Make the JVM trust all SSL certs

trustAllSSL.groovy

void trustAllSSL() {
    def trustAllTrustManager = [
            checkClientTrusted: { chain, authType ->  },
            checkServerTrusted: { chain, authType ->  },
            getAcceptedIssuers: { null }
    ]

    def trustAllHostnameVerifier = [
            verify: { hostname, session -> true }
    ]

    def sc = javax.net.ssl.SSLContext.getInstance("SSL")
    sc.init(null, [trustAllTrustManager as javax.net.ssl.X509TrustManager] as javax.net.ssl.TrustManager[], null)
    javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory())
    javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(
        trustAllHostnameVerifier as javax.net.ssl.HostnameVerifier)
}
