[jira] [Comment Edited] (HADOOP-15369) Avoid usage of
${project.version} in parent poms
[ https://issues.apache.org/jira/browse/HADOOP-15369?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16439645#comment-16439645 ]

I agree that we need to document this. [~bharatviswa], the maven-enforcer-plugin message already contains the information about the hadoop.version is required.
[~elek], can you add the additional step to release to the hadoop wiki if this has not been added yet?

> hadoop-project/pom.xml and hadoop-project-dist/pom.xml use _${project.version}_ variable in dependencyManagement and plugin dependencies.
> Unfortunatelly it could not work if we use different version in a child project as ${project.version} variable is resolved *after* the inheritance.
> From [maven doc|https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Inheritance]:

> For example, to access the project.version variable, you would reference it like so:
> <version>${project.version}</version>
> One factor to note is that these variables are processed after inheritance as outlined above. This means that if a parent project uses a variable, then its definition in the child, not the parent, will be the one eventually used.
> {quote}
> The community voted to keep ozone in-tree but use a different release cycle. To achieve this we need different version for selected subproject therefor we can't use ${project.version} any more.
