Ensime + sbt：「未找到Android SDK」

Question

我正在嘗試使用Ensime來處理與g8（https://github.com/philcali/android-plugin）生成的adnroid項目。跟着this question我將android.jar添加到我的.ensime文件中。下面是它：

(:project-package "org.test" 
:use-sbt t 
:compile-jars ("~/_dev/_android/android-sdk-linux_x86/platforms/android-8/android.jar")) 

而且我已經在我的〜/ .bashrc文件有一個出口ANDROID_SDK_HOME變量。 但是，當我試圖啓動ensime我得到這個錯誤：

java.lang.RuntimeException: Android SDK not found. You might need to set ANDROID_SDK_HOME or ANDROID_SDK_ROOT or ANDROID_HOME

我不明白爲什麼會發生的原因。有人對此有一些想法嗎？謝謝。

找到了解決方案！答案就在這裏：https://github.com/aemoncannon/ensime/issues/184#issuecomment-2038002：

The environment variables in .bashrc are only valid for programs running in or are started from bash, otherwise you'll need .profile. If you're using emacs: You could use M-x getenv to see if emacs can see the environment variable. Use a (setenv "ANDROID_SDK_HOME" "~/_dev/_android/android-sdk-linux_x86/") in your .emacs to set it for every emacs session. But you probably already know this so I don't know if this is of any help at all. Emacs sometimes seems to be tricky to set up concerning environment vars.
