How to change Eclipse's "associated source" for debugging?
提问by kc2001
I have a jar file that supplies some classes in my development environment. When I'm debugging in Eclipse, when I first step into a class supplied by that jar, Eclipse prompts me to give the location of the associated source files. I do so, and everything's fine.
我有一个 jar 文件，它在我的开发环境中提供了一些类。当我在 Eclipse 中调试时，当我第一次进入该 jar 提供的类时，Eclipse 会提示我提供相关源文件的位置。我这样做了，一切都很好。
Some time later, I replace the jar with a newer version. How can I instruct Eclipse to look in a different place for the newer source?
一段时间后，我用更新的版本替换了 jar。如何指示 Eclipse 在不同的地方寻找较新的源代码？

In the Project Explorer (or Navigator), find the JAR (should be listed under "library path"), right-click, properties, there you can delete the association to a source, and/or provide a new association.
在项目资源管理器（或导航器）中，找到 JAR（应列在“库路径”下），右键单击属性，您可以删除与源的关联，和/或提供新的关联。
Note: you must go to the properties for an individual JAR. You cannot get the equivalent dialog if you click on "JRE System Library"
注意：您必须转到单个 JAR 的属性。如果单击“JRE 系统库”，则无法获得等效对话框

In the package explorer, where the jar is in a library (JRE, Maven dependencies, etc...); right click => properties => java source attachement.
在包资源管理器中，jar 位于库中（JRE、Maven 依赖项等...）；右键单击 => 属性 => java 源附件。
Alternately in the project properties => Java build path => Library tab => select the jar => edit.
或者在项目属性 => Java 构建路径 => 库选项卡 => 选择 jar => 编辑。
