【问题描述】:
是否可以使用默认的 Eclipse(Java EE 开发人员的 Eclipse IDE 或 Java 开发人员的 Eclipse IDE)来访问 java 类中的 scala 源代码?
我在 Scala 中访问 Java 代码没有问题,反之亦然,使用 Scala-IDE 而不是在默认的 eclipse 中。我可以使用以下 pom.xml 编译源代码并执行它。我的源文件夹结构是 src/main/java、src/main/scala、src/test/scala 和 src/test/java。这甚至可能还是我需要ScalaIDE?当我下载 ScalaIDE-Plugin for eclipse 并将 scala 性质添加到它正在工作的项目中时。
