找不到com.android.databinding:编译器3.4.0
大家好，我们如何在android_plugin_version = '3.4.0‘中启用数据库？作为我的android，我安装了最新版本，当将android_plugin_version = '3.4.0‘降级到3.2.xx时，我收到了另一个错误。

}同步没有问题，但是当运行它时，我收到了这个错误。

您正在使用Databinding编译器的错误版本。对于最新版本，您可以查看像mvnrepository储存库这样的站点。目前的最新版本是3.4.0。在这里，您传递的是错误的版本：
kapt "com.android.databinding:compiler:$android_plugin_version"相反，请使用以下命令：
kapt "com.android.databinding:compiler:3.4.0"更新
在AndroidStudio3.3及以上版本中，您不需要添加注释处理器kapt "com.android.databinding:compiler:$android_plugin_version"。只需在模块gradle文件中设置dataBinding.enabled = true或如下所示：
android {
...
dataBinding {
enabled = true
}

我只需移除kapt "com.android.databinding:compiler$android_plugin_version“，它就能工作ActivityMainBinding出现在我的MainActivity中。
