m2eclipse是否取消了多模块的支持？
与大多数 spring+hibernate 企业案例一样，我想将 Dao、Service、Web 层分离到不同的模块中，以便我可以在前端和管理网站中同时重用 Dao 层。问题是我发现 m2eclipse 不能很好地支持这个多模块项目，有什么解决方案吗？
我正在使用 eclipse 3.7 和 Sonatype m2eclipse，我有一个典型的多模块结构项目，一个抽象父模块，2 个子模块（A 和 B）。我可以从父级运行“package”，但是当我在 system.out 等任何对象后输入“点”时，我无法得到提示，并且它显示“此编译单元不在 Java 项目的构建路径上”。此外，在 A 的 pom.xml 中设置依赖项后，我无法从 B 调用 A 中的方法。
我在这里发现了一个非常类似的问题 问题在eclipse中运行maven项目，不被识别为Java项目，但这并不能解决我的问题。我听说 m2eclipse 已经删除了对多模块项目的支持，但这种需求非常普遍，我 100% 确定一定有某种解决方案。
谢谢。
我通过将整个项目和子模块也作为单独的项目导入来使其工作。我发现在个别项目中我可以获得提示提示方法并进行调试，但我使用整个项目的 pom 来构建。
Like in most spring+hibernate enterprise cases, I want to separate Dao, Service, Web layers into different modules, so that I can reuse Dao layer simultaneously in front-end and admin web site. The issue is I found m2eclipse does not support this multi-module project very well, any solutions?
I'm using eclipse 3.7 and Sonatype m2eclipse, I have a typical multiple-module structure project, one abstract parent, 2 children modules(A and B). I can run "package" from the parent, but I can not get hint when I input a "dot" after any object like system.out, and it says "This compilation unit is not on the build path of a Java project." Moreover, I can not invoke methods in A from B after I set dependencies in A's pom.xml.
I found a very similar issue here Issues with maven project running in eclipse, not recognized as Java project, but which does not solve my problem. I heard m2eclipse has removed this support for multiple-module project, but the need is so common that I'm 100% sure that there must be some kind of solution.
Thanks.
I got it working by importing the whole project and sub-module as individual projects as well. I find in individual projects I can get prompt hint methods and debug, but I'm using the whole project's pom to build.

m2e 中仍然支持多模块，我不知道您从哪里听说它已被删除，但这是完全错误的。
您只需将子模块导入为现有的 Maven 项目即可。

Multi-module is still supported in m2e, I don't know where you heard that was removed but that's utterly wrong.
You simply need to import your sub modules as existing maven projects.
