Groovy Snippet

List<String> getMavenVersions(String metadataXmlURL) {
    def strVersions = new ArrayList<String>()
    def mvnData = new URL(metadataXmlURL)
    def mvnCN = mvnData.openConnection()
    mvnCN.requestMethod = 'GET'

    if (mvnCN.responseCode==200) {
        def rawResponse = mvnCN.inputStream.text
        def versionMatcher = rawResponse =~ '<version>(.*)</version>'
        while(versionMatcher.find()) {
            for (nVersion in versionMatcher) {
                strVersions.add(nVersion[1]);
            }
        }
    }

    strVersions.sort {v1, v2 ->
        v2.compareTo(v1)
    }

    return strVersions
