Problem exporting Eclipse product [message #1067047]

I want to export a standalone product with my DSL editor. I followed the tutorial from http://kthoms.wordpress.com/2010/11/12/setting-up-a-rcp-product-for-a-dsl/, but I'm having problems to get it to work.

When I click "Launch an Eclipse application", I get the following error:

!SESSION Fri Jul 05 12:08:13 BRT 2013 ------------------------------------------
!ENTRY org.eclipse.equinox.launcher 4 0 2013-07-05 12:08:13.553

Maybe there is a plugin missing in my DSL feature? If so, I have no idea of which.

When I go to the Run Configurations menu, choose my product configuration, click "Add Required Plug-ins" and then run, it works. So, I must have got most of the configuration right, but can't export the product.

Looks like you are missing org.eclipse.osgi plugin

Ok, so I added org.eclipse.osgi to the list of plug-ins in my DSL feature. Now I got another error message. It's pretty big... it starts with

!ENTRY org.eclipse.core.runtime 4 0 2013-07-05 14:50:35.003

Then, there are a lot of "missing bundles" like this:

!ENTRY org.eclipse.osgi 4 0 2013-07-05 14:50:35.008
!MESSAGE Bundle initial@reference:file:plugins/org.eclipse.core.runtime_3.7.0.v20110110.jar/ was not resolved.

(...)

And at the very end:

!ENTRY org.eclipse.osgi 4 0 2013-07-05 14:50:35.087
!MESSAGE Application error

I tried to add org.eclipse.equinox.common to my feature (not sure if that was what I needed), but I got a even bigger error message.

Hi,

i am not quite sure what you are doing.
you should make use of the validate button in the top right of the product files dependencies tab

Thank you for the quick answer. I just checked the validation, and it showed a lot of "Missing Constraint: Import-Package" and "Missing Constraint: Require-Bundle".

For example, under my DSL plugin, there is:

Missing Constraint: Import-Package: org.eclipse.core.filesystem; version="0.0.0"
Missing Constraint: Require-Bundle: org.eclipse.core.resources; bundle-version="0.0.0"

What do these messages actually mean?

This means that your product
contains features that declare that they need the plugins
org.eclipse.core.filesystem and org.eclipse.core.resources
but you have no feature included that provide these plugins.

btw this is not an xtext specific task so some general reading on eclipse rich client platform might help.

I set the product configuration to be based on plug-ins instead of features, and it seemed easier to find the dependencies.

Now, I have a problem which apparently is specific to Xtext. When I try to open any file in the exported Eclipse product, I get this message in the editor:

Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

And the stack trace:

Toggle Spoiler

This only happens with the exported Eclipse. When I click "Launch an Eclipse application", everything works fine.

Hi,

i bet the build.properties in one of your plugins contains warnings.

They didn't, but the error was there! My UI project didn't have the xtend-gen folder set as a source folder. I also changed the runtime environment from Java 1.5 to 1.7 after finding some errors in the log concerning the usage of the @Override annotation. Now it works. Thank you!
