常春藤的url解析器支持傳遞檢索嗎？

Question

出於某種原因，我似乎無法解決使用url解析器指定存儲庫位置時依賴關係的依賴關係。但是，使用ibiblio解析器時，我可以檢索它們。

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"> 
     <url name="custom-repo"> 
     <ivy pattern="http://my.internal.domain.name/ivy/[organisation]/[module]/[revision]/ivy-[revision].xml"/> 
     <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 ivy.xml file generated from pom via ivy:install task --> 
    <?xml version="1.0" encoding="UTF-8"?> 
<ivy-module version="1.0" xmlns:m="http://ant.apache.org/ivy/maven">

     <conf name="system" visibility="public" description="this scope is similar to provided except that you have to provide the JAR which contains it explicitly. The artifact is always available and is not looked up in a repository."/>

     <dependency org="com.google.collections" name="google-collections" rev="0.9" force="true" conf="compile->compile(*),master(*);runtime->runtime(*)"/> 
    </dependencies> 
</ivy-module> 

使用「ibiblio上」解析器我沒有問題，我解決項目的兩個依賴（公共琅2.0和5.0的CheckStyle）和CheckStyle的的依賴。但是，當試圖完全使用「custom-repo」或「ibiblio-mirror」解析器時，我能夠解析我的項目的兩個明確定義的依賴關係，但不能解決checkstyle的依賴關係。

這可能嗎？任何幫助將不勝感激。

原因是你沒有爲你的'ibibio-mirror'解析器指定常春藤模式。你的鏡子應該像財產以後（不要忘了[分類]標記）：

<url name="ibiblio-mirror" m2compatible="true"> 
    <ivy pattern="http://mirrors.ibiblio.org/pub/mirrors/maven2/[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]" /> 
    <artifact pattern="http://mirrors.ibiblio.org/pub/mirrors/maven2/[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]" /> 
    </url> 

但你也可以使用ibiblio上解析爲您的鏡子：

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