如何“安装”一个log4j包？ [英] How do I "install" a log4j bundle?

问题描述

我已经下载了Eclipse插件的代码。代码使用log4j，但它不仅将其用作库（引用jar），而且将其用作bundle。所以没有编译，原因如下：

I've downloaded the code for an Eclipse plugin. The code uses log4j, but it doesn't just use it as a library (referred jar), but as a "bundle". So it doesn't compile because of the following reason:

Bundle'org.apache.log4j'无法解析

Bundle 'org.apache.log4j' cannot be resolved

我不太确定什么是正确的方法来解决这个问题。我知道如何添加罐子到一个项目，但如何添加捆绑？是否需要添加到整个Eclipse主机？

I'm not really sure what's the correct approach to solve this. I know how to add jars to a project, but how do I add "bundles"? Is it something I need to add to the entire Eclipse host?

我通过创建一个没有代码的新的插件项目来解决这个问题，但是包含了log4j jar。但是这并不是正确的解决方案。

I "solved" this by creating a new plugin project with no code but with the log4j jar included... but that doesn't feel like the right solution.

我还发现了一些出现log4j bundle的地方，例如：

I've also found some places where "log4j bundles" are published, e.g.:

• http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.org.apache.log4j&version=1.2 .16


• http ：//download.eclipse.org/tools/orbit/downloads/drops/R20110523182458/

• http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.org.apache.log4j&version=1.2.16
• http://download.eclipse.org/tools/orbit/downloads/drops/R20110523182458/

但我是不确定这是我需要的，如果它是重要的，我得到它，以及如何安装它。

But I'm not sure if that's what I need, if it matters where I get it from, and how to "install" it.

推荐答案

我假设您正在使用Eclipse插件开发环境（PDE）。在这种情况下，log4j包需要导入到目标平台中。

I assume you are using the Eclipse Plugin Development Environment (PDE). In this case, the log4j bundle needs to be imported into the "Target Platform".

目标平台就像一个捆绑（即插件）替代的存储库传统Java开发中的classpath。您可以找到目标平台的位置，并通过转到首选项 - >插件开发 - >目标平台进行修改。

The Target Platform is like a repository of bundles (i.e. plug-ins) that replaces the "classpath" in traditional Java development. You can find the location of the target platform and modify it by going to Preferences -> Plug-in Development -> Target Platform.

HOWEVER 在此之前，我强烈建议您花点时间来了解一下您正在做的工作！如果您想开发Eclipse插件，您应该至少了解一个插件是什么，以及它的依赖关系如何工作。如果您阅读有关该主题的内容，您不必在Stack Overflow上提出这样一个非常基本的问题，请参见所有介绍性教程和常见问题解答。

HOWEVER before doing this I strongly recommend you take some time to learn a bit about what you are working on! If you want to develop an Eclipse Plug-in you should at least learn what a plug-in is, and how its dependencies work. If you read a bit about the subject you should not have to ask such an extremely basic question on Stack Overflow... it is covered in all the introductory tutorials and FAQs.
