Created DSL plug-in don't work on a new Eclipse project [message #1742108]

Hello guys.
I created my DSL, I tested it with "Eclipse Application" and it works fine.
So I have exported my projects as a plug-in, selecting "Deployable plug-ins and fragments" as recomended on the forum and at the xtext documentation. But when I have imported then in a other Eclipse for some tests, they were imported. I created at a new project a new file with my DSL extension but nothing happened. In Eclipse > Installation Detais > Plug-ins it is not shown. If I try to install it through the Help > Install New Software and I point to the directory with the generated plug-in files, Eclipse shows "There are no items available".

Note: I don't have any project with sufix ".sdk" as some comment in some issues at the forum, instead I have a project ".feature".

I have been searched a lot at Google, but without success.
I attached some pictures to facilitate.
I'm gratefull for any help.

you have to do the following on export:

(1) in the wizard select feature and update site option (this gives you the feature.xml and a category.xml)
(2) rightclick the feature.xml -> Export -> Deployable Features ->
(3) (Select target, on options select category.xml)
(4) Finish

if you choose maven in the wizard the it will create a repository zip for you

Ps and you should install the plugins and not "import" them

Thank you very much, it is working fine now.
To help others perhaps with the same situation, I will tell the steps that I have done:
I'm using Eclipse Neon Release (4.6.0) DSL Tools and xText version 2.10.0.
1) Choose menu File > Export
2) I selected "Plug-in Development > Deployable features", and clicked "Next"
3) In "Available Features" I checked my DSL feature
4) I typed the directory where I would like to save the plug-in
5) In "Options" page I checked "Package as individual JAR archives"
5.1) I checked Generate p2 repository
5.2) I checked Categorize repository: and I selected my "category.xml" file
6) Finally I clicked on "Finish" button.

On other Eclipse instalation I have installed my DSL plug-in:
7) Choose menu Help > Install New Software
8 ) Clicked on button "Add..."
9) After clicked on button "Local..."
10) Pointed to the directory informed in step 4 above (Location field)
11) Typed "My DSL name" in field "Name" and clicked "OK" button
12) Finally I checked my DSL feature and clicked "Finish" button
If Eclipse ask you to restart it, say yes.
After we can create our DSL file and it will use our DSL Editor installed above.
Perhaps it will be necessary to set the xText nature to the project.

Hi,
I followed your steps to export the plugin of my dsl. But in "Available Features" no features are listed. Do I need to click anything before I choose export? Earlier I followed File-> Export->Plug-in Develoment->Deployable plug-ins and fragments->selected the five projects related to my dsl->destinations directory was given->checked package plugins as individual jar archives->finish.

But when I try to install the plug-in through Help -> Install New Software-> Click on Add button->Click on Local button->Select the plug-in folder->Click Ok. It says couldn't find the file. Actually can you explain separately what to choose from these two methods "Deployable plug-ins and fragments" and "Deployable features"?

Thank you.

did you select to create a feature when creating the xtext project?
if not you need to create it manually.
have a look on what the wizard generates

Hi,
No I didn't choose "create feature" when creating the xtext project. Then I guess I need to create the project again.

Hi,
"5.2) I checked Categorize repository: and I selected my "category.xml" file". In my case I don't have a category.xml file. I have feature.xml and two plugin.xml files.

To create the xtext project what I did was file->new->project->xtext->xtext project->gave names for project and extensions->checked 'create feature' in facets ->finish. I followed this path because "file -> new -> other -> feature project " in this way no xtext projects create.

Haven't I followed a correct path?
Thank you.

Hi,
I had followed the following procedure later.

- created a new feature project
- added the plugins of my dsl to the feature project
- used the export -> deployable features wizard

But again "category.xml" file is missing. How can I find it?
Thank you.

Hi,
I am sorry. I didn't understand "Create it there is a wizard as well (category definition I think) ".

Hi,
Actually I don't have a .sdk project to create the category definition. What needs to be selected to create the category definition? I have the following projects.
1.mydsl project
2.mydsl.feature project
3.mydsl.ide project
4.mydsl.tests project
5.mydsl.ui project
6.mydsl.ui.tests project

I am using Eclipse Neon.

You have explained earlier to use the .sdk project.
Quote:

the xtext wizard creates a project yourdsl.sdk
this project can be used to create a p2 repository (update site) containing your plugins.

therefore

(1) create a new category definition in the sdk project. give it a name and add the org.xtext.example.mydsl.sdk featur
(2) rightclick on the feature.xml
(3) export -> deployable features
(4) choose a location (folder or zip)
(5) under options choose the category.xml file created before
(6) hit finish

if you add this update site + one containing xtext (you may download the all in one repo zip http://www.eclipse.org/modeling/tmf/downloads/?project=xtext), then p2 should do all dependency magic for you.

Hi all,
Another very easy step to export your dsl plug-in is using Maven, e.g. open your prompt command (I'm using Windows) go to your parent xtext project directory and type mvn clean install. The plug-in artifacts are generated into the ...youdsl.repository/target/repository folder. The repository contents are your plug-in that should be installed in another Eclipse.
