Eclipse 3.4 GWT 1.6 项目 - 如何从其他项目引用源代码? [英] Eclipse 3.4 GWT 1.6 project - how to reference source from other projects?

问题描述

我在 Eclipse 3.4 中有一个 GWT 1.6 项目，我正在尝试从我的工作区中的另一个(非 GWT)项目引用源代码.我已将该项目添加到我的构建路径，但我无法在托管模式下运行该应用程序.当我这样做时，我收到没有可用的源代码"错误.

I've got a GWT 1.6 project in Eclipse 3.4 and am trying to reference source from another (non-GWT) project in my workspace. I've added the project to my build path, but I can't run the application in hosted mode. When I do, I get a "no source code is available" error.

我进行了一些搜索和阅读，并尝试了其他人建议的一些方法(包括从依赖项目创建一个 jar 并链接到它)，但坦率地说，没有任何效果.

I've done some searching and reading and have tried a few things that others have suggested (including creating a jar from the dependent project and linking to it), but frankly nothing has worked.

如果你真的这样做了，你能帮我做一个简单的分步设置吗?我真的很感激，谢谢！

If you're actually doing this, could you please help me out with a simple step-by-step setup? I'd really appreciate it, thanks!

推荐答案

我有 2 个 Eclipse 项目.一个是gwt项目，一个不是.这是对我有用的目录结构:

I have 2 Eclipse Projects. One is gwt project and one is not. Here's the directory structure that works for me:

workspace
-- gwt-project
   -- src/main/java
      -- com.gwt.GwtProjectModule
         -- GwtProjectModule.gwt.xml
-- non-gwt-project
   -- src/main/java
      -- com.nongwt.package.that.contains.source.you.need
         -- nongwt.gwt.xml
      -- com.nongwt.package.that.contains.source.you.need.client

nongwt.gwt.xml 告诉 gwt 查看client"包的内部，如下所示:

nongwt.gwt.xml tells gwt to look inside "client" package, here's what it looks like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 1.7.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro-source/core/src/gwt-module.dtd">
<module rename-to='nongwt'>
    <inherits name='com.google.gwt.user.User' />
    <source path="client" />
</module>

GwtProjectModule.gwt.xml 然后可以从 nongwt 继承源代码.这是 GwtProjectModule.gwt.xml 中的相关行:

GwtProjectModule.gwt.xml can then inherit source code from nongwt. Here's the relevant line from inside GwtProjectModule.gwt.xml:

<inherits name="com.nongwt.package.that.contains.source.you.need.nongwt" />

确保在 Eclipse 中将非 gwt-project 包含在 gwt-project 的类路径中.这是正常的练习；右键单击gwt-project，选择属性，选择Java Build Path"，单击Projects"选项卡，然后选择non-gwt-project"

Make sure you include non-gwt-project inside gwt-project's classpath in eclipse. It's the normal drill; right click on gwt-project, choose properties, choose "Java Build Path", click "Projects" tab, and "non-gwt-project"

或者，除了在gwt-project的classpath中包含non-gwt-project作为项目引用之外，还可以将non-gwt--project的内容进行jar包，确保jar中包含源码，然后包含gwt-project 类路径中的 jar.

Or, instead of including non-gwt-project in gwt-project's classpath as a project reference, you can also jar the contents of non-gwt--project, ensure that you include the source in the jar, and then include the jar in gwt-project's classpath.
