为什么我们需要的Maven或Ant的，如果我们已经有Eclipse的？ [英] Why do we need Maven or Ant, if we already have Eclipse?

问题描述

我觉得这个问题的延伸<一个href=\"http://stackoverflow.com/questions/7884809/compare-to-the-ide-for-java-do-we-still-need-ant\">Compare到IDE for Java中，我们还需要蚂蚁？

有以上问题的答案，但我想知道使用Maven或蚂蚁的一个具体例子。

当我在Eclipse开发，Eclipse中所做的一切对我来说，我只需要点击运行按钮。而且，Eclipse可以让您在code导出到一个可运行的罐子，甚至.EXE的窗口。

所以，我真的不知道为什么我需要的Maven或蚂蚁。

和也，如果我确实需要，哪一个我应该选择，Maven的蚂蚁还是？

解决方案

1. 因为你可能collegue preFER的NetBeans或IDEA


2. 由于设置可能会从一个日食变化安装到另一个


3. 因为你可能想自动获取你的依赖


4. 因为要自动运行完整的构建：构建，JAR，应用静态code分析，运行单元测试，生成的文件，拷贝到某个目录，调整某些性能取决于环境，等等


5. 因为一旦它的自动化，可以使用持续集成系统，它建立在每一个改变或每隔一小时申请，以确保一切仍在构建和测试仍然通过...

Eclipse是一个开发环境。但它不是一个构建工具。

我个人讨厌Maven的，但情况因人而异。有很多选择：gradle这个，buildr等

。

I think this question is an extension of Compare to the IDE for Java,do we still need Ant?

There are answers for the question above, but I wish to know an concrete example of using Maven or Ant.

When I develop in Eclipse, Eclipse does everything for me and I just need to click run button. And also, Eclipse can let you export your code to an runnable jar or even .exe for windows.

So I really don't know why I need Maven or Ant.

And also if I do need, which one should I choose, Maven or Ant?

解决方案

1. Because your collegue might prefer NetBeans or IDEA
2. Because the settings might vary from one eclipse install to another
3. Because you might want to get your dependencies automatically
4. Because you want to automate the complete build: build, jar, apply static code analysis, run the unit tests, generate the documentation, copy to some directory, tune some properties depending on the environment, etc.
5. Because once it's automated, you can use a continuous integration system which builds the application at each change or every hour to make sure everything still builds and the tests still pass...

Eclipse is a development environment. But it's not a build tool.

I personally hate Maven, but YMMV. There are many alternatives: gradle, buildr, etc.
