Versioning problems
I' ve a project so structured.
---aaa.progettoPilota-------------|--------- progettoCommons
| |______ pom.xml
|
|-------- progettoBusiness
| |______ pom.xml
|
|--------- progettoSistema
| |______ pom.xml
|
|--------- progettoWeb
| |______ pom.xml
|
|_________ pom.xml
Top level pom has versioned in this way:
...
<modelVersion>4.0.0</modelVersion>
<groupId>aaa.progettoPilota</groupId>
<artifactId>progettoPilota</artifactId>
<packaging>pom</packaging>
<version>2.0-SNAPSHOT</version>
...
All child projects inherit the version in this way:
...
<parent>
<artifactId>progettoPilota</artifactId>
<groupId>aaa.progettoPilota</groupId>
<version>2.0-SNAPSHOT</version>
</parent>
...
I've a local central snapshot repository. Maven try to download new
snapshots versions each 60 seconds.
The dependencies are:
progettoWeb depend from progettoSistema
progettoSistema depend from progettoBusiness
progettoBusiness depend from progettoCommons
I'm using dependency management, such as
<dependencyManagement>
<dependencies>
<dependency>
<groupId>aaa.progettoPilota</groupId>
<artifactId>commons</artifactId>
<version>${project.version}</version>
</dependency>
<dependency>
<groupId>aaa.progettoPilota</groupId>
<artifactId>business</artifactId>
<version>${project.version}</version>
</dependency>
<dependency>
<groupId>aaa.progettoPilota</groupId>
<artifactId>sistema</artifactId>
<version>${project.version}</version>
</dependency>
<dependency>
<groupId>aaa.progettoPilota.web</groupId>
<artifactId>progettoWeb</artifactId>
<version>${project.version}</version>
</dependency>
...
Now, let go to the problem.
1) Deploy all the projects on the repository (clear at the beginning) using
"mvn deploy" command at the top pom.xml level.
All projects in the repository have the same format, for example:
"business-2.0-20061103.154755-1.jar". In particular
build number is 1 for all.
2) Let go into progettoWeb directory and try to compile with "mvn clean
compile" command. Maven checks for dependency,
eventually update and it's all right.
3) Let go into progettoSistema and deploy only this project (mvn deploy). In
the snapshot repository I'll have: sistema-2.0-20061103.155109-2.jar (buil
number 2)
4) Let go into progettoWeb and compile (mvn clean compile). It's all rights.
5) Now, try to use maven from another machine or clean your "local
repository" (%user_HOME%\m2\repository...).
Go into progettoWeb and try to compile (mvn clean compile).
Maven SHOULD BE downloads all snapshots from local central repository and
compile progettoWeb.
Instead I get an error such as:

*******************************************************************************************************************************
The problem is that maven try to dowload the snapshot "business" with build
number 2, but build number 2 is to "Sistema", not business. Also the
"qualifier"
20061103.155109 is not of "business" but of "sistema" (business is
business-2.0-20061103.154755-1.jar). It looks like that maven make a mix
between name and version of
"business" and "sistema".
Is this a BUG ???
I'm making a mistake in the versions managements of projects ?
Thank you in advance.
Alex.
