我正在创建一个Flutter应用程序。
现在我想添加Flutter OSM到项目中来使用Map。但是在添加flutter_osm_plugin到pubspec.yaml后，我得到了一个错误：

[!] Gradle threw an error while downloading artifacts from the network. Retrying to download...

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':flutter_osm_plugin'.
> Could not resolve all artifacts for configuration ':flutter_osm_plugin:classpath'.
   > Could not download kotlin-compiler-embeddable-1.5.21.jar (org.jetbrains.kotlin:kotlin-compiler-embeddable:1.5.21)

kotlin-compiler-embeddable-1.5.21.jar从浏览器下载。但我无法从Android Studio安装。我没有防病毒软件。

怎么了？多谢。
