我按照here的指示行事。我没有找到我能找到的源代码。
的ivy.xml：
<ivy-module version="2.0">

<dependencies defaultconfmapping="*->default,sources">
<dependency org="org.apache.hadoop" name="hadoop-core" rev="1.0.3"/>
</dependencies>
</ivy-module>
输出：

This blog post说要检查配置是否有来源。这个配置似乎表明来源是可能的，虽然我很难说：

该版本的Hadoop在Maven Central中没有源工件：
无法下载不存在的内容： - ）
为了将来自己看到这个，我建议在常春藤和生成和常春藤依赖管理报告中使用configuraitons。
与此示例相关联的报告显示作为“sources”配置的一部分下载的零工件。
<project name="demo" default="retrieve" xmlns:ivy="antlib:org.apache.ivy.ant">
<target name="resolve">
<ivy:resolve/>
<ivy:report todir="build/ivy"/>
</target>
<target name="retrieve" depends="resolve">
<ivy:retrieve pattern="build/lib/[conf]/[artifact].[ext]"/>
</target>
</project>
注意：
<ivy-module version="2.0">
<info organisation="com.myspotontheweb" module="demo"/>
<configurations>
<conf name="compile" description="Required to compile application"/>
