找不到方法'com.android.tools.r8.Version.getVersionString()Ljava/lang/String;' [英] Unable to find method 'com.android.tools.r8.Version.getVersionString()Ljava/lang/String;'

问题描述

我已将Android Studio更新为3.4. 进行发布版本时出现错误.

I have updated my android studio to 3.4. I am getting error while making release build.

Unable to find method 
'com.android.tools.r8.Version.getVersionString()Ljava/lang/String;'.
Possible causes for this unexpected error include:
Gradle's dependency cache may be corrupt (this sometimes occurs after 
a network connection timeout.)
Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt. Stopping 
all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)

Your project may be using a third-party plugin which is not compatible 
with the other plugins in the project or the version of Gradle 
requested by the project.

In the case of corrupt Gradle processes, you can also try closing the 
IDE and then killing all Java processes.

我在gradle中更新了我的依赖项 这是我的gradle文件

I have updated my dependencies in gradle Here is my gradle file

}

我不使用Kotlin. 我检查了如下所示的各种资源，但没有任何作用

I am not using kotlin. I checked various resources like below but none worked

java.lang.NoSuchMethodError-Ljava/lang/String;) Ljava/lang/String;

也尝试过 重新下载依赖项并同步项目 & 停止Gradle构建过程(需要重新启动) 但没有一个.

also tried with Re-download dependencies and sync project & Stop Gradle build processes (requires restart) but none worked.

项目级gradle文件

to all sub-projects/modules.

}


allprojects {

推荐答案

我解决了.从android studio 3.4开始，在android studio中添加了R8版本控制. 所以我在build.gradle文件和gradle.properties文件中做了一些更改

I solved it. From android studio 3.4 R8 versioning is added in android studio. So i did some changes in my build.gradle file and gradle.properties file

在发布部分的应用程序级别build.gradle文件中，我添加了一行

In my app level build.gradle file in release section I added one line

useProguard false

&在gradle.properties文件中

& in gradle.properties file

android.enableR8=true

因此它将使用R8版本创建我的APK.

so it will use R8 Versioning to create my APK.

如果您不想使用R8版本控制并希望继续使用proguard，请进行

Incase if you dont want to use R8 versioning and want to continue with proguard then make

 android.enableR8=false //in gradle.properties file
