xtext 2.25.0 + jdk 11.0.11 [message #1842316] Wed, 16 June 2021 08:42 Go to next message
Eclipse UserFriend
Hi,

i have created a simple hello world project in xtext with web instegration.
The xtext i am using is the latest one (2.25.0).
Version: 2021-03 (4.19.0)
Build id: 20210312-0638
I also installed the prerequired jdk 11.0.11 in my system.
I generate the artifacts for the provided "Hello" dsl sucessfuly.
The problem is that when i run the jetty in eclipse, i get the following error :

does C:\test.web\bin\default exist? or is it just C:\test.web\bin\

can you debug this and check the path you see there? maybe it needs some windows \ vs \\ treatment.
can you also check where this path is coming from?

Actually the path C:\test.web\bin\default doesn't exist .
The path that exist is this one C:\Users\PowerLab\Desktop\eclipse11\workspace\Test\test.parent\test.web\bin
The workspace i have created is inside the eclipse folder.
Is this the reason why? I will try to create a project outside the eclipse folder and be back for the outcome.

do you have buildship installed? how did you import the gradle projects? are there any errors when you do a rightclick-> gradle-> refresh gradle projects in console?
how does your .classpath look like?

Hi Cristian,

No i don't use a build Ship .
I don't know how, but the error doesn't appear again after reinstalling the eclipse project. Maybe something went wrong during the previous installation.
If the error arises again (hope not), i 'l inform you.

Thanks Cristian !!!

Hi

It appears that Jetty is causing a lot of trouble at present and forced a respin of Eclipse 2021-06 to accommodate 10.0.5. Your usage of 9.4.36 looks dangerously old wrt 2021-03.
