release:prepare optional build step

[dan tran <da...@gmail.com>]

Hello, At my shop, we do daily realease using maven-release-plugin.
Currently maven makesure the source is buildable before perform the label.
Then at the perform step, maven builds again.

Is it reasonable to have maven skips the build at prepare step.
This way we can cut down the build time ( in half) ?

We can introduce a doPrepareBuild  field which defaults to true.

It turns out, the prepare step never do the build ( i missed read it).

Hi there,

I do not think there is any real benefit in the addition of this
field.  The prepare goal in the maven-release plugin is all about
tagging a working instance of the project within the SCM.

The plugin ensures you are in sync with the development trunk of the
project.  Next by executing the build life cycle on the trunk maven is
ensuring that at least you can fully compile and pass the unit tests. 
If someone used this flag and bypassed this stage in the prepare
process a tagged instance of the project could get into a state where
it may not even compile.  Maven at this stage is helping you to make
sure the SCM is in the best possible state, (it can build).

If a release is performed, (extracted based of a tag name) and it
cannot even compile then that release is worthless and a waste of
resources preparing it and storing it in the SCM.  It is all about not
wasting time at later stages.  If you take the hit and ensure the
release can complete the full build life cycle then developers can
spend time later addressing the real issues and not the basics of
whether the release can be built in the first place.

Also the release process could be divided between 2 people, someone to
prepare the release and another to perform it.  By completing the
build life cycle both parties can enough that they are delivering a
working solution to their audiences.

Hope this is cool, just want to explore the issue.
