Question

我尝试使用sbt：https://mvnrepository.com/artifact/jep/jep/2.24

将jep（https://github.com/shadaj/scalapy）的构建包含到此scala项目中

因此，我不想通过非托管依赖项手动构建jep，而是希望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"

build.sbt中的

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

当然，代码中的每个Jep外观都会出现错误。

我绝对不熟悉scala或sbt，我只是试图让它运行而不必使用非托管依赖项，即让它与平台无关。手动构建jep似乎与平台有关，正在创建的文件：

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

正确设置了依赖关系，但导入错误。

尝试

import org.nfunk.jep.JEP

代替。

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一个：http://sens.cse.msu.edu/Software/jep-2.23/doc/website/doc/doc_usage.htm

sbt没有找到托管依赖的类
