No component named xxx.yyy.zzz:eclipse.feature is known [message #500284]

Hi,

I´m getting the error I used as the title of my thread if I try to export a p2 site using the buckminster action.

I thought, that exporting p2 sites should be quite easy using buckminster.

I have an existing project.
This project has a main feature which is named de.wagner.product

It includes 5 different product files, because i need to have products which connect to different databases.

The de.wagner.product includes the org.eclipse.rcp feature and all the other plugins I need for my application.

According to some tutorials on the web I just have to add a new feature, lets say I add a feature called de.wagner.product.site

This feature includes the de.wagner.product feature.

Now I should be able to export the p2 site by right clicking my new de.wagner.product.site feature "Buckminster -> invoke action". Then I choose p2.site and add a target.properties which has the standard entries.

When I try to create the p2.site The log says:

No component named de.wagner.product:eclipse.feature is known to Buckminster

I also noticed, that when I click on "buckminster -> invoke actions" the list of available actions is much smaller than on some other projects I have.

For example the actions :
-source.feature.jars
-site.repacked
-feature.jars
...
are missing.

Does anybody know what could cause the error?

It sounds like the meta-data is only partially extracted. Does the feature have all the required fields filled in (id,
version in particular)? Is the feature id different from the actual project name?

Hi,

yes my feature does have an ID which is de.wagner.product. It also has a Version, a Name, a Provider and a Branding Plug-in.

The file names of the five different products are different .

They include different features, but all have the same Version, ID, and Name (in the product configuration editor)

If I temporary move all products except one to a tmp folder outside the project, the site.p2 buckminster action works. So I think this has something to do with more than one product.

Is it not possible to create a p2.site when having more than one product, or are the names versions and ids the problems in this case?

Right-click on the project and choose "Buckminster" -> "View Cspec". That will tell show you what meta-data Buckminster
was able to extract.

Hi Thomas,

I compared the metadata of my de.wagner.product.site feature. The matadata is exactly the same if I have one product in my de.wagner.product feature or five products.

So I checked the metadata of the de.wagner.product feature. When I have five products in my feature I cant even access the buckminster metadata. When I have only one product in my feature I can access the metadata.

So I think the five produts in the feature mess up the metadata.

Do I have to create a feature for each product or is there a way to keep my architecture with five products in one feature or do I have to redesign everything?

Multiple products in one feature should work. Can you please create a bugzilla and attach a sample feature that
reproduces the problem?

Thanks,

Hi Thomas,

I have inspected this problem more detailed and found out 2 major things that lead to this error. I think this is not a bug, maybe my products are not defined well enought.

First of all, more usefull information about my producs.

The 5 products are:
WAGNER.product (Main Product)
WAGNER.dai.dev.product (Product with dai.dev config)
WAGNER.dai.prod.product (Product with dai.prod config)
WAGNER.twt.dev.product (Product with twt.dev config)
WAGNER.twt.prod.product (Product with twt.prod config)

All of them have
ID= WAGNER
NAME = WAGNER

1. Rroblem: The IDs of the products matches

Attribute WAGNER is defined more then once in component de.wagner.product

This error should be fixable by changing each products ID to a unique one.

2. Problem: Same Dependencies

As I mentioned before, each product includes a dependency to a feature de.wagner.configuration.<productname>

But the main feature (WAGNER.product) and the WAGNER.twt.dev.product feature connect to the same database and because of this they include a dependency to the same feature "de.wagner.configuration.twt.dev"

Dependency de.wagner.configuration.twt.dev is defined more than once in component de.wagner.product

So 1. could be fixed easily but I don´t know how to fix 2. without adding a separate feature or deleting one of the two products.

So is this a bug or just some specific issue with my project?

Yes, that's an absolute must.

This sounds like a bug. The fact that several products have the same dependency shouldn't be problem.
