ApacheIvy内置NetBeans解决导入问题

Question

我想使用Apache Ivy在Java中解决我的项目内部的一些依赖项（导入）。我正在使用NetBeans 7.1.2（JavaEE版本）。我已经安装了IvyBeans插件（版本1.2）。然后我构建了我的项目，Ivy已经在我的项目文件夹内创建了IvyFiles和IvyLibrary文件夹（它们都为空）。问题是没有解决任何库。我从构建器获得以下消息：

[PATH_TO_PROJECT]\nbproject\ivy-impl.xml:92: settings file does not exist: [PATH_TO_PROJECT]\${ivy.settings.location}

这是常春藤解析输出：

我对ApacheIvy在NetBeans下的工作方式有什么误解吗？我的设想是，我在我的项目中使用一些依赖项——然后我构建它，Ivy会自动从互联网上获取依赖项，我不必关心将所有外部库添加到我的项目中。

有没有解决这个问题的建议？

非常感谢您的帮助或任何建议：）

看来你的常春藤决心很管用。在构建文件中，如何使用解析的JAR来填充ANT项目的类路径？

一个流行的选项是调用ivy retrieve任务来填充本地lib目录：

   <ivy:retrieve/>
   <path id="build.path">
      <fileset dir="lib" includes="**/*.jar"/>
   </path>

我的偏好和建议是使用ivy的缓存路径任务：

   <ivy:cachepath pathid="build.path"/>

下面给出了一个更完整的示例（使用常春藤配置）：

Ant脚本，用于在多个版本的类路径之间进行选择
