I want use Unitils for testing my JAVA program, i have following error message "UnitilsException: Executed scripts table "PUBLIC"."DBMAINTAIN_SCRIPTS" doesn't exist yet or is invalid"

My table is into an DDL file, and table is not created

Could you says me if dataSetStructureGenerator.xsd.dirName=src/test/resources/dataset-schema properties is still active in unitils 3.3 ?

My EMPLOYEE table is not created and DBMAINTAIN_SCRIPTS not created too Where is my mistake ?

My DDL file

SET REFERENTIAL_INTEGRITY FALSE;
SET DATABASE COLLATION "French";
SET SCHEMA PUBLIC;
CREATE TABLE DBMAINTAIN_SCRIPTS (FILE_NAME VARCHAR2(150), FILE_LAST_MODIFIED_AT INTEGER, CHECKSUM VARCHAR2(50), EXECUTED_AT VARCHAR2(20), SUCCEEDED INTEGER);
CREATE TABLE EMPLOYEES(ID IDENTITY NOT NULL,NAME VARCHAR(20),TITLE VARCHAR(20),SALARY DOUBLE,NI INTEGER NOT NULL) 

My unitils properties file

# brevity. look for commenting in unitils-default.properties in the root of the
# unitils jar if needed.
