问题描述

尝试运行我的项目时出现此错误.

I'm getting this error when trying to run my project.

试图清除ivy2缓存没有成功.这就是我的构建sbt的样子:

tried to clear ivy2 cache with no success .this is how my build sbt looks like :

知道如何解决吗?

更新:java.class.path显示

UPDATE:java.class.path shows

推荐答案

这听起来像是类路径问题.您可能正在使用一个调用(使用)Typesafe Config的库，但是路径中Typesafe Config的版本小于1.3.0. Typesafe Config 1.3.0中引入了找不到的方法.要查看您的运行时类路径，请确保首先执行以下语句(即在您的应用崩溃之前):

It sounds like a classpath problem. You may be using a library that calls (uses) Typesafe Config, but the version of Typesafe Config in your path is less than 1.3.0. The method that is not found was introduced in Typesafe Config 1.3.0. To see your runtime classpath, make sure these statements are the first ones that are executed (i.e. before your app crashes):

val cp = System.getProperty("java.class.path")
val sep = System.getProperty("path.separator")
cp.split(sep).foreach(println)

一旦发现您没有Typesafe Config 1.3.0，请将其添加为显式依赖项.

Once you see that you do not have Typesafe Config 1.3.0, add it as an explicit dependency.
