P2 and source feature [message #29457]

Hello,

A source features which has been generated via generate.feature has the
same label as the containing feature. With the old update-site mechanism
this did not come to my attention since the old (3.3.) update manager does
not show the source feature. It is automatically installed with its
containing feature but it does not show up in the list of installable
features.

Now, with Eclipse 3.4, when I generate the p2 repository with the PDE
build and then update via this repository, the update manager also shows
included features which includes the source feature. This is quite
confusing because the source feature can not be discriminated from its
containing feature. Both have the same label and version.

How could this situation be handled? Is there a way to modify the label of
the source feature? Or could the p2 generation be modified so that the
update manager does not display included features? So far I have used the
following properties: generate.p2.metadata, p2.metadata.repo,
p2.artifact.repo, p2.metadata.repo.name,p2.artifact.repo.name, p2.flavor,
p2.publish.artifacts

Thanks
Markus

Markus,
You need to get the source feature generated with a different label.
The way to do this is for your normal feature to have its label
externalized: <feature id="foo" label="%label" >
The feature must include a "feature.properties" file that would have
"label=My Feature Label".

Then, you can contribute a different feature.properties (label=My
Source) to the generated source feature. Do this by having a directory
"sourceTemplateFeature" in the normal feature, the contents of this
directory will be copied into the generated source feature.

org.foo.feature/sourceTemplateFeature/feature.properties
/feature.xml
/feature.properties

Andrew, thanks for the detailed answer. It is exactly what I needed. There
was not much left for me to do wrong, but I found it: Make sure that
org.foo.feature/feature.properties is part of bin.includes in
build.properties
