Hello,
I'm having issues when running ivy retrieve upon directly executing the JAR
instead of using the ivy:retrieve task in Ant.
The reason I am doing this is because I am using NAnt and the exec task instead
of Ant and Ivy tasks.
For instance, the build.xml Ant script of the hello-ivy example implements the following
"resolve" target:
<target name="resolve" description="--> retrieve dependencies with ivy">
<ivy:retrieve/>
</target>
This works perfectly.
Or possibly fails silently...
Porting this to a NAnt script would result in the following "resolve" target:
<property name="ivy.jar" value="tools\ivy\ivy.jar"/>
<target name="resolve" description="--> retrieve dependencies with ivy">
<exec program="java" commandline="-jar ${ivy.jar} -retrieve ivy.xml"/>
</target>
Executing this task throws the following exception:

The error message suggests to "update the retrieve pattern to fix this error."
So I have also tried the following:
<exec program="java" commandline="-jar ${ivy.jar} -retrieve
${lib.dir}/[artifact].[ext]"/>
But the same exception is thrown.
Any ideas?
I think it's a real error, since commons-cli (in common with many maven
generated libraries) probably has multiple artifacts with the same name
(lib, sources and javadoc). Try something like
<exec program="java" commandline="-jar ${ivy.jar} -retrieve
${lib.dir}/[artifact]-[type].[ext]"/>
or, better, update your ivy.xml file so you only depend on the default
conf of maven artifacts, and not *.
