sbt 没有找到托管依赖的类

Question

我尝试使用 sbt 将 jep (https://mvnrepository.com/artifact/jep/jep/2.24) 的构建包含到这个 scala 项目中：https://github.com/shadaj/scalapy

因此，我不想通过非托管依赖项手动构建 jep，而是将其作为托管依赖项包含在内。因此我只包括：

resolvers += "jep" at "https://mvnrepository.com/artifact/"

libraryDependencies += "jep" % "jep" % "2.24" 

在 build.sbt 中

.jar 正在下载并包含在我的 .ivy2 文件夹中，但是在编译时，sbt 似乎找不到它：

当然，代码中每次出现 Jep 都会出现错误。

我对 scala 或 sbt 完全不熟悉，我只是想让它运行而不必使用非托管依赖项，即让它独立于平台。手动构建 jep 似乎取决于正在创建的文件的平台：

如果构建成功，它将创建一个目录 jep/build 包含一个 jep.jar 和 Jep 的编译 C 库，通常命名为 jep.so 或 jep.dll 取决于您的平台。

Answer 1

依赖设置正确，但导入错误。

试试

import org.nfunk.jep.JEP

改为。

实际上，我刚刚意识到这可能是两个不同的项目。您包含的依赖项是这个：http://sens.cse.msu.edu/Software/jep-2.23/doc/website/doc/doc_usage.htm
