java - ivy或ivyDE能否在Eclipse中自动将相关jar添加到JAVA构建路径库中？

Question

例如，当我将一个开发良好的开源项目(如 lucene)打开到 Eclipse(同时具有 ant build.xml 和 ivy ivysetting.xml)时，我可以使用 build.xml 运行 ant 以成功构建整个项目。

但是，该项目在一堆乱七八糟的 .java 类中充满了错误。这是由于取消链接到外部 jar 引起的。这些 jar 已经被 ivy 下载并存储在 {user}/.ivy2/cache/中。此外，当我手动将这些 jar 中的每一个放入该项目的构建路径时，错误都消失了。

ivy或者ivyDE之类的工具可以自动把jar包放到JAVA构建路径下吗？

这是 ivy-setting.xml:

如果你使用 Ivy Eclipse plugin .如果安装了它，则需要将 IVY 运行时添加到项目的构建路径中。这可以通过 Libraries 选项卡下的 Project Properties->Java Build Path 来完成，选择 Add Library 然后选择 IvyDE Managed Dependencies。

完成后，Ivy 解析会将 ivy.xml 中指定的所有 jar 添加到项目的构建路径中。
