Question

我在eclipse和maven中使用scala项目时遇到错误，这是我从头开始构建的项目，当时工作正常。但是现在当我在一个月后打开它时它会显示错误，如图所示在截图中，即使我做mvn包它也会按预期生成jar文件，但是我看到我的所有类文件在每一行显示错误，如屏幕截图所示，可能是什么问题？

我使用scala版本：2.10.6并且附加在pom文件下面 scala.ide.org：提供者：scala-ide.org plugin-name：scala2.10 jar 版本; 4.4.1201605041056 pligin-id：org.scala-ide.scala210.jars
