Re: NullPointerException on save config with svn+ssh connection

exact same stack trace with latest lts 1642.3 and 0.0.9. It occured after initial configuration of the scm-sync-config plugin. repo is svn, access is https.

I can reproduce the stack trace by modifying the path to the svn repo for the scm-sync-config plugin. The plugin appears to be defunct with this exception, I can't get it to work with this.

this is reproducible with a vanilla jenkins install, out of the box.

steps to repro:

  1. install latest jenkins using docker: 
    docker run -p 8080:8080 -p 50000:50000 jenkins:latest
  2. navigate your browser to the web interface
  3. Manage Jenkins => Manage Plugins => Updates => Select All => Download now and install after restart
  4. Manage Jenkins => Manage Plugins => Available => Scroll down to SCM Sync Plugin, check the plugin => Download now and install after restart
  5. Manage Jenkin => Configure System => in the SCM sync configuration section

This crashes all the time with the stack trace in the above post shown in the jenkins web-interface.

Note 1: There is no attempt to ask for the credentials.
Note 2: The jenkins console show a different stacktrace, indicating that the crash is caused by a NPE in ScmSyncSubversionSCM.extractScmCredentials (line 60, see screenshots here for the stack trace and a screenshot of the configuration screen.
