Apache IVY : Chain tag | 易学教程

问题

I am new to the apache IVY. I was not able to download the springframework.web.servlet from the default repository(MAVEN) as this jar file is not present in maven repository so for adding a new repository which have this file i have used the Chain tag. But the problem is its downloading all the jar files from maven repo and the springframework.web.servlet from other repository but after that its again try to download all the other jar files from the second repository.

ivysettings.xml

<ivysettings>
   <settings defaultCache="${ivy.settings.dir}/ivy-cache" defaultResolver="libraries"/>
   <resolvers>
      <filesystem name="projects">
         <artifact pattern="${repository.dir}/[artifact]-[revision].[ext]" />
         <ivy pattern="${repository.dir}/[module]-[revision].xml" />
      </filesystem>
      <chain name="chained">
         <ibiblio name="libraries" m2compatible="true" usepoms="false" />
         <ibiblio name="lib" m2compatible="true" root="https://oss.sonatype.org/content/repositories/springsource-releases"/> 
      </chain>

回答1:

I think your issue is that your default resolver is still set to be libraries instead of chained.....

Am I correct in assuming you want to use Maven Central for all dependencies, except those exceptions listed in your modules section? If that is so, then you don't need a chained resolver. The following settings file is much simpler:

<ivysettings>
   <settings defaultCache="${ivy.settings.dir}/ivy-cache" defaultResolver="central"/>
   <resolvers>
      <ibiblio name="central" m2compatible="true"/>

      <filesystem name="local-projects">
         <artifact pattern="${repository.dir}/[artifact]-[revision].[ext]" />
         <ivy pattern="${repository.dir}/[module]-[revision].xml" />
      </filesystem>

      <ibiblio name="spring-releases" m2compatible="true" root="https://oss.sonatype.org/content/repositories/springsource-releases"/> 
   </resolvers>
   <modules>
      <module organisation="com.virtusa" name="dependee" resolver="local-projects"/>
      <module organisation="org.springframework" name="org.springframework.web.servlet" resolver="spring-releases"/>
   </modules> 
</ivysettings>

Note:

I've dropped the "usePoms=false" attribute to the Maven central resolver. You're losing one to the main benefits of using a Maven repo. Pulling down dependencies automatically instead of having to reverse engineer other people's builds :-)
