This occurs during an upgrade process:


The appropriate jdbc driver (in this example the MySQL jdbc driver) has not been installed or copied from the old instance.


Copy the jdbc from your old installation to your new installation, or download the latest driver from the manufacturer's website. The driver can be found either at common/lib directory or confluence/WEB-INF/lib directory.

For MySQL, please see the complete list of steps to download and install the JDBC driver in this page.

  1. Just in case, I had similar problems. The way it worked out for me was:

    once you added the mysql driver jar to the build path,

    you have to add to the pom.xml the dependency.



    I hope it helps.

    EDITED: sorry, it was copy/paste error.

  2. what does "<version>5.1.6</version>" stand for?  I mean the 5.1.6?  because confluence version is  5.6.3 and the mysql cin.jar driver version is 5.1.33

    Also I don´t find this "<packaging>atlassian-plugin</packaging>" in the pom.xml file

    I can´t make it work, confluence setup will create all table in the DB but then nothing happens.
