Consistent column order in DDL for joinTable

Column order for a joinTable in the DDL generated by grails schema-export is not consistent.

This is a pain as I need to diff the DDL of different versions of my project to find changes but the diff output includes lines where there wasn't a real change (only the order of the columns in the output). The source file didn't change.

As I understand it the columns in the DDL are intended to be: id, version, then the remaining columns alphabetically.

The problem specifically occured with a mapping like this:

class Person {

...

static hasMany = [
managedDepartments : Department
...
]

static mapping =

}

diff target/ddl.sql previous_ddl.sql
...
< create table t_dept_managers (dept_id number(19,0) not null, person_id number(19,0) not null, primary key (dept_id, person_id));
—
> create table t_dept_managers (person_id number(19,0) not null, dept_id number(19,0) not null, primary key (dept_id, person_id));
