:materialrangebar:1.0'

}

我的proguard-rules.pro文件是

# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
#-dontoptimize
#-dontpreverify

# If you want to enable optimization, you should include the
# following:
-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
-optimizationpasses 5
-allowaccessmodification
#
# Note that you cannot just include these flags in your own
# configuration file; if you are including this file, optimization
# will be turned off. You'll need to either edit this file, or
# duplicate the contents of this file and remove the include of this
# file from your project's proguard.config path property.

请帮帮我..

我花了很长时间才弄明白，但正如我猜测的那样，这完全是关于Proguard的配置。

我开始深入研究控制台中的警告并意识到Proguard无法找到某些参考文献。因此，将它们作为-dontwarn添加到proguard配置文件中解决了这个问题。

就我而言，我不得不忽略下面的包裹;

-dontwarn java.lang.invoke**
-dontwarn org.apache.lang.**
-dontwarn org.apache.commons.**
-dontwarn com.nhaarman.**
-dontwarn se.emilsjolander.**

无法为android配置proguard
