[platform-update-dev] Feature pre-requisites - approach, required?, to plugin or feature??
|
I've been studying the last few 051x builds of the Eclipse platform and
have noticed that:
-
All features have a plugin with the same id
-
Some, but not all, features include the <requires> tag.
The JDT feature says:
<requires>
<import plugin="org.eclipse.platform" version="2.0.0"
match="compatible" />
</requires>
The PDE feature does not include a <requires> tag - but it probably
requires platform and jdt.
The platform feature does not include a <requires> tag (and does
not seem to need one).
-
If I use the PDE to create a feature it has a page seems to allow for feature
prereq references from the feature being defined.
I can't get this to work - as features in the workspace are not available
when the add button is pressed.
Question:
Given that we expect the update manager logic to validate the prereqs
for a feature we need to understand the approach that is supported. Should
we be including the <requires> tag in features associated to products
built on the Eclipse platform?
If yes:
-
for all plugins
-
for the plugin with the same id as the feature
-
for other features (when allowed, when syntax understood)
Thanks
