ApacheIvy：使用模式解决依赖关系

Question

我想下载使用ivy的工件：解决，但使用使用[conf]属性的模式。所以我在IvyS中定义了以下内容ettings.xml

<caches defaultCacheDir="${env.IvyLib}\cache" artifactPattern="[conf]\[artifact].[ext]" checkUpToDate="false" />

注意这个模式

artifactPattern="[conf]\[artifact].[ext]"

<configurations>
    <conf name="ConfGroup1" description="First group of dependencies"/>
    <conf name="ConfGroup2" description="Second group of dependencies"/>
</configurations>
<dependencies>
    <dependency org="derby-db" name="derby-db" rev="10.2.2.0" conf="ConfGroup1->default">
        <artifact name="derby-db" type="zip" ext="zip" />
    </dependency>
    <dependency org="derby-db" name="derby-db" rev="10.4.1.3" conf="ConfGroup2->default">
        <artifact name="derby-db" type="zip" ext="zip" />
    </dependency>
</dependencies>

现在可以很好地解决依赖关系，但只为配置创建了一个文件夹：默认。没有为ConfGroup1创建文件夹

另外，我知道这可以通过使用ivy:retrieve实现，但我不想使用它，因为它将涉及将工件从ivy缓存复制到ivy:resolve之后的另一个地方，我有价值数十亿字节的工件。单独复制它们将在构建过程中产生额外的开销，由于项目需求，我无法承担。

常春藤检索任务有一个符号链接选项，可以用来节省空间。
