什么是来源JAR？ [英] What is a sources JAR?

问题描述

我最近试图导入一个库用于我正在处理的事情。

我遇到了一些困难，因为我添加到构建路径的JAR是JTransforms-3.0-sources.jar而不是JTransforms-3.0.jar。

<现在我有点挠头，想知道第一个sources.jar是什么，如果它没有我想要使用的任何类。

它是什么？它是什么？

解决方案

源jar是一个只包含源代码的jar（ .java文件）对应于编译的工件。在IDE中将其添加为源附件，发布源等非常有用。

因为它只包含源，而不是编译类（.class文件） ，它作为库依赖没有用。

I was recently trying to import a library to use for something I am working on.

I was having some difficulty because the JAR that I added to the build path was the "JTransforms-3.0-sources.jar" and not the "JTransforms-3.0.jar".

Now I am sort of scratching my head and just wondering what that first sources.jar was if it didn't have any of the classes that I wanted to use in it.

What is it and what is it for?

解决方案

That sources jar is a jar that contains only the source code (the .java files) corresponding to the compiled artifact. It is useful to add it as a source attachment in your IDE, to publish the sources, etc.

As it only contains sources, not compiled classes (.class files), it is of no use as a library dependency.
