Grails Maven Plugin

This is now available by including the "set-version" goal in your execution's goal list.

Shouldn't it be included in the grails-app and grails-plugin lifecycles?

Good idea. I'll do it.

Thanks for the contribution

Hmm. I added a new optional mojo "SetVersion" which you could use if you wanted to. However, what we are discussing now is to make the plugin by default overwrite the grails version with the maven version. I am fine with this, but in implementing it we have some decisions.

Currently at 'validate' phase, the plugin invokes MvnValidatePluginMojo which checks to see whether the grails version and maven version match. It borks if they dont. To get around this, I was executing my optional SetVersion before this.

But now that I look at having setVersion be executed every time, it doesnt make sense to me to have v'alidate' check and enforce versions at validate time. It could either ignore versions, or programatically update the grails project at this time itself, or it could invoke 'setversion' to do the job at this time too.

I'm all ears but I propose:

1. MvnValidateMojo doesnt bother checking versions any more.
2. SetVersion is added to default lifeycle to executed at 'process-sources' time to set grails version based on maven version

I don't see the point in checking whether the versions match and think that automatically syncing the two versions is the best approach. If adding SetVersion to the process-sources phase is OK with you, then go for it. Will it work for clean too?

Opening until the automatic syncing of versions is done.

Great news! [GRAILS-5859 maven release:prepare fails because of version not changed in application.properties|GRAILS-5859] might be a duplicate.

Also, set-version doesn't play nicely with the <nonInteractive> config param e.g.

app.version=--non-interactive\n1.16.0-SNAPSHOT
