NetBeans 中的 Apache Ivy 用于解析导入

Question

我想使用 Apache Ivy 来解决我在 Java 项目中的一些依赖项（导入）。我使用的是 NetBeans 7.1.2（Java EE 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在我的项目文件夹中创建了IvyFiles和IvyLibraries文件夹（它们都是空的）。问题是没有解决任何库。我从构建器获得以下消息：

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

这是常春藤解析输出：

我这边对Apache Ivy在NetBeans下的工作方式有什么误解吗？我的愿景是在我的项目中使用一些依赖项 - 然后我构建它，Ivy会自动从Internet获取依赖项，我不必关心将所有外部库添加到我的项目中。

有什么建议如何解决这个问题？

非常感谢您的帮助或任何建议:)

看起来你的常春藤决心工作正常。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 检索任务来填充本地 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"/>

这里给出了一个更完整的示例（使用 ivy 配置）：
