Hi all,

We are currently upgrading our self-hosted BRXM instances from 15.1.4 to 15.2.2. We followed the upgrade guides ([generic](https://xmdocumentation.bloomreach.com/about/upgrade/minor-upgrades.html), and [version specific](https://xmdocumentation.bloomreach.com/library/upgrade-minor-versions/upgrade-15.1-to-15.2.html)) and the Docker build completes successfully.

However, the BRXM 15.2.2 Docker container fails to run, giving the following error:

```auto
b2beu-brxm> cp: cannot stat '/brxm/db-drivers/mysql/.': No such file or directory

```

When looking at the files of the BRXM 15.2.2 container we can see that only the PostgreSQL driver is there:

```auto
brxm/db-drivers/
brxm/db-drivers/postgres/
brxm/db-drivers/postgres/postgresql-42.2.5.jar

```

Whereas the BRXM 15.1.4 container does have the MySQL driver file:

```auto
brxm/db-drivers/
brxm/db-drivers/mysql/
brxm/db-drivers/mysql/mysql-connector-java-8.0.16.jar
brxm/db-drivers/postgres/
brxm/db-drivers/postgres/postgresql-42.2.5.jar

```

The only files that we updated for the upgrade are the following:

```auto
cms-depe‎ndencies‎/pom‎.xml‎ (`hippo-addon-urlrewriter-module-repository` to `hippo-addon-urlrewriter-cms-dependencies`)
site/co‎mponents/‎pom‎.xml‎ (`hippo-addon-urlrewriter-module-hst` to `hippo-addon-urlrewriter-site-dependencies`)
pom.xml‎ (`hippo-cms7-enterprise-release` version change)

```

Did we miss any steps? Any help would be appreciated, thanks in advance!

Hi,  
I can’t pinpoint it right now but this probably has to do with using the new Maven coordinates `com.mysql:mysql-connector-j`, see [https://issues.onehippo.com/browse/CMS-15288](https://issues.onehippo.com/browse/CMS-15288)

Thanks for the really quick response, Jeroen! The new Maven coordinates were indeed causing the problem.

The fix:

1. Open `docker-db-libs.xml`
2. Change `mysql:mysql-connector-java` to `com.mysql:mysql-connector-j`
