It still requires the user to manually modify the datasources though, because Liquibase is kind of sensitive to different databases. E.g. diff’ing an HSQLDB database against a MySQL database will not go well.

I like the above approach, injecting the configuration during runtime, but it still leaves the question of how to get the database driver right…

Ideas?

However, like the original DbDiff.groovy script this does not seem to work with external configurations — i.e. the expected DataSource.groovy does not contain the environment settings (instead they are in an external file located at grails.config.locations — or in this case it does not exist at all).

line:

def testConfig = testConfigSlurper.parse(classLoader.loadClass(“DataSource”))

changed to lines:

def testConfig
try {
testConfig = testConfigSlurper.parse(classLoader.loadClass(“DataSource”))
}
catch (e) {}

if ( testConfig != null ) {
config.grails.config.locations.each({ testConfig.merge(testConfigSlurper.parse(new File(it.split(“:”)[1]).toURL())) })
} else {
testConfig = config.grails.config.locations.inject(new ConfigObject()) { aNewConfig, item -> aNewConfig.merge(testConfigSlurper.parse(new File(item.split(“:”)[1]).toURL())) }
}

Seems to work.
