title: Liquibase generateChangeLog is failing - with Table already exists
body: <p>I am getting a "table already exists" error from Liquibase when I run my Jhipster project:</p>
  
  <pre><code>[ERROR] liquibase - classpath:config/liquibase/master.xml: classpath:config/liquibase/changelog/db-changelog-001.xml::1::jhipster: Change Set classpath:config/liquibase/changelog/db-changelog-001.xml::1::jhipster failed.  Error: Error executing SQL CREATE TABLE fc.T_USER (login VARCHAR(50) NOT NULL, .....: Table 't_user' already exists
  </code></pre>
  
  <p>I have generated the Liquibase changelog file into config\liquibase\changelog directory using </p>
  
  <pre><code>liquibase --driver=com.mysql.jdbc.Driver ^
        --classpath=C:\Users\Greg\.IntelliJIdea13\config\jdbc-drivers\mysql-connector-java-5.1.31-bin.jar ^
        --changeLogFile=db-changelog-001.xml ^
        --url="jdbc:mysql://localhost/fc" ^
        --username=root ^
        generateChangeLog
  </code></pre>
  
  <p>So something is tricking Liquibase into trying to re-create the database when the changelog, I thought, was setting a baseline of the existing database.</p>
  
  <ul>
  <li>Jhipster version: When I yo jhipster -v is says 1.2. When I nmp update jhipster is says I am on the latest = 17.2</li>
  <li>Liquibase version  tried 3.0, 3.1 and 3.2</li>
  <li>Mysql database from XAMP</li>
  <li>2 tables are created in Mysql - databasechangelog and databasechangeloglock</li>
  <li>databasechangelog remains empty and databasechangeloglock has a record added when Jhipster app is run</li>
  </ul>
  
  <p>This process was working but not since move to new computer. When it was working I saw databasechangelog had a couple of records in it as well as 1 in databasechangeloglock </p>
  
  <p>Tips on how to debug as welcome as an answer. Thanks.</p>
