Question

我已将Android Studio更新为3.4。进行发布版本时出现错误。

usercount

我在gradle中更新了我的依赖项这是我的gradle文件

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.

我不使用Kotlin。我检查了如下所示的各种资源，但没有用

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

Android Studio 3.0 - Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List'

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

Answer 1

问题是您对R8 1.3.52有固定的版本依赖性：

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

还有com.android.tools.r8.Version方法

public String getVersionString()

仅在R8 1.4和更高版本中存在。

由于该版本中的错误修复，我假设您使用的是R8的固定版本。但是，该问题也应该在最新版本中修复，因此我建议您删除固定的R8版本依赖性，并使用Android Studio随附的软件。

Answer 2

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

在发布部分的应用程序级别build.gradle文件中，我添加了一行

useProguard false

＆在gradle.properties文件中

android.enableR8=true

因此它将使用R8版本创建我的APK。

如果您不想使用R8版本控制并且想继续使用proguard，请进行

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

希望这会对某人有所帮助

找不到方法'com.android.tools.r8.Version.getVersionString（）Ljava / lang / String;'
