Subject Re: Maven repo problems? cocoon-validation-impl not found
Date Mon, 07 Mar 2011 10:11:02 GMT
Moi Andre,

Yes, it's counter intuitive! I think the underlying cause is that i've tried
to build our 2.2 Cocoon app minimally, without doing a full local Cocoon
build .. and the Validation blocks we need aren't in 2.2.

Here is the current state of the problem, from Cocoon-users thread
http://www.mail-archive.com/users@cocoon.apache.org/msg46032.html:

I built Cocoon 2.1.11 in ~/.m2/repository as you suggested, and checked that
my settings.xml points to this repo. Now i'm having (what must be total
noob) trouble getting Maven to find the Validation blocks in the local
repo.

I've tried dozens of variations of the following POM dependencies:

<dependency>
    <groupId>cocoon</groupId>
    <artifactId>cocoon-validation</artifactId>
    <version>2.1.11</version>
</dependency>
 <dependency>
            <groupId>org.apache.cocoon</groupId>
            <artifactId>cocoon-validation-impl</artifactId>
            <version>1.0.0-SNAPSHOT</version>
  </dependency>


.. but still get a build fail:

Could not resolve dependencies for project com.mycompany:lsdb:jar:1.0.0:
Could not find artifact
org.apache.cocoon:cocoon-validation-impl:jar:1.0.0-SNAPSHOT


The worst part is with your earlier help, it was working for a few days.
Then the builds started failing again. So if nothing in Maven central has
changed, that means my earlier attempts to install the Validation block
locally (in the Cocoon app, not in the Maven repo) worked.

Now i'm looking for a way to tell Maven to get the -impl block from:

 ~/.m2/repository/cocoon-2.1.11/src/blocks/validation/

.. I've tried a number of things but can't find the key. Any clues?

Cheers,
- Myles
Helsinki
