Error in Eclipse preferences window, Jnario option is unusable

[trylks]

To whoever may be working or will work on this, I hope this helps in the identification and solution of the problem.

Please let me know if any more information would be useful.

The problem arises when clicking on the Jnario part of the tree in the preferences window, either for projects or in the general Eclipse preferences. Everything else in the preferences window seems to work fine.

Versions:

Eclipse DSL Tools

Version: Luna Service Release 2 (4.4.2)
Build id: 20150219-0600

Error:

Unable to create the selected preference page.

Log

The log is in a gist, was too long to be posted here.

The problem is that Jnario is currently incompatible to xtend 2.8. @borisbrodski is currently porting Jnario to Xbase, which will fix these kind of problems in the future.

Thanks for this great framework.

Have you any idea about a release date for this porting?

[borisbrodski]

Unfortunately I can't estimate the amount of the remaining porting work. It works actually already but there are some bugs present. Also the maven build has to be ported.

By the way, it would be really great, if someone could do the maven porting.

Any update on the above error as i installed the plugin today and still getting the same exception. Do you have workaround? or any time frame when the fix will be available.
Thanks.

Here you will find the newest sources of the ported Jnario.

https://github.com/borisbrodski/Jnario/tree/no_xtend_xtext2.9?files=1

Please, build “no_xtend_xtext2.9“ branch yourself with

mvn clean install

It works with the latest Xtext.
