Re: [tycho-user] build products with optionally included features

hi,

in second try I tried to filter out only the optional feature but not the optional plugin. The build doesnât fail but the optional feature (even though it was filtered!) was bundled into the product :(

Iâve created a ticket:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=437683

Hi Neil,

thank you for your response.Â

I proposed a similar question a month or two back. The optional feature does not work like you would hope. I think that is meant more for plugins.

:(

I ended up making two different products because my use case changed, but you can filter out your feature from the target platform when building the product. You can do this by profile and achieve what you need.

Iâve tried the filtering approach as it is described here:Â

http://wiki.eclipse.org/Tycho/Target_Platform#Filtering

But then Iâm getting the exception stated below. Maybe thatâs because Iâm building the artifacts and filtering them out in the same reactor.Â

Hi,

Iâm building an eclipse product and based on the selected maven profile, a certain eclipse feature should be included into the product or not.

I have two feature.xml, lets call them master-feature.xml and optional-feature.xml

master-feature.xml includes optional-feature.xml viaÂ

<includes
    Âid=âoptional.feature"
    Âversion="0.0.0"
    Âoptional="true"/>

The master-feature.xml is always included in the product.

If I build the product with with optional-feature.xml included, all goes well.

If I try to build build the product with optional-feature.xml excluded, I get the error message below:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.20.0:package-feature (default-package-feature) on project master.feature: Execution default-package-feature of goal org.eclipse.tycho:tycho-packaging-plugin:0.20.0:package-feature failed: Could not resolve feature optional.feature_0.0.0; Path to dependency: -> [Help 1]

The optional-feature is indeed not there because Iâm using a maven profile to not include its pom.xml build it when itâs not required.Â

However, since the feature-inclusion happens via optional=âtrueâ, Iâd expect tycho not to complain about it. Is this a bug? Is there another way to build different variants of the same product?

 Moritz
