individual start level with feature based launch? [message #540447]

Hello,

I'm playing with the new feature based target definition and feature
based launch introduced in 3.6.

I noticed that the feature based launch configuration has no option to
define an individual start level (for whole features or single bundles).
But I have a project, where I need to start bundles with an order.

Is there a way, how I can use a feature based launch with additional
individual start levels?

Regards,
Lars

Hello,

I have similar issue with feature based launch configurations. I would
like to set auto-start to true for some bundles. I have a p2.inf file
with markStarted(started: true); in the bundles I would like to
auto-start, but this does not help.

Any ideas?

Thanks,
Luzi

PDE does not allow you to customize start levels in feature based launch. The goal was to make it easier to make simple launch configurations. You can file an enhancement request, but the PDE team has no plans to add the functionality to feature based launch.

Similarly, PDE launches do not consider information in a p2.inf file. You may be able to get p2 to recognize the inf file by creating a custom configuration.ini to launch with on the configuration tab.

Thanks for the clarification. I will file an enhancement request. For
me, it seems that you would like to customize start-level and auto-start
in the standard use case (e.g. a bundle with a DS component has to be
started). How does it work for the standard bundles such as
org.eclipse.osgi or simpleconfigurator which need a specific start level?

May you explain this approach a little bit deeper?

Luzi

Ever since certain bundles needed specific start levels, the launch configs have had a bit of 'magic' code that would set the start levels for you. When we enabled setting specific start levels, the code stayed and is used to initialize the settings. The code is also used in the feature launch to set the start levels.

I thought there was a configuration property you can set to specify the location of an advice file (p2.inf). However, I looked around but can't find any such property. This might make difficult to support p2.inf when self hosting as there isn't a way to tell p2 where to look.
