Exactly, therefore you should not use ${project.version} at all, because
during release the value is simply wrong. However, in this case release
plugin cannot adjust the value, because it is "hiding".
Working approach is:
Parent POM:
===========
...
<groupId>group</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
...
<dependencyManagement>
<dependencies>
<dependency>
<groupId>group</groupId>
<artifactId>childA</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>group</groupId>
<artifactId>childB</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
</dependencyManagement>
ChildA POM:
===========
<parent>
<groupId>group</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>childA</artifactId>
...
ChildB POM:
===========
<parent>
<groupId>group</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>childB</artifactId>
...
<dependencies>
<dependency>
<groupId>group</groupId>
<artifactId>childA</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
All those version strings will automatically adjusted.
