Parent Pom get version of Child Pom/dependency - maven-2

Question

I have a project like the following
mainProject - Multi Module Project structure:
pom.xml
newfolder/pom.xml
otherProject:
otherProject.pom.xml with mainProject.pom.xml as its parent pom and newFolder/pom.xml as a dependency.
see below:
mainProject pom.xml:
<groupId>test.test</groupId>
<artifactId>mainProject</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>newFolder</module>
</modules>
<dependency>
<groupId>test.test</groupId>
<artifactId>newFolder</artifactId>
<version>${project.version}</version>
</dependency>
newfolder/pom.xml:
<groupId>test.test</groupId>
<artifactId>newFolder</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<parent>
<groupId>test.test</groupId>
<artifactId>mainProject/artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
otherProject:
<parent>
<groupId>test.test</groupId>
<artifactId>mainProject</artifactId>
<version>1.0-SNAPSHOT/version>
</parent>
<dependency>
<groupId>test.test</groupId>
<artifactId>newFolder</artifactId>
</dependency>
The problem is when I try to build otherProject it cannot find the version of newfolder because it is not pulling in the version of the project that I built it is still looking for newfolder 1.0-SNAPSHOT
Any help would be great!

Answer 1

I was able to get the behavior I was hoping for by adding ${project.parent.version} to the parent pom dependency. example:
<groupId>test.test</groupId>
<artifactId>mainProject</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>newFolder</module>
</modules>
<dependency>
<groupId>test.test</groupId>
<artifactId>newFolder</artifactId>
<version>${project.parent.version}</version>
</dependency>
