----------------------------------------
Summary: Unify Ambari Versioning Across Modules
Key: AMBARI-24804
URL: https://issues.apache.org/jira/browse/AMBARI-24804
Project: Ambari
Issue Type: Task
Affects Versions: 2.8.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Fix For: 2.8.0
It looks like Ambari’s trunk pom.xml has not been updated with a proper version
in at least 4 years. It currently still lists trunk as 2.0.0.0-SNAPSHOT:
{code}
<groupId>org.apache.ambari</groupId>
<artifactId>ambari</artifactId>
<packaging>pom</packaging>
<name>Ambari Main</name>
<version>2.0.0.0-SNAPSHOT</version>
<description>Ambari</description>
{code}
This poses several problems as we try to make our artifacts more 3rd-party
friendly since it becomes ambiguous what other maven projects are actually
depending on. We need to change our process to keep this version updated with
every release of Ambari. Other Apache projects seem to do this (I took a look
at Nifi, Hive, Storm, etc) and in each case, their trunk pom.xml was at least a
minor version ahead of their most recent release branch.
- We should change the version specified for Ambari and its submodules to use
the next major version after a release, such as {{3.0.0.0-SNAPSHOT}}. Once 3.0
has been released, this will be changed to {{4.0.0.0-SNAPSHOT}} even if there
are more builds in the 3.x line off of {{trunk}}.
- Maven 3.5.0 allows the ability to specify a
{{<version>${revision}</version>}} placeholder value in the parent {{pom.xml}}
which submodules can inherit. This seems cleaner than having all of the
submodules updated and checked in using the {{mvn versions:set
-DnewVersion=3.0.0.0-SNAPSHOT}} command.
- If any submodule inherits from {{ambari}} or {{ambari-project}}, then they
should broadcast their version as the same. This includes submodules such as
{{ambari-utility}} which are hard coded at {{1.0.0.0-SNAPSHOT}} which makes
understanding what actually exists in local repos very difficult.
