Subject Re: maven classifier on ant install task
Date Mon, 03 Feb 2014 10:22:41 GMT
Hi,

thanks for your answer once again.

My ivysettings.xml file now looks like:


<ivysettings>

  <settings defaultResolver="chain" defaultConflictManager="all" /> <!-- get all
revisions without any eviction -->

  <caches defaultCacheDir="${ivy.cache.dir}/no-namespace" />

  <resolvers>

    <filesystem name="fs1">
      <ivy

         pattern="${dest.repo.dir}/no-namespace/[organisation]/[module]/ivys/ivy-[revision](-[classifier]).xml"
/>
      <artifact

         pattern="${dest.repo.dir}/no-namespace/[organisation]/[module]/[type]s/[artifact]-[revision](-[classifier]).[ext]"
/>
    </filesystem>


    <chain name="chain" returnFirst="true" dual="true">

      <ibiblio name="central" m2compatible="true"

         pattern="[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]"/>

    </chain>

  </resolvers>

</ivysettings>


Unfortunately, when I run the ant task the result is:

The other libraries are downloaded as expected.
