IVY: Cannot resolve restlet dependency - ivy

Question

I have a java project setup and wanted to use ivy as dependency management tool. However, I could not get the simplest one to work.
Here is the code I have:
ivy.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
<info
organisation="de.fau.fsahoy"
module="de.fau.fsahoy.android.api15"
status="integration">
</info>
<dependencies>
<dependency org="org.restlet.android" name="org.restlet" rev="2.1-RC5"/>
</dependencies>
</ivy-module>
ivysettings.xml
<?xml version="1.0"?>
<ivysettings >
<settings defaultResolver="maven" />
<resolvers>
<chain name="maven" returnFirst="true">
<ibiblio name="restlet" m2compatible="true" root="http://maven.restlet.org/" />
</chain>
</resolvers>
</ivysettings>
The errors I get are:
Impossible to resolve dependencies of de.fau.fsahoy#de.fau.fsahoy.android.api15;working#JonasErl-PC

You can have a look at the repository structure at maven.restlet.org
These errormessages are not the very best unfortunately. How can I fix this?

Answer 1

I could not reproduce your error....
What version of ivy are you using?
How are you invoking the ivy tasks?
Test
build.xml
<project name="demo" default="init" xmlns:ivy="antlib:org.apache.ivy.ant">
<target name="init">
<ivy:resolve/>
</target>
<target name="clean">
<ivy:cleancache/>
</target>
</project>
Build output
