Flutter 插件开发之引入aar到安卓部分 并使用本地maven

flutter create -t plugin example_for_flutter_plugin_local_maven

mkdir android/aar
cd android/aar
wget https://github.com/Pgyer/mvn_repo_pgyer/blob/master/com/pgyersdk/sdk/3.0.9/sdk-3.0.9.aar?raw=true #下载
mv sdk-3.0.9.aar?raw=true sdk.aar #改名

mvn deploy:deploy-file -Dfile=sdk.aar -Durl="file://." # 这步会报错
