更新Scala Jar(Lang:Scala-Library:JAR:2.7.7)给出了例外

Question

我正在尝试更新org.scala-lang：scala-library：jar：2.7.7，从版本2.7.7到2.10.7，在我的项目中启动服务器时 -

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.sun.proxy.$Proxy171
    at sun.reflect.GeneratedConstructorAccessor126.newInstance(Unknown Source)
    at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source)

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1585)

如何解决这个问题？

请让我知道是否需要其他细节。

您不能仅像这样更新Scala运行时JAR：您的应用程序的任何依赖项都需要更新为2.10兼容的版本和Scala代码
