多个项目与Eclipse [英] Multiple Projects with Eclipse
问题描述
我的工作区的Eclipse其中有2个项目在这里面。
I have workspace inside of Eclipse which has 2 projects in it.
我想从项目#1引用项目#2,但是当我去项目 - >属性 - >参考,并勾选我想添加为参考项目,我仍然不能够实例化类从项目#2#项目1内。
I want to reference project #2 from project #1, but when I go to Project -> Properties -> References, and tick the project that I want to add as a reference, I am still not able to instantiate the classes from project #2 inside of project #1.
这是一个黑莓应用程序,Java和Eclipse中开发的。
This is a blackberry app, developed in Java and in Eclipse.
PROJECT1
Launcher.java
Project1 Launcher.java
Project2的
Screen.java
Project2 Screen.java
我想用屏幕SCR =新画面(); //位于PROJECT1
推荐答案
您需要将项目添加到构建路径,以便Eclipse Java编译器可以看到其他的项目。
You need to add the project to the build path so that the Eclipse Java compiler can see the other project.
- 选择项目 - >属性 - > Java构建Path->项目标签
- 选择添加...
- 添加项目1,确定返回到工作区。
还有一件事来检查。如果你的类在默认包,他们将不会导入。如果是这样,请尝试移动类明确的包。
One other thing to check. If your classes are in the default package they won't be imported. If they are, try moving your classes to an explicit package.
例如:
import mypackage.Screen;
...
Screen scr = new Screen();
