Ensime + sbt："Android未找到“

Question

我试图使用Ensime来处理使用g8 (https://github.com/philcali/android-plugin)生成的adnroid项目。遵循this question，我将android.jar添加到我的.ensime文件中。这就是：

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

此外，我在我的ANDROID_SDK_HOME ~/..bashrc文件中有一个导出的变量。但是当我试图启动时，我得到了这个错误：

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

我不明白为什么会发生这种事。有人对此有什么想法吗？谢谢。

找到解决办法了！答案在这里：https://github.com/aemoncannon/ensime/issues/184#issuecomment-2038002

.bashrc中的环境变量仅对运行在bash中或从bash启动的程序有效，否则需要.profile。如果使用emacs:可以使用M来查看emacs是否可以看到环境变量。在您的ANDROID_SDK_HOME中使用(setenv "ANDROID_SDK_HOME“)”~/_dev/_android/ANDROID_SDK_HOME_x86/“)为每个emacs会话设置它。但你可能已经知道了，所以我不知道这是否有任何帮助。Emacs有时似乎很难设置有关环境变量的内容。
