problem with deploying plugin developed by xtext [message #714703]

Dear all,

I am currently working on building an IDE for ATS (www.ats-lang.org). I have difficulty in deploying the plugin I've developed so far.

I use the current Xtext 2.0 with a "Complete Eclipse Indigo Distribution" downloaded from xtext.itemis.com. I created the Xtext project and wrote the code for ATS language. I ran the mwe2 file and then ran the project as "Eclipse Application". I got a new eclipse which has the support for ATS. Everything is fine.

Then I exported the project as "Deployable plug-ins and fragments" and I copied the generated jar file into the dropins folder of the eclipse I used for developing the plugin. I started a new instance of eclipse and choose folder "runtime-EclipseApplication" as the workspace. In the new instance of eclipse I got the error message "Could not open the editor: No editor descriptor for id org.ats_lang.AnairiatsDats". Did I miss anything? Does it have anything to do with the plugin.xml and plugin.xml_gen? I am a newbie to eclipse and xtext. I am not sure what these two files are for. Any advice is highly appreciated.

BTW, the problem occurrs only on my debian system. I did the same thing on Windows XP. There is no problem at all.

I have received lots of help from people here, which made it possible for a beginner like me to build an editor for a serious language like ATS. I need to learn more about Xtext so that I can improve the editor. But I really want to release the first version to the community of ATS to receive some feed back. If the plugin problem I post now is solved, is it enough that I just release the exported jar file and ask users to put it into the "dropin" folder of their eclipse? Do they have to use the same "Complete Eclipse Indigo Distribution" I am using now? Thanks a lot for your help all the time.

Hi,

as a partial answer:
1) The plugin.xml is nothing Xtext specific.
2) Providing your DSL-jars is not enough as they only contain the code specific to your DSL but the Xtext framework is needed as well. Ideally you would provide an update site containing your code and pointing the the itemis Xtext update sitehttp://download.itemis.com/updates/releases/ which is always a good starting point for getting Xtext running an an existing eclipse

I have no hints regarding the dropins issue.

Need training, onsite consulting or any other kind of help for Xtext?
Go visit http://xtext.itemis.com or send a mail to xtext@itemis.de

It's simple - don't use dropins.
The main problem is when there is a problem you don't know what is wrong
(what is missing, in conflict etc.).

Publish your things as a p2 repository and install from that.

Thank you for your answer. The Xtext framework has been taken into consideration. That's why my test is to put the jar file into the "dropins" folder of the eclipse I used to develop the plugin for my DSL. I assume such eclipse should have the xtext framework.

No useful error message is a problem. I shall try "p2 repository" after I learn what it is.

Today, I tried using p2. On Windows XP, everything goes smoothly. On debian, I got some errors. What I did goes as follows.
I created a feature project which includes all the plugins for my dsl developed using Xtext. Then I exported the feature project as a deployable feature into an Archive file. Later, I added the Archive file as a repository and installed the feature. On linux I got the following error message
============================

==========================================
The eclipse (Eclipse Xtext 2.0.0 Distribution (Indigo)) I am using now is downloaded from "http://xtext.itemis.com/". Did anyone meet this kind of problem before?

On debian again, this time I use another eclipse (Eclipse SDK Version: 3.5.2) without pre-installed Xtext. I installed Xtext on it by the site "http://download.eclipse.org/modeling/tmf/updates/releases/", then created project for my dsl, then created feature project and exported it and in the end installed the exported feature into the same eclipse. Basically I did the same thing as before. But this time it works. Maybe the problem is just caused by the eclipse (Eclipse Xtext 2.0.0 Distribution (Indigo)) released by itemis.

Hi, are you able to create the dirs it is complaining about manually. Maybe you have some flags missing respectively the dir is read-only. Regards Christian

===========

Unable to write to repository: file:/home/skomp/Desktop/distros/indigo-final/tmp/eclipse.

===========

My account is not "skomp" at all. I have no idea where "skomp" comes from. And I don't think "skomp" has anything to do with my machine. Is it possible that it actually came from the environment of the developer of itemis?
