Multiple artifacts of the module X are retrieved to the same file in Apache Ivy?

Question

I am getting below error when i build with ant :

BUILD FAILED
/Users/rajeevprasanna/Desktop/Nutch/nutch-release-1.14/build.xml:116: The following error occurred while executing this line:

I have configuration set as per this post :

<target name="resolve-default" depends="clean-default-lib" description="--> resolve and retrieve dependencies with ivy">
    <ivy:resolve file="${ivy.file}" conf="default" log="download-only"/>
    <ivy:retrieve pattern="${build.lib.dir}/[artifact]-[type]-[revision].[ext]" symlink="false" log="quiet"/>
    <antcall target="copy-libs"/>
  </target>

  <target name="resolve-test" depends="clean-test-lib, init" description="--> resolve and retrieve dependencies with ivy">
    <ivy:resolve file="${ivy.file}" conf="test" log="download-only"/>
    <ivy:retrieve pattern="${test.build.lib.dir}/[artifact]-[type]-[revision].[ext]" symlink="false" log="quiet"/>
    <antcall target="copy-libs"/>
  </target>

commons-codec dependency is like below in ivy.xml :

<dependency org="commons-codec" name="commons-codec" rev="1.10" conf="*->default" />

Can someone tell me what i am doing wrong?

Do you need all the confs mapped to your `default` ? – cantSleepNow Feb 23 '18 at 20:17 — cantSleepNow, Feb 23 '18 at 20:17
Rajeev, could you solve the issue? I am stuck on the same. – user87407 Jun 12 '18 at 09:01 — user87407, Jun 12 '18 at 09:01

Add the configuration name (conf) to the retrieve pattern, so that dependencies belongingn to multiple configurations (default and test, ...) map to different directories:

<ivy:retrieve pattern="${build.lib.dir}/[conf]/[artifact]-[type]-[revision].[ext]" symlink="false" log="quiet"/>

Multiple artifacts of the module X are retrieved to the same file in Apache Ivy?
