我在 Eclipse 中将我的 scala 项目转换为使用 Maven（只需右键单击项目并配置 Maven 构建），这创建了 pom.xml，添加了正确的依赖项，从 Maven 存储库中提取所需的 jar，但每当我尝试编译时，我不会请参阅 target\classes 文件夹中生成的类文件。但是，我看到实际的源代码是 target\classes 文件夹下相应目录中的 scala 文件。我不确定为什么它要复制 target\classes 文件夹中的源文件。
另一个奇怪的事情是，如果我在 Eclipse 中打开单个 scala 文件并进行一些代码更改，那么它会自动构建该类文件，但是我有 1000 多个 scala 文件，所以不是一个可行的选择。
我尝试了所有选项，例如 Eclipse - Clean & Build，但没有任何效果，我什至尝试在 Eclipse 内使用 maven build，但它总是出现此消息“没有要编译的内容 - 所有类都是最新的”，我清理了我的目标目录，但仍然是一个问题。
我将不胜感激在这方面的任何帮助。
提前致谢
