我使用Grails 2.3.5，GGTS 3.5.0和数据库迁移插件1.3.8。
我在Config.groovy中设置updateOnStart = true。
grails.plugin.databasemigration.updateOnStart = true
grails.plugin.databasemigration.updateOnStartFileNames = ['changelog.groovy']
当我的应用程序第一次运行时（使用空数据库），它会完美启动。 但是当我停止并启动应用程序时，我得到以下错误：
*在更改日志应用后运行dbm-update或dbm-status时会出现类似的错误。（在创建表之后）

更新：
我反编译并在Liquabse.jar（AbstractDatabase.class）中找到错误行：
public List<RanChangeSet> getRanChangeSetList()
throws DatabaseException
{
if (this.ranChangeSetList != null) {
return this.ranChangeSetList;
}
String databaseChangeLogTableName = escapeTableName(getLiquibaseSchemaName(), getDatabaseChangeLogTableName());
this.ranChangeSetList = new ArrayList();
if (hasDatabaseChangeLogTable())
{
LogFactory.getLogger().info("Reading from " + databaseChangeLogTableName);
SqlStatement select = new SelectFromDatabaseChangeLogStatement(new String[] { "FILENAME", "AUTHOR", "ID", "MD5SUM", "DATEEXECUTED", "ORDEREXECUTED", "TAG", "EXECTYPE" }).setOrderBy(new String[] { "DATEEXECUTED ASC", "ORDEREXECUTED ASC" });
List<Map> results = ExecutorService.getInstance().getExecutor(this).queryForList(select);
for (Map rs : results)
{
***String fileName = rs.get("FILENAME").toString();***
