找不到方法com.Android工具。r8.Version。getVersionString（）Ljava/lang/String；'

Question

我已经将我的android studio更新为3.4。我在进行发布构建时出错。

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.

我已经更新了gradle中的依赖项这是我的gradle文件

我没有使用kotlin。我检查了下面的各种资源，但没有一个有效

Answer 1

我解决了它。从android studio 3.4 R8版本控制添加到android studio中。所以我在我的构建中做了一些更改。gradle文件和gradle。属性文件

在我的应用程序级别build.gradle文件在发布部分我添加了一行

useProguard false

android.enableR8=true

因此，它将使用R8版本控制来创建我的APK。

如果您不想使用R8版本控制并想继续使用proguard，那么

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

希望这能帮助别人

Answer 2

问题是，您对R8 1.3.52有固定版本依赖：

classpath ('com.android.tools:r8:1.3.52' ) { transitive false }

和com.Android工具。r8.版本方法

public String getVersionString()

仅在R8 1.4及以上版本中存在。

我假设您使用的是固定版本的R8，因为该版本中存在错误修复。但是，这也应该在最新版本中得到修复，因此我建议您删除固定的R8版本依赖项并使用Android Studio附带的内容。
