创建一个groovy工程（Create a Groovy Project）

Create a Groovy Project

To create a basic Groovy project in Eclipse perform the following steps:

    * Go to: File -> New -> Project
    * Select Java Project and press Next
    * In the Project Name field enter the name of your project (GroovyJava for this example)
    * Under Project Layout select Create separate source and output folders and press Finish
    * In the Package Explorer find the newly created project, right click, and select Groovy -> Add Groovy Nature

So far you should have a src folder, a bin-groovy folder, and several libraries. There is also a bin folder that was created by Eclipse, but is hidden due to

exclusion filters. The next steps are needed to make the bin-groovy folder the default output folder, and to connect it to the src folder so that the

debugger will know where to find the associated source and classes:

    * In the Package Explorer, right click on the "GroovyJava" project, and select: Build Path -> Configure Build Path
    * Select the Source tab and then use the Browse button to change the Default Output Folder from bin to bin-groovy
    * Press OK, OK

This will expose the bin folder in the Package Explorer. I'm not sure why the plugin creates a bin-groovy directory. Perhaps there are other "bin" files that

are best kept separate from the Groovy classes, or perhaps one of the original versions of Eclipse didn't create a "bin" directory automatically. Some day

when someone has a clear idea of the usefulness of this, or lack thereof, we can clean up my instructions.

创建一个groovy工程
为了在eclipse中创建一个基本的groovy工程你需要以下步骤：
*点击菜单File->New->Project
*选择java project然后点击next
*在工程名的字段（Project Name）中填写你的工程名（在这个例子中可以以GroovyJava命名）
*在工程布局器下选择创建独立源以及输出目录并点击结束（有些是英文啦，可能直接显示的就是finish）
*在Package Explorer(包浏览器)找到新建立的工程，点击右键，选择Groovy->Add ZGroovy Nature
到现在你应该有一个src文件夹，一个bin-groovy文件夹，以及几个lib库。当然还有一个被Ecllipse创建的bin文件夹，但它已经利用exclusino filters（Eclipse的排除过滤器）

隐藏起来了。接下来要让bin-groovy文件夹成为默认的输出文件夹，并且把bin-groovy与src文件夹连接起来以便调试器知道从哪儿找到关联的源文件和类：
*在Package Explorer(包浏览器)找到新建立的工程，点击右键选择Build Path->Configure Build Path
*选择Source选项卡利用Browse button改变默认的输出文件夹为bin-groovy，原来可是bin文件夹哟
*然后就是点击 OK OK
这些工作做完后原来隐藏的bin文件夹将为出现在Package Explorer(包浏览器)。我不知道为什么groovy的插件要建立一个bin-groovy 的文件夹。或许有其它的"bin"文件夹里的文

件要和Groovy的类文件分开？也可能在Eclipse的早期版本不提供"bin"文件夹的自动建立？如果有人清楚这种做法的原因我们可能一起完善我的这人操作指南。
