Automatic Update of Build Plugin Versions?

[Daniel Johnson <da...@cisco.com>]

Hi,

Is there a simple solution for updating your dependent build plugin versions? I know of versions:display-plugin-updates, but is there anyway to automatically update them as well? I would love to run a goal on an aggregator POM that would update all projects build plugins to the most recent version (or specify a subset of groupId/artifactId plugins to update). Or is this usually just handled by a property in the aggregator POM?

Thanks in advance,
Daniel Johnson

Definitely, the shared parent is your friend if you want manage plugin
versions in one central place. The shared parent is often called
corporate pom.  Define all plugins in the pluginManagement section in
the corporate pom. You can also specify plugin versions as properties,
then you can easily overwrite version in the specific project:

<properties>
<acme-corporate-pom.cleanVersion>2.4.1</acme-corporate-pom.cleanVersion>
</properties>

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-clean-plugin</artifactId>
<version>${acme-corporate-pom.cleanVersion}</version>
</plugin>

The same concept can be used to customize plugins configuration (can
be easily overwritten):

<properties>
<!-- Automatically assign submodules the parent version (m-release-p) -->
<autoVersionSubmodules>true</autoVersionSubmodules>
</properties>

Or use pluginManagement in a shared parent...

Thanks for the response. What you mention is exactly my use case, When I decide I want the new version of a plugin I want to update all projects at once instead of having to open each pom and change it by hand. From your response I am guessing it is expected to use properties to control this.
Thanks,
Dan

Most people want their builds to be "stable" first and foremost, so
this is not a well-supported use case.

Not that I am aware of. But I don't bump plugin versions unless I
suddenly need some new functionality or a specific bug-fix.
