Starting eclipse and generating an xtext project
with the grammer:
grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl " ...://www.xtext.org/example/mydsl/MyDsl"

Model:
greetings+=Greeting*;

Greeting:
'Hello' name=ID '!';

gives 6 warnings:
Description Resource Path Location Type
Build path specifies execution environment J2SE-1.5. There are no JREs installed in the workspace that are strictly compatible with this environment. org.xtext.example.mydsl Build path JRE System Library Problem

Description Resource Path Location Type
The file "plugin.xml" does not exist in the workspace build.properties /org.xtext.example.mydsl.ui line 5 Plug-in Problem

The newest versions of
eclipse, Xtext and Java are installed.

What's the reason ? incompatible Java?

Thanks

Hi,

there is a difference between "does not work" and these warnings.

so did you run the workflow of the dsl? did you get any errors there. what are the problems you are facing?

the
Quote:

The file "plugin.xml" does not exist in the workspace build.properties /org.xtext.example.mydsl.ui

error message indicates that you didn't run the workflow.

Trying to export it to eclipse there is no new plugin in the directory
therefore I can't find it by retarting eclipse (project new other ...).

Hi,

are you sure there is nothing exported? Xtexct Plugins are just normal plugins so with the export there is nothing Xtext specific.
Btw there is no new project wizard by default for the dsl so no wonder you cannot find it.

To test your dsl you can simply run a new eclipse application from your host eclipse.

Update: And if you export the plugins you should usually place them into the dropins folder of your eclipse.

Hi,
perhaps all works well and I don't find it.
I tried the example described in
...://www.openarchitectureware.org/pub/documentation/4.3/html/contents/xtext_tutorial.html
after exporting (3 Files) as described
I restarted eclipse and tried
Select File > New... > Other... > mydsl Project to create a new mydsl project.
but I could not chosse a mydsl Project.
Is this OK?

Hi,

you are using ther docs oAW 4.3.1 Xtext? - you did not mention this before. oAW 4.3.1 Xtext is a bit outdated. You find the docs TMF Xtext 1.0.x here:
http://www.eclipse.org/Xtext/documentation/1_0_1/xtext.html

Hi,
it works. The reason of the problem was that I did not expect
that the only thing to use the grammer was to create a project
and add a file xyz.mydsl. i. e. the conjunction was the name of
the file ... .mydsl.

Thanks
