NullPointerException in dbm-gorm-diff after creating new domain classes for Oracle 11g

[trettstadtos]

Hi,

I am encountering an NPE when running dbm-gorm-diff and using Oracle 11g as a database. It seems to work with H2 and also works in Oracle if I just change something in an existing domain class. But the error occurs after creating a new domain class.

This is the output of the grails command:

$ grails dbm-gorm-diff --stacktrace --debug
:compileJava UP-TO-DATE
:compileGroovy UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:findMainClass
:dbmGormDiffCommand execution error: liquibase.command.CommandExecutionException: java.lang.NullPointerException
 FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':dbmGormDiff'.
> Process 'command 'C:\Projekte\sdk\jdk\jdk1.7.0_80\bin\java.exe'' finished with non-zero exit value 1

* Try:
Run with --info or --debug option to get more log output.

* Exception is:

Command [dbm-gorm-diff] error: Could not execute build using Gradle installation 'C:\Projekte\sdk\gradle-2.9'.

To help reproduce the problem I created an example project: https://github.com/trettstadtos/database-migration-gorm-diff-npe. The project is a freshly created Grails app using Grails 3.1.5 and Gradle 2.9. I added the configuration for the grails-database-migration plugin in build.gradle, added a new domain class and modified the datasource in application.yml

You need to run an Oracle Database server locally. The version I use is Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production. I created a new user as follows:

$ sqlplus

@trettstadtos Can you test this with version 2.0.0.BUILD-SNAPSHOT of the plugin?

I've tested this with plugin version 2.0.0 and Grails 3.1.11.
The problem encountered was that for some reason liquibase-core version 3.4.2 was always selected as dependency. (dependencyInsight did not provide any information about the reason)
Once I explicitly added
runtime "org.liquibase:liquibase-core:3.5.3"
I was able to execute dbm-gorm-diff against oracle database
