在将我的scala sbt项目导入intellij时，我收到以下错误

Error while importing SBT project: ...

虽然从终端部署相同的应用程序到谷歌应用程序引擎我之后得到相同的错误，在终端我将APPENGINE_SDK_HOME设置为我的谷歌云安装目录/usr/lib/google-cloud-sdk/platform/google_appengine/。然后我得到以下错误。

那么如何设置APPENGINE_SDK_HOME以及哪个路径以便sbt appengineDeploy命令起作用。

我做了解决这个问题的步骤：

下载适用于Java的App Engine SDK： Google App Engine

Direct Download Link

无论您的GCloud安装路径如何，都要在计算机中解压缩。
设置APPENGINE_SDK_HOME：

export APPENGINE_SDK_HOME = /PATH/TO/SDK/appengine-java-sdk-1.9.54
下载示例Scala sbt应用程序。 Github Sample Scala App
运行sbt appengineDeploy命令来运行app。在Google云端将项目ID更改为您的项目ID。 Steps before running app

注意：

您无法在gae上安装mongodb等第三方数据库。
gae不支持akka框架。
gae不支持多线程。

将scala sbt部署到谷歌应用引擎
