第一步， 把第三方庫加到workspace :? ?https://stackoverflow.com/questions/370814/how-to-set-a-breakpoint-in-eclipse-in-a-third-party-library

? ?The most sure-fire way to do this (and end up with something that's actually useful) is to download the source (you say that it is open-source), and set up another "Java Project" pointing at that source.

To do that, get the source downloaded and unzipped somewhere on your system. Click "File"->"New"->"Java Project". In the next dialog, give it a project name and select "Create Project from Existing Source". Browse to the root location of the open source library.

Supposing that all the additional libraries that are required by the project and such are included in the project you downloaded, Eclipse will figure everything out and set the build path up for you.

You'll need to remove the open source jar from your project's build path, and add this new project to the build path of your project.

Now, you can just treat this as your code, and debug at will.

第二步 ， include 新添加的項目?

Right Click > Project.

Click Project Properties.

Click Java Build Path.

Click the Projects Tab.

Click the Add Button.

Select the Project.

Click OK.

第三步 ： 這時調試， 如果斷點在 第三方庫 內部， 會發生 "Source not found" 錯誤，?

　　　　所以 ， 需要在? debug configuration ---> Source ---> Source Lookup Path?

　　　　add 第三方工程 。
