Re: [tycho-user] Unsatisfied dependency to fragment in feature

Hi Bernhard,

 

I have checked it again and it is not correct. Following is example demonstrating my problem:

 

We have in reactor 1 (source code without build):

plugin.1.0.0-SNAPSHOT

MANIFEST.MF – has version 1.0.0.quialifier

feature.1.0.0-SNAPSHOT

<feature

      id=" feature"

      label=" Feature"

      version="1.0.0.qualifier">

   <plugin

         id="plugin"

         version="0.0.0"

         unpack="false"/>

</feature>

 

When this is build and installed into local maven repository I have there following:

plugin.1.0.0-SNAPSHOT

MANIFEST.MF have version 1.0.0.201308060957

feature.1.0.0-SNAPSHOT

<feature

      id=" feature"

      label=" Feature"

      version="1.0.0.201308060957">

   <plugin

         id="plugin"

         version="1.0.0.201308060957"

         unpack="false"/>

</feature>

 

In .repository\.meta\p2-local-metadata.properties is

customer:plugin:1.0.0-SNAPSHOT

customer:feature:1.0.0-SNAPSHOT

 

So I think that plugin is not correctly installed in maven repository, because version 1.0.0.201308060957 is not installed in maven repository.

 

Now if I try in another reactor build product which contains the feature I get following error:

[INFO] Cannot complete the request.  Generating details.

Have you checked:

 

.m2/repository/.meta/p2-local-metadata.properties

 

Which is tychos locally build artifacts index ..

 

When bundles are build before, they are listed there and they can be fetched by your build from there via id reference in a feature/product..

Be sure to have the correct syntax for reference…

Do you delete local-repo before building the first reactor and reference the plugin in the feature via magic number 0.0.0 ?

Tycho will also install in the local repository the plugin jar with the qualifier (in a "hidden" separate location) and should be able to resolve it.

Hi,

 

We are building large eclipse project using maven and tycho.

 

I have split the whole project into several reactors.

 

Problem what I have is that when last reactor is build, it has internal dependency to result of previous reactors.

 

When I checked maven repository I see that plugins are available but they have not correct version. The feature is installed in maven repository with version containing –SNAPSHOT, also created jar has SNAPSHOT in name, but when I check context of feature.xml I see qualifier replaced with a build date and all plugins have also replaced qualifier in versions. So then this feature can’t find the plugin because in maven repository is accessible with SNAPSHOT and not with exact version.

 

Can you please let me know what can be wrong here.


Thanks,

Jan
