Java Eclipse - 如何更改类路径？ [英] Java Eclipse - How do I change the classpath?

问题描述

我将Eclipse项目从我的电脑（eclipse驱动器D）复制到笔记本电脑（eclipse是驱动器c），但是当我尝试部署我的项目中的代理程序时，我会收到以下错误：

存档** D **：/ eclipse / plugins / it.fbk.sra.ejade_0.9.0 / lib / libjade4 / commons-codec- 1.3.jar由类路径引用不存在。

我将所有库的地址更改为正确的地址（ C：/eclipse/plugins/it.fbk.sra.ejade_0.9.0/lib/libjade4 / __ etc __ ），通过右键单击项目>构建路径>配置构建路径。但是这不行。我也尝试刷新项目，重新启动eclipse，但仍然没有。

任何建议？

谢谢很多！

解决方案

我有同样的问题，只是发现了解决方案。

转到 project> properties> Java Build Path> Libraries>添加外部JARS 。

之后在特定位置指定JAR文件，您将在以前的窗口构建路径中的JAR和类文件夹中看到它：JAR_fileName - C：\YOURPATH。

不要停在这里，而不要点击左边的+按钮来展开它，如果它说源附件：（NONE），你双击它，并通过选择Workspace将路径添加到JAR文件位置。

这解决了我的问题。

I copied an Eclipse project from my PC (eclipse is on drive D) to the laptop (eclipse is on drive c) but when I try to deploy the agents I have in my project I keep getting the following error:

The archive **D**:/eclipse/plugins/it.fbk.sra.ejade_0.9.0/lib/libjade4/commons-codec-1.3.jar which is referenced by the classpath does not exist.

I changed all the libraries' addresses to the correct ones (C:/eclipse/plugins/it.fbk.sra.ejade_0.9.0/lib/libjade4/__etc__) for all of them by right clicking the project > build path > configure build path... but that doesn't work. I also tried to refresh the project, restart eclipse but still nothing..

Any suggestions?

Thanks a lot!

解决方案

I had the same problem and just discovered the solution to this.

Go to project>properties>Java Build Path>Libraries>Add External JARS.

After specifying JAR file at a certain location, you will see it in previous window "JARs and class folders on the build path:" with "JAR_fileName - C:\YOURPATH".

Don't stop here instead click on the "+" button to the left to expand it, and IF it says "Source attachment: (NONE)", you double click it and add the path to the JAR file by selecting Workspace location.

This solved the problem for me.
