Question

我有一个简单的Scala项目在Eclipse中运行没有任何问题，但是，当打包到.jar中时，我在运行它时会收到此异常：

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: scala.util.matching.Regex.replaceAllIn(Ljava/lang/CharSequence;Lscala/Function1;)Ljava/lang/String;

这里发生了什么？...

有问题的代码行，以及完整的堆栈如下。

这是违规行：

"alt=\"[^>]+\">".r.replaceAllIn(inputStr, {_.replace(">", "/>")})

完整筹码：

发现了什么错误，Eclipse正在使用scala-library.jar：

C:\eclipse\configuration\org.eclipse.osgi\bundles

由于某种原因，我从Scala的安装文件夹复制的jar是不一样的。通过使用Eclipse正在使用的相同scala-library.jar 修复。

使用scala Regex类时的NoSuchMethod异常...困惑
