Scala,jar文件的问题 [英] Scala, problem with a jar file
问题描述
我没有经常使用java / scala,所以我的问题可能非常明显,但这里是:
I haven't worked with java/scala a lot, so my problem might be very obvious, but here it is:
我正在研究scala程序,我想从子目录中的.jar文件(filename.jar)导入。我认为这样可行:
I'm working on a scala program, and I want to import from a .jar file (filename.jar) in a sub-directory. I figure that this will work:
import sub.filename._
但我收到错误:对象文件名不是包子的成员。
But I get the error: "Object filename is not a member of package sub."
所以我尝试将jar文件移动到与scala程序相同的目录:
So I try simply moving the jar file to the same directory as the scala program:
import filename._
我得到:未找到:对象文件名
And I get: "not found: object filename"
我感谢任何帮助。
推荐答案
这不起作用。您从包中导入东西,而不是目录。如果您在某处有JAR,则需要使用 classpath 参数启动Scala,该参数指向您要访问的所有JAR。
That doesn't work. You import things from packages, not directories. If you have a JAR somewhere, you need to start Scala with the classpath parameter pointing to all JARs you want access to.
