This is a chicken-and-egg question:

Can I use EASE to create and set up a new workspace?
What am I doing wrong if it's possible?

What I tried is:
1. I saved an EASE script in SVN (which just does a print)
2. I invoked it in an empty folder using a script argument with a URL value, like this (for more info see log below):

-script http://192.168.1.2/svn/company/EASE/trunk/src/newworkspace.py


This just hung.

The eclipse log showed a series of error messages some of which appear routinely and I've been ignoring since they haven't prevented my EASE scripts from running...

here's the error log (only slightly edited):

Hi,

executing scripts from a URL should work just fine. Eg try:
eclipsec -application org.eclipse.ease.runScript -workspace "~/my workspace" -script "https://git.eclipse.org/c/ease/org.eclipse.ease.scripts.git/plain/Demos/EclipseCon%20Europe%202017/demo/01%20Simple%20Scripts/01%20Hello%20World.js"


Which prints "Hello World" to your console.

Things that might go wrong:
* URL encoding (look for special characters and escape them properly)
* website authentication. SVN smells like user/pass might be needed
* certificates in case you use https

Setting up a workspace is a common usecase in my company. Just remenber to supply the location of your fresh workspace on the command line.

HTH
