【问题描述】：
在我的编译中，即使我将 twitter jar 文件放在 src/main/resources 文件夹中，但 SBT 编译并没有拾取它们并编译和打包没有错误，但在运行时给我错误，因为“找不到类 twitterUtils "
我的问题是为什么 SBT 没有在编译中包含资源文件夹中的 jar 文件？
人们告诉我要执行所有这些复杂的步骤来获取 Git 实用程序，然后执行我所做的 sbt 程序集，但是由于代理 Git 的 iam 无法正常工作，即使所有的 http_proxy 设置。 我还尝试将这些 twitter jar 文件放在 CLASSPATH 中，但没有成功。 我被这个问题困住了，所以非常感谢任何帮助。 请看下面的详细信息
