Java:我如何知道给定类名要使用哪个 jar 文件? [英] Java: How do I know which jar file to use given a class name?

问题描述

给定一个类，org.eclipse.ui.views.navigator.ResourceNavigator 例如，我如何找出要使用的 jar 文件?我知道它在 org.eclipse.ui.ide 中，但我如何才能找到它?

Given a class, org.eclipse.ui.views.navigator.ResourceNavigator for example, how do I find out which jar file to use? I know it's in org.eclipse.ui.ide, but how would I find that out?

编辑:感谢所有回答问题的人.像许多事情一样，似乎有几种方法可以给这只猫剥皮.我希望 javadoc 包含此信息.到目前为止，这里是不同的方法:

Edit: Thank you to all of you who answered. Like many things, there seems to be several ways to skin this cat. I wish javadoc contained this info. So far here are the different methods:

1. 没有 Internet、Eclipse 或 NetBeans:

1. Without Internet, Eclipse or NetBeans:

for f in `find . -name '*.jar'`;  do echo $f && jar tvf $f | grep -i $1; done

如果您想使用 Eclipse 在本地查找:

If you want to find out locally using Eclipse:

• JAR 类查找器插件
• 类定位器插件

如果你想从网上找到或者你还没有jar:

If you want to find out from Internet or you do not have the jar yet:

• jarFinder
• findjar.com

推荐答案

您还有这个 Eclipse 插件:jarclassfinder

You also have this eclipse plugin: jarclassfinder

用户输入未找到的类名(或Java项目需要访问的类名).该插件将在所选目录(和子目录)中搜索包含该类的 JAR 文件.

The user enters the name of the class not found (or the name of the class that the Java project needs to access). The plug-in will search the selected directory (and subdirectories) for JAR files containing that class.

所有结果都显示在自定义视图的表格中.然后，用户可以浏览此表并选择 JAR 文件以添加到他的 Java 项目的构建路径中.然后，用户右键单击表中的条目，并从上下文菜单中选择要将其添加到的构建路径.

All results are displayed in a table in a custom view. The user can then browse this table and select the JAR file to add to his Java project's build path. The user then right-clicks on the entry in the table and, from the context menu, selects the build path to which to add it.

更新 2013，正如我在搜索 .jar 文件 eclipse"中提到的，它不再维护，并且替代品很少.

Update 2013, as I mention in "searching through .jar files eclipse", it is no longer maintained, and the alternatives are sparse.

作为 sunleo 评论 下面:

对于 Eclipse，Ctfl+Shift+T 仍然是寻找类型的最简单替代
(在状态栏中显示 jar 名称).

with Eclipse, Ctfl+Shift+T remains the easiest alternative to look for a type
(with the jar name displayed in the status bar).

user862268 评论 下面:

对于mac，在Eclipse中是cmd+shift+T来查找类和相关的jar.

For mac, it is cmd+shift+T in Eclipse to find the class and associated jar.
