只是对将jar导入Eclipse(插件开发)项目的注释:

In case you are developing Eclipse plug-ins, it makes sense to use Eclipse's native bundling mechanism instead of just importing the jar into a plug-in project. Eclipse (or better its underlying OSGi runtime, Equinox) uses so-called bundles which contain some more information than plain jars (e.g., version infos, dependencies to other bundles, exported packages; see the MANIFEST.MF file). Because of this information, OSGi bundles can be dynamically loaded/unloaded and there is automatic dependency resolution available in an OSGi/Eclipse runtime. Hence, using OSGi bundles instead of plain jars (contained inside another OSGi bundle) has some advantages.

(顺便说一句:Eclipse插件与OSGi包是一回事。)

很有可能有人已经将某个(第三方)库绑定为OSGi包。你可能想看看下面的bundle仓库:

http://www.springsource.com/repository/app/ http://download.eclipse.org/tools/orbit/downloads/ http://www.osgi.org/Repository/HomePage

系统路径下的Jar文件为:

C: \ oraclexe app \ oracle产品10。2。0 \ server \ jdbc lib \ ojdbc14。jar

Ojdbc14.jar (jar文件)

要在Eclipse IDE中导入jar文件，请遵循以下步骤。

右键单击项目 选择生成路径 单击Configure Build Path 单击Libraries，选择Modulepath，然后选择Add External jar 从所需的文件夹中选择jar文件 单击“应用”和“确定”

您可以通过右键单击Project→Build Path→Configure Build Path在Eclipse中添加一个jar。在Libraries选项卡下，单击Add Jars或Add External Jars并给出Jar。这里有一个简单的演示。

上述解决方案显然是一个“快速”的解决方案。然而，如果您正在处理一个需要向源代码控制存储库提交文件的项目，我建议将Jar文件添加到源代码控制存储库中的专用库文件夹中，并引用上面提到的少数或全部Jar文件。

如果你有一个麻烦的udemy课程乍得对进口的罐子。然后按照这些步骤进行。

右键单击项目。 你会看到一个Build Path选项，点击它。 你会有一个选项配置构建路径，点击它。 去图书馆。 然后去你有一个jar文件的地方，把它们放到一个新的文件夹里，上传到一个新的地方。 然后点击Add External Jars，你肯定可以上传它，这也会对classpathxmlapplicationcontext有帮助。

谢谢你！

两个选择:

1/来自项目:

2/如果你已经导入了其他jar，从“References Libraries”目录:
