如何升级ProGuard for Android? [英] How to upgrade ProGuard for Android?

问题描述

我使用Android SDK Manager下载了最新版本的Android SDK.但是ProGuard尚未更新，仍为4.7版.

I used Android SDK Manager to download the latest version of Android SDK. But ProGuard was not updated and remained at version 4.7.

是否有必要从网站手动下载ProGuard并将其解压缩到\android-sdk\tools\proguard ?

Is it necessary to manually download ProGuard from its website and unzip it to \android-sdk\tools\proguard ?

还是Android SDK将始终使用4.7版? 4年就是这种方式.

Or will Android SDK always use Version 4.7? It has been this way for 4 years.

推荐答案

如今，ProGuard是Android Gradle插件的依赖项，通常会与其一起更新.查看./gradlew buildEnvironment的输出(自 2.10级)，您会看到类似

These days ProGuard is a dependency of the Android Gradle plugin, and is usually updated along with it. Looking at the output of ./gradlew buildEnvironment (supported since Gradle 2.10) you will see something like

classpath
+--- com.android.tools.build:gradle:2.2.3
|    \--- com.android.tools.build:gradle-core:2.2.3
...
|         +--- net.sf.proguard:proguard-gradle:5.2.1
|         |    \--- net.sf.proguard:proguard-base:5.2.1

如果您要使用的ProGuard版本不是Android Gradle插件所依赖的版本，则可以像这样覆盖它

If you want to use another ProGuard version than the one the Android Gradle plugin depends on you can override it like

buildscript {
    configurations.all {
        resolutionStrategy {
            // We want version 5.3.2 instead of 5.2.1.
            force 'net.sf.proguard:proguard-gradle:5.3.2'
        }
    }
}
