        tokens.collect { trimTag(it) }
    }

    private static trimTag(pluginVersion) {
        println 'in trim tag'
        int i = pluginVersion.indexOf('-')
        if(i > -1) {
            pluginVersion = pluginVersion[0,i]
        }
        println 'return version' + pluginVersion
        pluginVersion
    }
}


Foo.test(['1.0', '2.0'])

Results in
