Grails 3 database-migration-plugin initialization error - grails

Question

I recently added database-migration-plugin to my grails 3.0.11 app. The problem is when I try to run-app I get a following error:
ERROR grails.boot.GrailsApp - Application startup failed
Exception in thread "main" org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'springLiquibase_dataSource':
Invocation of init method failed; nested exception is liquibase.exception.ChangeLogParseException:
java.lang.IllegalArgumentException: Script text to compile cannot be null!
Looks like it can't find changelog.xml in my grails-app/migrations folder. My build.gradle file contains:
buildscript {
dependencies {
classpath "org.grails.plugins:database-migration:2.0.0.RC1"
}
}
and
sourceSets {
main {
resources {
srcDir 'grails-app/migrations'
}
}
}
I also added the following lines in my application.groovy file:
grails.plugin.databasemigration.updateOnStart = true
grails.plugin.databasemigration.updateOnStartFileNames = ['changelog.xml']
I would by very gratefull for any advice how to make database-migration-plugin work properly.
Edit:
I created changelog.xml file using $grails dbm-create-changelog command
I also added to build.gradle (as suggested by $grails plugin-info database-migration command):
dependencies {
compile "org.grails.plugins:database-migration:2.0.0.RC1"
}
then I changed it to (following official documentation):
dependencies {
runtime "org.grails.plugins:database-migration:2.0.0.RC1"
}
and then (as suggested by manual for startup error) I forced liquibase:
dependencies {
compile 'org.liquibase:liquibase-core:3.3.2'
runtime 'org.grails.plugins:database-migration:2.0.0.RC1'
}
and
dependencies {
compile 'org.liquibase:liquibase-core:3.3.2'
compile 'org.grails.plugins:database-migration:2.0.0.RC1'
}
The problem still remains: java.lang.IllegalArgumentException: Script text to compile cannot be null!

Answer 1

We ran into the same problem when upgrading to Grails 3.
A look into the code of the grails-database-migration plugin made clear that the configuration parameter is changed from a list updateOnStartFileNames to a single value updateOnStartFileName.
So when you change your config from
grails.plugin.databasemigration.updateOnStartFileNames = ['changelog.xml']
to
grails.plugin.databasemigration.updateOnStartFileName = 'changelog.xml'
it should work again.

Answer 2

I ran into a similar error. In my case we had some lookup tables where we were populating using a hand crafted script which was included into the main changelog.groovy like:
include file: 'data/001-tablex-data.groovy'
except the file name was incorrect - it should have been 002-... instead. The error is basically the same, but there is no reporting to indicate which included file is not being found/parsed, which is a pain. So if you have manually included files, then look for incorrectly named ones in addition to checking the top-level changelog.groovy or changelog.xml

Answer 3

Ok, I finally found a solution. Maybe it will help someone someday. So what I did was simply delete changelog.groovy (i switched from XML to Groovy) file. Then I generated a new one with $grails dbm-create-changelog changelog.groovycommand. As a final step I run $grails dbm-changelog-sync and everything started to work just fine.

I was facing this issue too and in my case, the problem was the order of that block in build.gradoe
sourceSets {
main {
resources {
srcDir 'grails-app/migrations'
}
}
}
It MUST be before the bootRun, like the below code.
sourceSets {
main {
resources {
srcDir 'grails-app/migrations'
}
}
}
bootRun {
jvmArgs(
'-Dspring.output.ansi.enabled=always',
'-noverify',
'-XX:TieredStopAtLevel=1',
'-Xmx1024m')
sourceResources sourceSets.main
String springProfilesActive = 'spring.profiles.active'
systemProperty springProfilesActive, System.getProperty(springProfilesActive)
}
If you put sourceSets after bootRun your application will not find the migrations file.

Make sure:
You have set up the changelog, i.e., the file grails-app/migrations/changelog.xml exists and is valid.
How you do this depends on your situation. The plugin's documentation has a section for how to create the file initially.
Your datasource is set up to use the database that changelog.xml applies to.

Answer 6

Another potential cause for this problem that we had run into was incorrect capitalization. If changelog.groovy references path/someFile.groovy but the actual name is path/somefile.groovy then you will get this error. Make sure the path name capitalization matches.
