So I read the documentation and it says addUniqueConstraint is supported for sqlite, however when I try to apply this change set I get and Error

&nbsp;&nbsp; &nbsp;

&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp;&nbsp; &nbsp;

&nbsp;1 changes have validation failures

&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;addUniqueConstraint is not supported on sqlite,

Any idea whats going on? I’m using liquibase 2.0.1 and sqlite3 (sqlite-jdbc-3.6.0.jar)
