Maven 在使用测试范围时无法编译测试-类
Maven cant compile test-classes when using test scope
我目前正在尝试使用 MockBukkit 来测试我的 Minecraft 插件，并将其包含在我的带有测试范围的 pom 中，因为我只需要它。然而，问题是当使用测试范围时，依赖项出现在我的本地存储库中，但无法通过 eclipse 或 Maven 解决。
问题似乎是 compiler 插件的默认编译目标试图编译测试 类 即使它不能使用依赖项，因为它们只在测试阶段可用. （不过这只是我的猜测）。

好的，错误只是我不得不更改.class路径，因为我刚刚将默认的eclipse项目转换为Maven项目，所以我不得不删除Build Path中的默认src文件夹并添加不同的 Maven。没有它，Maven 会尝试将每个 class 作为正常编译，而不是作为使它们失败的测试。
如果有人感兴趣，这里是两个 .classpath 文件之间的比较：
