Description

See https://netbeans.org/bugzilla/show_bug.cgi?id=190033 for background. If you run the command listed there with a clean repository under Maven 3.0 beta 3, you get an error, but maven-archetype-plugin does not really help you track it down. Turns out there is a ZipException due to a *.jar file actually being an HTTP error message, but the closest you get is

...
[DEBUG] Found archetype org.codehaus.mojo.archetypes:webapp-javaee6:1.1 in cache: ~/.m2/repository/org/codehaus/mojo/archetypes/webapp-javaee6/1.1/webapp-javaee6-1.1.jar
[ERROR] Failed to close zipFile
...

    at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:107)
    at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145)

With the attached patch, you get more information:
