Js java object user request

[ake2l]

I seem to get an error also during this instruction:
importPackage(com.rapiddweller.model.data);
Would there be another way of doing these imports inside the execute block? The error really that appears is that the first variable I have created, that "it has already been created". Seems unrelated.
If I remove the "importPackage" instruction, I don't have any error

He is following the 1.1.1 docs example: https://docs.benerator.de/1.1.0/scripting.html

<setup>
  <database id="db" url="jdbc:hsqldb:mem:example" driver="org.hsqldb.jdbcDriver" user="sa" schema="PUBLIC"/>

  <execute type="js">

  importPackage(com.rapiddweller.model.data);

  print('DB-URL' + db.getUrl());

  // create user Alice var alice = new Entity('db_user'); alice.set('id', 1); alice.set('name', 'Alice'); db.store(alice);

  // create user Bob var bob = new Entity('db_user', 'id', '2', 'name', 'Bob'); db.store(bob);

  // persist everything db.flush();

  </execute>
</setup>
