Class Not Found errors when upgrading grails to 2.5.0 for Grails database migrations files

I am trying to upgrade Grails app from 2.4.3 to 2.5.0 version. Grails 2.5.0 contains fixes and improvements but doesn't have any breaking changes. Also, installed all 2.5.0 compatible plugin versions.

Also gone through Grails Database Migration Plugin changelog and other plugin to support grails 2.5.0. Come across same JIRA Issue I am facing right now - Jira Link , but it's already fixed in old Grails database migration plugin release.

BuildConfig.groovy

grails.servlet.version = "3.0" // Change depending on target container compliance (2.5 or 3.0)
grails.reload.enabled = true
grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.project.target.level = 1.6
grails.project.source.level = 1.6

grails.project.dependency.resolver = "maven"
grails.project.dependency.resolution = {
    inherits("global") {
    }
    log "warn"
    checksums true // Whether to verify checksums on resolve

    repositories {
        inherits true // Whether to inherit repository definitions from plugins
        grailsPlugins()
        grailsHome()
        mavenLocal()
        grailsCentral()
        mavenCentral()
        mavenRepo "http://repo.grails.org/grails/core" // Dependency for export plugin.
    }
    dependencies {
        compile ("org.apache.jclouds.provider:cloudfiles-us:1.6.2-incubating", "org.jclouds:jclouds-compute:1.6.0") {
            excludes "jclouds-core"
        }
        compile 'commons-beanutils:commons-beanutils:1.8.3'
        compile "org.apache.jclouds:jclouds-core:1.7.2"
        runtime 'mysql:mysql-connector-java:5.1.29'
    }

    plugins {
        runtime ':database-migration:1.4.0'
        runtime ":hibernate:3.6.10.18"
        runtime ":jquery:1.11.0.2"
        runtime ":resources:1.2.14"
        compile ":scaffolding:2.1.2"
        compile ':cache:1.1.8'
        build ":tomcat:7.0.55.2"
    }
}

StackTrace I have migration file named upgrade-2.1.groovy at default migrations location grails-app/migrations

This isn't related to the plugin or Grails - the problem is that upgrade-2.1 isn't a valid name for a Groovy script. You can only use names that would be valid class names. You'll have to replace the period with another character and also possibly the dash. Try upgrade_2_1.groovy.
