Hi,

i am trying to create a Domain-Specific Language for a Web Application by following the below steps :

1) I select new xtext project and keep the defualt project name, Language Name and extension that the xtext pre-fills ( like --> org.xtext.example.mydsl etc)
2) In the advanced section the facets selected are
i) Eclipse Plugin
ii) Web Integration
iii)Generic IDE Suppport
iv) Testing Support

preferred build System--> Gradle
source Layout --> Plain

After the setup i run the mwe2 artifacts wich creates the model ,the generator and the validation folders sucessfully.
Then i run the project "org.xtext.example.mydsl.web" from the main class " org.xtext.example.mydsl.web.ServerLauncher" as a new aplication.

In the browser (localhost:8080) the web application appears.
The problem is that when i type in the editor, the below errors appears in the eclipse console.

Which Xtext version do you use?
If not 2.15 did you try the workaround (s) described in https://github.com/eclipse/xtext/issues/1231
If 2.15 do you have other dependencies that pull non matching versions of core.runtime and equinox.common

Yes this version is very very old. Is there any reason you use it?

You might find matching versions in the github issue above.
(Just make sure that you use a old version for both equinox.common and core.runtime

Now i am totally lost !
Do i have to put some dependencies in the gradle build file to bypass those issues? The solutions provided in the previous link are mostly referred to maven builds. Correct me iif i am wrong.
Is it better to "leave back" my old version of xtext and install the latest one ?
Thanks for your quick answers .

The problem affects all Xtext versions older than 2.15

So the preferred solution is. Use Xtext 2.15
Yes you have to explicitly tell gradle to use specific versions of core.runtime
And equinox.common

One possibility is this.
https://github.com/itemis/xtext-reference-projects/blob/master/greetings-gradle/2.14.0/org.xtext.example.mydsl/build.gradle

But I don't have a old Xtext wizard available that exactly this works for you too
