BitBucket Server says com.mysql.jdbc.Driver is not available even though the jar is there

I've just upgraded our BitBucket Server to 5.2.2 and it won't start with an error message: "The database, as currently configured, is not accessible. Bitbucket is configured to use the mysql driver (com.mysql.jdbc.Driver) but it is not available.".


This is not the first time I was upgrading the BitBucket Server. As it was with the last time I was upgrading it, I've put the latest jdbc driver (mysql-connector-java-5.1.43-bin.jar) in the /opt/atlassian/bitbucket/5.2.2/lib folder. It doesn't matter if I start it with service atlbitbucket start or 5.2.2/bin/ commands, the error is always there.

Is this a known issue and can it be resolved?

The lib folder was moved to /var/atlassian/application-data/bitbucket/lib, placing the mysql-connector-java-5.1.43-bin.jar file there solved the issue.

I suggest Atlassian team to update the page Connecting Bitbucket Server to MySQL with a note that informs that from Bitbucket 5.x by default home dir in linux envs has been moved in /var folder.

Had to figure this out for Windows Server 2008 R2 Sp1 - we were getting the same error when trying to launch it in the browser. With a default install of Bitbucket 5.x the path is apparently:

(where you find the other .jar files). Once we copied the connector there, it worked out.

Thanks Spencer, worked perfectly... Updated docs are needed.

Will there any help with this?

It also works if the sql connector jar file is copied to 


The advantage is that the customisation will persists across upgrades.
