      I have a script I can run via terminal, and via the envinject plugin

      import javax.net.ssl.HostnameVerifier
import javax.net.ssl.HttpsURLConnection
import javax.net.ssl.SSLContext
import javax.net.ssl.TrustManager
import javax.net.ssl.X509TrustManager

def nullTrustManager = [
    checkClientTrusted: { chain, authType ->  },
    checkServerTrusted: { chain, authType ->  },
    getAcceptedIssuers: { null }
]

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

SSLContext sc = SSLContext.getInstance("SSL")
sc.init(null, [nullTrustManager as X509TrustManager] as TrustManager[], null)
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory())
HttpsURLConnection.setDefaultHostnameVerifier(nullHostnameVerifier as HostnameVerifier)

URL url = new URL('<my svn https url>');
URLConnection conn = url.openConnection();
String basicAuth = "Basic " + <my base 64 encoded user:pass> ;
conn.setRequestProperty ("Authorization", basicAuth);

svnPageContents = conn.content.text
regexGroup = (svnPageContents =~ /svn - Revision (\d+):/)
printf ("found: ${regexGroup[1][1]}")

      This just connects to svn to get the latest rev number, on a svn server with a self signed cert. On the console and in envinject this works fine. In the workflow plugin groovy script it exceptions out

      java.lang.NullPointerException: Cannot get property 'text' on null object

      So my openConnection is returning null. I don't know why, but it's easy to reproduce
