Hi guys,
I'm trying to install (or add) a new developed plugin-jar to an already existing/deployed RCP-application. I want to find an easy way to extend the already existing RCP-application. So what we're looking for is a way to provide such an "additional" plugin.jar that the user can copy to his installation folder and then start the application and use the functionality that is provided by that plugin.jar. We do not want to bundle that plugin.jar during the initial provisioning of the application (which would of course be trivial). Furthermore we've removed all the "add software" dialogs from our RCP application itself. So what we need is to "inject" the additional plugin "from outside" the running RCP application.
First of all, I'm using 'Eclipse for RCP and RAP Developers' (Version: Neon.3 Release (4.6.3)). The RCP-application was created by using the 'Eclipse product export wizard' of the corresponding product-file. The product configuration is based on a feature-file ('feature.xml') which describes all using plugins. Now I'm looking for an easy way to extend this exported RCP-application with a new developed feature (plugin-jar). I already tried different ways, which unfortunately didn't work. In the following, I will describe these different attempts:
1. I tried to add the corresponding plugin-jar to the plugins-folder of the RCP-application. Afterwards I started the application with the command "rcpapplication.exe -clean". The added plugin wasn't loaded...
2. Additionally (to 1.) I modified the 'feature.xml' file of the rcp-application by adding the plugin-information. Afterwards I started the RCP-application with the command "rcpapplication.exe -clean". The added plugin wasn't loaded...
3. I created the following folders: 'plugins'-folder under 'dropins'. I added the plugin-jar in the new created plugins-folder. Afterwards I started the RCP-application with the command "rcpapplication.exe -clean". The added plugin wasn't loaded...
Moreover, here is a way that was working (but in my opinion, it isn't an easy way):
• I added the plugin-jar to the plugins-folder of the RCP-application. I modified the bundles.info-file (folder: RCP-applicationFolder\configuration\org.eclipse.equinox.simpleconfigurator) by adding a new line with the information of the new added plugin-jar. The new line looks like 'newplugin,1.0.0.201708141356,plugins/newplugin_1.0.0.201708141356.jar,4,false'. Afterwards I started the application with the command "rcpapplication.exe -clean" and it was working...
Now, is there an easier way to add a plugin-jar to an already existing RCP-application?
Best regards,
Murat
