A run configuration in Eclipse defines the environment under which your application will be started, e.g. compiler flag, plugin (classpath) dependencies etc. Sometime a run configuration is called referred to as "launch configuration".
If you start your application a default run configuration will be automatically created for you.
To see and edit your run configuration select your plugin.xml -> Run As -> Run Configurations
In the field "location" you specify their the files will be created which are necessary to run your RCP application.
On the Plug-ins Tab select "Validate plug-ins prior to launching". This will check if you have all required plugins in your launch configuration.
Tip
In my opinion this option should be flagged per default. I submitted a patch for this. Please share you opinion in Bug: Validate should be flagged as defaultIf this check reports that some plugins are missing, try clicking the "Add Required-Plug-Ins" button.
Tip
This may solve errors like "One or more bundles are not resolved because the following root constraints are not resolved" or "java.lang.RuntimeException: No application id has been found."On the tab Arguments you should add the parameter -consoleLog. This will send error message of your Eclipse RCP application to your Eclipse development IDE. Otherwise you will not necessary know that your Eclipse RCP application has a problem.
Tip
In my opinion this option should be flagged per default. I submitted a patch for this. Please share you opinion in Bug: -consoleLog should be default
Tip
Under Windows -> Preference -> Plug-in Development -> Target Platform it is possible to maintain -consoleLog in the tab launching Arguments -> Program Arguments. Then the parameter will always be set for your RCP runtime configurations.
