custom precondition class not found exception

[Madruga]

My precondition is in src/groovy/liquibase/precondition/
MyCustomPrecondition.groovy

possible fix in file GroovyPrecondition, line 70: (working in my
development mode)

replace:
def custom = Class.forName(m.className).newInstance()
with:
def custom = ApplicationHolder.application.classLoader.loadClass
(m.className).newInstance()

don't forget to import ApplicationHolder

Robert, should I raise a JIRA or it's not needed?

[Robert Fischer]

No need: I'll patch this, release it, and move forward.

Now that my custom precondition is being executed, I'm getting errors
with it.

What I understood for custom precondition is that must implement the
CustomPrecondition interface, and if the precondition fails, then the
method throws an CustomPreconditionFailedException, the migration is
marked as failed, in my case, I have onFail: "MARK_RAN" so nothing
should be done, and migration goes on, please adviser if I'm missing
something, because this way I'm getting this:

liquibase.exception.MigrationFailedException: Migration failed for
change set app-autobase::UpdateJsecUserUniqueId::Gcmadruga:

This is a Liquibase issue. There's been a bit of work in the CustomPrecondition space in the most
recent release -- when I push out the next Autobase, give it a shot and let me know if that works.

[Gustavo Madruga]

Thanks for the info.

Any plans on releasing the new version soon?

I might take a shot at with latest dev version (but I think that neither git nor grails svn are up to date?!)

I have to put in a lot of work for my billable client, the book, and GroovyMag right now. Tuesday
morning USA Eastern Time is the next time I've got for doing free work.
