打开一个现有的Java项目 [英] Opening an existing Java project

问题描述

有人可以帮助我使用Eclipse或Netbeans打开现有的Java项目吗？
这是SourceForge上的一个特定项目， SMPPClientServer 。

我想做的只是让这个项目运行。但是，这似乎是一个挑战，因为我完全是Java的新手（我是C＃.Net开发人员）。

解决方案

• 从sourceforge下载.jar，将其保存在PC上的某个位置。


• 打开eclipse。


• 您需要打开包资源管理器窗口 - 默认情况下应该打开我想在LHS上。


• 右键单击New - > Project，然后选择Java Project


• 点击下一步


• 给你的项目一个名字，基本上可以是任何东西，虽然有命名标准。例如MyProject


• 单击下一步，然后单击完成。


• 现在，您将在包资源管理器窗口中创建一个名为MyProject的项目。 >
  
• 现在，您需要将jar导入到项目中：


• 在项目中创建一个文件夹，您可以在其中保留任何jar。右键单击MyProject，新建 - >文件夹，并给它一个名称，说x-jars


• 此文件夹将在MyProject下创建。这是一个真正的（系统）文件夹，你想将你的jar复制到这个文件夹。该文件夹将位于您的文件系统上，位于〜eclipse-workspace / MyProject / x-jars /


• 复制到x-jars文件夹后，在eclipse中选择MyProject并点击F5刷新。这个jar现在会显示在你的x-jars文件夹下（你可以通过点击小三角形来扩展一个文件夹的内容）


• 现在你想要实际使用你的jar：


• 右键单击MyProject下的src（src是保存所有Java类的地方）。 Do New - > Package，并按照标准约定给出一个名称，如：com.mydomain.smpp，然后单击Finish。


• 右键单击生成的包，然后执行新建 - >类，给它一个名字，例如MyTest，然后单击完成。


• 您将在主eclipse编辑器中拥有一个Java类的框架。这个类生活在包com.mydomain.smpp中。所有类都应该包在一个包中。


• 最后，您需要确保x-jars文件夹包含在构建（编译）路径中。右键单击MyProject，执行构建路径 - >配置构建路径。在库选项卡上，单击添加JARS，然后在MyProject中选择x-jars文件夹。


• 就是这样。我不能帮你设置一个试用的SMPP应用程序/类，因为似乎没有任何文档或已发布的API，但这是您需要做的使用该jar。

Can someone help me to open an existing Java project using Eclipse or Netbeans? It's a specific project on SourceForge, SMPPClientServer.

All I want to do is to just get this project to run. But, this seems like a challenge at the moment as I'm totally new to Java (I'm a C#.Net developer).

解决方案

• Download the .jar from sourceforge, save it somewhere on your PC.
• Open eclipse.
• You need the "Package Explorer" window open - should be open by default I think, on the LHS.
• Right click, New -> Project, and select "Java Project"
• Click Next
• Give your project a name, can be basically anything, although there are naming standards. E.g MyProject
• Click Next, then click Finish.
• You'll now have a new project called MyProject in the Package Explorer window.
• Now you need to import the jar to your project:
• Create a folder in your project in which you'll keep any jars. Right click on "MyProject", New -> Folder and give it a name, say "x-jars"
• This folder will be created below MyProject. This is a real (system) folder, and you want to copy your jar into this folder. This folder will be located on your filesystem at ~eclipse-workspace/MyProject/x-jars/
• When copied into the x-jars folder, back in eclipse select MyProject and hit F5 to refresh. The jar will now show up under your x-jars folder (You can expand a folder contents by clicking the little triangles)
• Now you want to actually use your jar:
• Right click on "src" under MyProject (src is where you keep all your java classes). Do New -> Package, and per standard conventions give it a name like: com.mydomain.smpp and click Finish.
• Right Click on the resulting Package and do New -> Class, and give it a name, e.g MyTest, and click Finish.
• You'll now have the skeleton of a Java class in your main eclipse editor. This class lives in the Package com.mydomain.smpp. All classes should live in a package.
• Finally you need to make sure that the x-jars folder is included in your build (compile) path. Right click on MyProject, do Build Path -> Configure Build Path. On the Libraries tab click "Add JARS", and select the x-jars folder in MyProject.
• And that's it. I can't help you set up a trial SMPP app/class as there does not appear to be any docs or published API, but this is what you need to do to use the jar.
