Netbeans “在哪里？”；“外部”；JAR'；s

带JAR的lib文件夹在哪里？从另一个目录加载JAR有什么魔力吗

具体来说，beansbinding-1.2.1.jar在哪里，另一个jar是swing-layout-1.0.4.jar？

但是我不明白这个罐子以前在哪里，不幸的是，我的问题一定不清楚。我的意思是，库文件夹中已经有两个JAR，但我在目录结构中找不到它们。我会更新我的问题。它们都已经在那里显示了，对吗？它们不会显示在树中，因为我觉得它们被放置在项目之外，而您刚刚将它们添加到了外部Yok，谢谢。你能解释一下“外部添加”是什么意思吗？我可以添加一个jar，过一会儿就会展示出来，但是，我想，我的问题是，如果它们是从外部添加的，这意味着什么，它们在哪里？外部意思是不存在于您的项目中，并且您希望在您的项目中使用它们，所以您可以使用add jar/Folder添加它们，这意味着，它们不会实际存在于您的文件夹中，但其作用就像它们位于相同的foldervia build.xml和local.properties中一样
