解释eclipse .classpath文件。什么是“kind =”con“和“exports =”true“意思？ [英] Interpreting eclipse .classpath file. What does 'kind="con"' and 'exported="true"' mean?

问题描述

这是我下载的eclipse插件程序的eclipse .classpath 文件。

我认为 kind =src和 kind =output code>是非常简单的，因为它们意味着源java文件和编译的类文件所在的位置。

kind =lib似乎表示插件引用的jar文件，但是我有一些我不知道。

• kind =con是什么意思？


• exports =true是什么？我想为了使用这个插件，插件所引用的所有jar文件都应该被导出，但只有一些引导出来。

解决方案

1）在 kind =con中， con 代表容器，被eclipse解释为一个 classpath容器。如该链接中所述：

类路径容器提供了一种通过类路径条目间接引用一组
类路径条目的方法换句话说，它能够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（包括能力）对于不同的项目有不同的条目）。

2）导出：
说你有Project B 这取决于项目 C 。依赖关系定义为 exported = true 。那么根据Project B 的另一个项目 A 也将有Project C 存在于 A 'classpath。

This is the eclipse .classpath file of the eclipse plugin program that I downloaded.

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.

The kind="lib" seems to indicate the jar files the plugin is referencing, but I have something that I'm not sure about.

• 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.

解决方案

1) In kind="con", the con stands for container, which is interpreted by eclipse as a classpath container. As described in that link:

A classpath container provides a way to indirectly reference a set of classpath entries through a classpath entry of kind CPE_CONTAINER

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).

2) exported: Say you have Project B that depends on Project C. The dependency is defined as exported=true. Then, another Project A that depends on Project B, will have also Project C present on A'a classpath.
