produce the following file
~/.ivy2/cache/net.sf.launch4j/launch4j/ivy-3.0.2.xml
<?xml version="1.0" encoding="UTF-8"?> <ivy-module version="2.0"> <info organisation="net.sf.launch4j" module="launch4j" revision="3.0.2" status="release" publication="20111120230713" default="true" /> <configurations> <conf name="default" visibility="public"/> </configurations> <publications> <artifact name="launch4j" type="zip" ext="zip" conf="default" classifier="win32"/> <artifact name="launch4j" type="tgz" ext="tgz" conf="default" classifier="macosx"/> <artifact name="launch4j" type="tgz" ext="tgz" conf="default" classifier="linux"/> </publications> </ivy-module>
In this file, the classifier attributes do not have a namespace which will cause validation to fail and the build cannot be done offline, because launch4j is redownloaded on every retrieve like seen here:

In DefaultModuleDescriptor.newDefaultInstance() line 112 getExtraAttributes() is used and thus the namespace is lost. Even if getQualifiedExtraAttributes() would be used this would not suffice, as then the namespace declaration is missing and again the validation would fail.
