Hello colleagues,

I have a tools that based on xtext 2.8.4. This tools is used in production as standlone DSL IDE. For building standalone application I've created eclipse product file and save it in separate project. Now I would like to migrate to 2.9.x level of XText and use maven as build system. What there correct way for migratting from 2.8.x that use eclipse build system to 2.9.x with maven?

Thank you in advance
Alexander

do you want to keep the old generator infrastructure or move to the new generator
- if you want to keep simply go with a normal tycho build
- if you want to use the new one: create a new Project and copy & paste your files

Thanks Ditrich

I would like to use new one. What about my product project should I save it and used it in new version of project.?

And one more question When I created new project I see a few options
like

1. Eclipse Plugin
2.Generic IDE support

In case I use my tools only as standalone DSL IDE. I schall not check options one. Am I right?

Thanks
Alexander

the question is

- do you want to target
(a) eclipse
(b) idea
(c) web
(d) no ide at all

so what is a "standalone dsl ide"?

I would like to have eclipse based application. That can be run by my end user as ordinary Windows Application. On xtext 2.8,x I've create product defintion and built it using "Eclippse product export wizard" option. Then I have distribution that can be copied to end user's machine and executed

hi,

then id chosse

- build system maven, layout plain.
- add a feature and repository project the the parent manually and configure tycho to build the feature and the product.
e.g. in https://github.com/cdietrich/xtext-maven-example (which is still 2.8.4 - but there is no difference in the feature/product part)

Using workaround from my other questions from my previous question. I did maven build and have to jar files.

-- org.xtext.example.mydsl.ide-1.0.0-SNAPSHOT.jar
-- org.xtext.example.mydsl-1.0.0-SNAPSHOT.jar

UPD: strongly recomended use : set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m
otherwise outofmemory in maven - exceptions can be caught
Both archive don't contain attribute MainClass in manifest.
I cannot understand How can I run the application?

I use native maven support from xtext, not tycho.
In previous answer you suggest to use tycho. Does it mean that native maven support in text cannot build dsl ide? Like I did it in 2.8.4

no.

if you want to have eclipse plugins you need:
layout plain and choose facet eclipse plugin in the wizard

if you want to run a java main you have to pimp the invocation of the assembly plugin in the pom

so summary of this discussion. Righ now I'm able to build via maven simple example "Hello World" project.
but I do not understand how to create executable jar file for this application.

For example
-- Which class should be main class
-- How to added dependecy from eclipse

I've found https://github.com/xtext/maven-xtext-example. download and try to build. Build complete with success. But I have the same questions How can i make executable jar for this application?
Which jar is main and how can I run this example application

Thanks
Alexander

according to Lorenzo Bettinis book page 94, you have to modify your mwe2 file to get a Main class:

// generator API
fragment = generator.GeneratorFragment auto-inject {
generateJavaMain = true
}

I am having an issue too in migrating from xtext 2.8.1 to 2.9.1 in eclipse Indigo. It has a lot of download errors in the MWE2 plugins.
Is there a clear steps to resolve dependencies for the plugins in the upgrading? I have been trying a lot of stuff related to eclipse but it was in vain Sad

The workflow should be fine. What are the errors you get. Are you sure the
mwe2s deps are ok?

Here is what I did:
I made sure that I have "Contact all update sites during install to find required software" and choose "Xtext Complete SDK Version 2.9.1" ... do I have to select any thing else for the EMF and the MWE2?

guess using an up to date mwe2 would be fine as well.
but it should work with the old workflows with the old version.
thus my question: what is the error you get?
