Interesting. I'd love to hear what the issue was.

I spent more time working on this and am still having this issue. The Java SmartDashboard is opening with the same arguments I pass to it (java -jar /path/to/dashboard/SmartDashboard.jar) but for some reason, the one spawned through selecting the "Java" SmartDashboard is refusing to acknowledge my plugin. When I open it through the command line, it opens it and loads my extension/plugin.

The Camera widget still does not work for me and won't establish a connection when opened through the command line. It works fine if it is opened through the Driver Station. I used a process monitoring tool to confirm that it is opening the same SmartDashboard I'm opening via command line (shoutout to Procmon!).

I'm nearly at my wits end for this issue and have tried almost everything I can think of. Due to the non-existent documentation for SmartDashboard I've decompiled SmartDashboard and am trying to determine the cause of this issue but it's not going too well.

If anyone who has experience with extensions/widgets or a SmartDashboard developer sees this I would love it if you could post.

Thanks.
