Java 常春藤'；s url解析器是否支持传递检索？

由于某些原因，在使用url解析器指定存储库位置时，我似乎无法解析依赖项的依赖项。但是，当使用ibiblio解析器时，我能够检索它们

例如：

<!-- Ivy File -->
<ivy-module version="1.0">
<info organisation="org.apache" module="chained-resolvers"/>
<dependencies>
    <dependency org="commons-lang" name="commons-lang" rev="2.0" conf="default"/>
    <dependency org="checkstyle" name="checkstyle" rev="5.0"/>
</dependencies>
</ivy-module>


<!-- ivysettings file -->
<ivysettings>
<settings defaultResolver="chained"/>
  <resolvers>
    <chain name="chained">

        <artifact pattern="http://my.internal.domain.name/ivy/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]"/>
      </url>
      <url name="ibiblio-mirror" m2compatible="true">
        <artifact pattern="http://mirrors.ibiblio.org/pub/mirrors/maven2/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
      </url>
      <ibiblio name="ibiblio" m2compatible="true"/>
    </chain>
  </resolvers>
</ivysettings>

Checkstyle是一种开发工具，用于帮助程序员编写符合编码标准的Java代码

使用“ibiblio”解析器，我可以解决项目的两个依赖项（commons lang 2.0和checkstyle 5.0）和checkstyle的依赖项。但是，当尝试独占使用“自定义repo”或“ibiblio镜像”解析器时，我能够解析项目的两个显式定义的依赖项，但不能解析checkstyle的依赖项

这可能吗？任何帮助都将不胜感激。

原因是您没有为“ibibio镜像”解析器指定常春藤图案。您的镜像应该看起来像（不要忘记[classifier]标记）：

但您也可以将ibiblio解析器用于镜像：

  <ibiblio name="ibiblio-mirror" root="http://mirrors.ibiblio.org/pub/mirrors/maven2/" m2compatible="true"/>

Maarten，感谢您的回复，但是您的第一个解决方案似乎不起作用，因为只有我在我的ivy.xml中列出的两个依赖项正在被解决。但是，将ibiblio解析器与自定义根一起使用部分有效。我之所以这么说，部分原因是当我在pattern属性中指定一个新的pattern布局时，Ivy似乎忽略了它，并继续使用它的默认模式。有什么想法吗？这是我正在尝试的解决方案：关于您的自定义ibiblio模式的问题，您能用Ivy trunk版本再试一次吗？您可能会遇到此处报告的问题：。

  <ibiblio name="ibiblio-mirror" root="http://mirrors.ibiblio.org/pub/mirrors/maven2/" m2compatible="true"/>
