Question

i have 3 maven project (starto.commons,starto.hibernate,starto.server) that use some same dependencies and two of then use the thread project(commons).

i try to unit the 3 project to one big maven project (lets call him starto.bigMavenProject for the example)

i mean that:

1) every project stay project on its own bat use the starto.bigMavenProject pom for dependencies

2)when i build (run mvn insatll) starto.bigMavenProject it’s build the all three project (starto.commons,starto.hibernate,starto.server).

thanks in advance.

It sounds like you want a Maven parent project for your three projects. I’d suggest taking a look at the POM documentation on inheritance as well as Sonatype’s simple example.

Basically, you want a POM for start.bigMavenProject something like this:

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                             http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>starto</groupId>
    <artifactId>bigMavenProject</artifactId>
    <packaging>pom</packaging>
    <version>1.0</version>

    <modules>
      <module>commons</module>
      <module>hibernate</module>
      <module>server</module>
    </modules>
</project>

Though you may need to do some additional tweaking to, e.g., your directory structure, etc.

The key thing is your parent POM should have <packaging>pom</packaging> and define each sub-project as a module.
