Eclipse platform URIs in command line [message #1863300]

Hello all,
I have a Xtex DSL where other DSLs are imported. I saw in one of the projects that a team is using Platform URIs for the imports. This breaks the command line (jar) execution for validation of DSLs as there is no concept of Platform URIs in the command line.

I am not sure how to tackle this issue and where should I look into.
Does it make sense to programmatically convert these URIs to something else during command line? Any help is highly appreciated.

My Import rule looks like below:

Import:
importURI=STRING ;

Thanks for the reply. What is the place I should replace these platform URIs to some relative uris before they go to validation / generation etc? I tried use a custom URI handler but I do not get anything there. However I could change these Import URIS in the scoping part to set them to relative if it is non eclipse context. Do you think that is the right approach?

i dont know what you do in your standalone tool.
but before you load the models.
maybe you can look into the ImportUriResolver / ImportUriGlobalScopeProvider

Thank you for your reply, Christian!
Is it generally considered a good idea to change the importURI value in scoping for command line execution ?
I see that there is a scoping class implemented based on ImportUriGlobalScopeProvider in my project and I can modify the importURIs to relative paths from platform URIs during command line execution.
Do you see any issues with this approach or it should be done somewhere else ?

no, if you fill the uri map properly
it will resolve

platform:/resource/xxxxxx/yyyy/zzzz.mydsl to the correct file

if i wound have an example i would have pointed you.
i also did not get any information on what you do in your command line tool.
i assume you need to decide therere that platform:/resource/xxx/yyyy/zzzz.mydsl is file:///x/y/z/yyyy/zzzz.mydsl

i already pointed you to standalonesetup. check what it does in
setScanClassPath
