I am having trouble with liquibase. When I run my J2EE application, liquibase tells me : 

liquibase.exception.ValidationFailedException: Validation Failed:
     1 change sets check sum
          classpath:config/liquibase/changelog/20160324155624_added_entity_Consultant.xml::20160324155624::jhipster is now: 7:30bd20fc51a6e6711ba189760c980415

I don't remember having changed the Consultant entity. So I don't understand why I am having this error.

If someone can tell in which case this type of error occurs... Because I don't really understand its meaning.

Thank you.

  • Did you move the changelog files into a different dir? I think the path is part of the checksum. Or maybe you just execute liquibase from a different Computer where the files are stored in a different path? – Jens Apr 29 '16 at 12:20
  • I didnt' change anything. If I change the content of the file, can this change create that kind of issue? – user1260928 Apr 29 '16 at 12:26
  • Yes it can. Once the change was run on your database you're not supposed to change it anymore. – Jens Apr 29 '16 at 13:08
  • You can clear the checksums if you want to and if you're confident. See this [answer](http://stackoverflow.com/a/10000393/332248) – Jens Apr 29 '16 at 13:09

If your change set loads a file using the <loadData file=someFile.csv /> tag then liquibase will also include that file's contents in the checksum calculation. So any change to someFile.csv will change the checksum of your changeset, even though your changeset hasn't changed.
