D8：程序类型已经存在：com.google.protobuf.AbstractMessageLite$Builder$LimitedInputStream

Question

我在我的 flutter 项目中收到以下错误并且不知道如何解决它错误：

D8: Program type already present: com.google.protobuf.AbstractMessageLite$Builder$LimitedInputStream

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.

build.gradle

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

我已经尝试升级所有内容。 也尝试通过现有的可用相关答案解决它，但对我没有任何帮助。 还检查了 protobuf 没有两个类。 尝试删除构建，.gradle 文件

好的，如果有人遇到同样的问题，我解决了这个问题，那么您必须检查以下内容

1. 所有依赖项都已更新
2. multiDexEnabled true

如果上面没有解决问题然后检查是否有重复的依赖如果你找不到任何重复的依赖然后尝试一个一个删除依赖然后再次运行应用程序这将需要一些时间但是一旦导致错误你的应用程序就会运行依赖被移除

谢谢，希望有用
