spring - Maven 基于文本的工具是像 Ant 吗？

Question

我是 Spring 的新手，我正在寻找一种解决方案来帮助我在我的项目中填充 Spring 的依赖项。所以我在这个 question 中按照其他人的建议遇到了 Maven。 .我正在努力学习它。

我发现它并没有提供与 Eclispe 集成的简单方法。虽然官方网站确实给出了一些关于 eclipse 集成的提示，但它并没有多大帮助。该站点的大部分提示都是命令行，应该在 shell 中执行。

我发现 Spring Tool Suite 已经为我们在 Eclipse 中集成了 Maven。我试着给它做一个 pom.xml，发现我可以用 Maven 构建它:



我选择了“安装”并成功完成。但是这个项目仍然有很多红十字会:



它实际上在做什么？

这是我的 pom.xml，它有 spring.core 和 spring.context:

看完你的问题，我找不到与你的标题有任何关系。

无论如何，您可以尝试右键单击您的项目，然后选择 Maven -> Update Dependencies或 Update Project Configuration .有时项目中的更改(尤其是手动更改)需要手动刷新以使 M2E 插件知道您的更改并为您同步 Eclipse 项目。

这样的问题会导致 maven install 工作(因为它直接从 POM 读取并执行构建)，但 Eclipse 不会(因为它基于 M2E 插件生成的 Eclipse 项目构建)
