Eclipse RCP application with Eclipse ICE [message #1767875] Tue, 11 July 2017 19:56 Go to next message

The scope of this project is to build a custom workflow using Eclipse ICE. Eclipse ICE is a version of Eclipse with the EAVP plugin installed. This plugin automates your workflow by taking you through some wizards that create a config file for you that essentially allows you to build custom commands that execute other applications that may or may not be heavily dependent on data.

There are four elements to this project.
Eclipse ICE, Eclipse RCP app, EAVP VisIT plugin and a python script.

The goal is to build an RCP app that calls the python script. The python script calls visit which generates some graphics in python widgets. I want to get the python widget and embed a visit plot inside an Eclipse RCP app.

The python widget can obtained in Java in the like manner:

  // Send a Python command to the widget, directing it to set the
// model to the correct timestep.
VisItSwtConnection widget = getConnection().getWidget();
ViewerMethods methods = widget.getViewerMethods();
methods.processCommands( "SetTimeSliderState(" +widgetTimestep.get() + ")");



The problem I'm running into is configuring the RCP app to be able to import org.eclipse.eavp.viz and org.eclipse.eavp.viz.service in order to execute the above code upon some button clicks. There appears to be two ways to do this. Create a target with all dependencies that overrides the manifest or maintain the manifest and add the external plugins to the product feature. I've tried both and am currently failing at adding the plugin and dependencies to the feature.

After EAVP plugins are added to the Included Plug-Ins tab for the products feature, there becomes a host of dependencies that need to be manually resolved almost one at a time.

Is there a better way to discover dependencies other than one at a time?

This error is not remediable:
Unresolved requirement: Import-Package: org.eclipse.equinox.internal.p2.metadata

The package org.eclipse.equinox.internal no longer exists it seems. Do I have to roll back to a previous equinox version? If so how is that done?

Bumping for relevance.

My problem now is installing a plugin manually in eclipse to be used for dependency.

Usually technologies you use will have features that group the various plugins into larger groupings and it's easier to define a product based on such features. E.g., for Oomph's installer product we only have this product dependency:
   <plugins>
   </plugins>

   <features>
      <feature id="org.eclipse.oomph.setup.installer"/>
   </features>
so all the detailed dependencies are specified by that feature:

</feature>
Note that the feature dependencies reduce the list of plugin dependencies dramatically, but somewhere a list (feature) needs to be maintained, hopefully by folks providing the technology but in the worst case, by you.
