原因は、hasMany で持ってる子のデータの順序を担保するために、Listで保持していたがその時の名前が被っていたため。


class Book {
	
}

class Author {
    List books = []
    static hasMany =[books: Book]
}


class BookStore  {
    List books = []
    static hasMany =[books: Book]	
}

class Book {

}

class Author {

List books = []

static hasMany =[books: Book]

}

class BookStore {

List books = []

static hasMany =[books: Book]

}

このようにすると、 Book テーブルに、 books_idx というカラムを複数作ろうしてエラーになる。


class Book {
	
}

class Author {
    List books = []
    static hasMany =[books: Book]
}


class BookStore  {
    List bookList = []
    static hasMany =[bookList: Book]	
}

class Book {

}

class Author {

List books = []

static hasMany =[books: Book]

}

class BookStore {

List bookList = []

static hasMany =[bookList: Book]

}

このように、名前を変更すれば、
Book テーブルには、 books_idx と、 books_list_idx となるのでエラーを避けられる。

環境

grails : 3.3.5
database-migration : 3.1.0.RC1

現象

起動時に以下のエラー


liquibase.exception.ChangeLogParseException: java.lang.IllegalArgumentException: Script text to compile cannot be null!

解決方法

build.gradle に以下の文言を入れ忘れていただけ


sourceSets {
    main {
        resources {
            srcDir 'grails-app/migrations'
        }
    }
}

sourceSets {

main {

resources {

srcDir 'grails-app/migrations'

}

ちゃんと説明されていたね。
