Interpreting eclipse .classpath file. What does 'kind="con"' and 'exported="true"' mean?
提问by prosseek
This is the eclipse .classpathfile of the eclipse plugin program that I downloaded.
这是.classpath我下载的eclipse插件程序的eclipse文件。
I think that kind="src"and kind="output"is pretty straight forward, as they means the where the source java files and compiled class files are located.
我认为这kind="src"和kind="output"是相当直接的，因为它们意味着在源java文件和编译的类文件的位置。
The kind="lib"seems to indicate the jar files the plugin is referencing, but I have something that I'm not sure about.
在kind="lib"似乎预示着jar文件的插件引用，但我有一些我不知道的。
- What does the
kind="con"mean? - What is it for the
exported="true"? I think in order to use this plugin, all the jar files that the plugin refers to should be exported, but only some of them are exported.
- 这是什么
kind="con"意思？ - 它有
exported="true"什么用？我觉得为了使用这个插件，插件引用的jar文件都应该导出，但是只导出了一部分。

1) In kind="con", the constands for container, which is interpreted by eclipse as a classpath container. As described in that link:
1）在kind="con"，con代表container，eclipse将其解释为classpath container。如该链接中所述：
A classpath container provides a way to indirectly reference a set of classpath entries through a classpath entry of kind CPE_CONTAINER
类路径容器提供了一种通过 CPE_CONTAINER 类型的类路径条目间接引用一组类路径条目的方法
In other words, it enables grouping of other classpath entries in any way and re-use it wherever (including the ability of having different entries for different projects).
换句话说，它允许以任何方式对其他类路径条目进行分组，并在任何地方重新使用它（包括为不同项目设置不同条目的能力）。
2) exported:
Say you have Project Bthat depends on Project C. The dependency is defined as exported=true. Then, another Project Athat depends on Project B, will have also Project Cpresent on A'a classpath.
2) exported：假设您有B一个依赖 Project 的 Project C。依赖项定义为exported=true. 然后，另一个A依赖于 Project 的 ProjectB也将 ProjectC存在于A“类路径”中。
回答by Will
- kind="con" are indicating classpath containers
- exported=true exports the dependency, meaning that any project that has a depedency on your project can see/access the exported dependencies as well.
- kind="con" 表示类路径容器
- export=true 导出依赖项，这意味着任何依赖于您的项目的项目也可以查看/访问导出的依赖项。
