In Grails is it possible to configure database migrations plug in to run before other plugins?

Question

I'm using the database migration plugin in my app but im having issues when using other plugins that have DB schema dependencies.

I want to use the migrations plugin to setup / refactor my DB in preparation for using a freshly installed plugin (e.g. taxonomy plugin). The problem is that the migrations plugin loads after other plugins so my application is failing before I can even run the migration (schema dependencies not applied). It would seem reasonable to me that DB migrations should run before other plugins (in 99% of cases). Correct?

Is there a way (without customising the migration plugin with "def loadBefore") to force the migrations plugin to load first?

Thanks

Unfortunaltely a plugin's dependsOn and loadAfter properties are set by the plugin developer.

However, you could create a new environment, and use the following config property grails.plugin.excludes to exclude a number of plugins.

Basically I would define a grails environment used for database migration. I would define a datasource for this environment, and in Config.groovy:

environments {
  prodMig {
    grails.plugin.excludes = 'interferingPlugin1,interferingPlugin2'
  }
}

this would exclude plugins interfering-plugin1 and interfering-plugin2 from your prodMig environment.

Then you can run your databse migration command like this:

grails -Dgrails.env=prodMig dbm-update

Interesting idea, ill have to try it out. Thanks – tinny Apr 14 '12 at 10:30 — tinny, Apr 14 '12 at 10:30
