Creating update site for my xText DSL [message #1749479]

Hello,

I am creating an update site for my xText DSL, but there are dependecy problems related to the "org.eclipse.xtext.ide".

I created a feature for all the plugins of my DSL, and configured "org.eclipse.xtext.runtime", and "org.eclipse.xtext.ide", yet the installation is complaining with the following error:

Cannot complete the install because one or more required items could not be found.
  Software being installed: ReSA Plug-in feature 1.0.0.201612051741 (org.volvo.resa.feature.feature.group 1.0.0.201612051741)

    To: bundle org.volvo.resa.ide 1.0.0

I am also not clear, what else to include on the dependency part of the feature other than "org.eclipse.xtext.runtime", and "org.eclipse.xtext.ide".

Thank you

Cheers,

does your update site contain the xtext stuff? if yes in which version
if it does not: which other update sites did you configure in your eclipse

how does your feature.xml look like?

Hello Christian,

my update site contains one feature that contains my DSL plugins, and a dependencies.
You will find these in the content of the feature below. If you mean the version for the xtext.runtime, it is 2.9.1.v201512180746. I also have one update plugin that just contains one feature with the following content.

<?xml version="1.0" encoding="UTF-8"?>

Either include the Xtext bundles/features instead of only requiring them. This causes that your update site will contain these bundles as well.
Or add the Xtext update site together with your own one to let the update mechanism search in both.
The third possibility would be creating a composite update site pointing to both update sites, but this is an advanced option which is a bit more complicated when it comes to automating it.

Hi Nas,

how do you create the udpatesite? Via a maven/tycho build?
Did you determine a dedicated target platform?

Regarding the inclusion of .ui plug-ins in your feature
your feature should better be dependent on the feature 'org.eclipse.xtext.ui' instead of the runtime feature + the ide plug-in.

regards,
Christian

Hello Christian,

First sorry for the late reply!

I actually tried creating update sites with manual using a separate plugin for the update site, and also with the maven/tycho - both didnt work.
I didnt define target platform.

But finally, i only created an update site that required my DSL plugins. When installing my DSL plugin first I installed xText Redistributable on the target eclipse tool. Then, it worked.
My goals was actually to create my DSL plugin that includes all the runtime dependency, hence no extra manual installation for the dependencies would be required, but I didnt succeed.

Best,
Nas
