Eu tenho um modelo de classe UML modelio. Eu o atualizo o tempo todo e, depois disso, corro o jhipster-uml .xmi para regenerar entidades. Eu sempre acabava com mensagens de erro. Tentei excluir dos arquivos -jhipster os arquivos entity.json, mas isso não ajuda. Então, você poderia me dizer qual é a solução alternativa correta para atualizar entidades durante o desenvolvimento? Tentei executar a tarefa maven: diff também, mas sem sorte.

EDITAR:

Criei um novo aplicativo jhipster e criei entidades a partir do modelo de classe UML modelio. Tudo está funcionando bem. Acabei de adicionar um atributo ao meu modelo e regenerar a entidade do arquivo xmi e tudo será quebrado novamente.

Meu fluxo de trabalho foi: 1) salve o modelo uml como arquivo xmi 2) Execute jhipster-uml ac2.xmi -paginate 3) Compile meu aplicativo no intellijIdea 4) execute tarefa maven: mvn compile liquibase: diff para criar um novo changelog 5) execute aplicação 6) Assista às mensagens de erro:

      classpath:config/liquibase/changelog/20150828220237_added_entity_Employee.xml::20150828220237::jhipster is now: 7:dd10f74a01a95b4e48c592e796a1d352
