First, thank you for your ongoing support for Cloudbeaver CE

Is your feature request related to a problem? Please describe.

I am having issues accessing/creating connections to this driver.
I was able to follow your build instructions starting with the following OS setups/base images:

  • Minimal Ubuntu 20.04.
  • maven:3.9.0-eclipse-temurin-17-focal docker image

In both cases I am able to build and deploy the server that includes the duckdb driver. This is how my final artifacts look like:

~/cloudbeaver/deploy$ ls -ltrh

total 54M
-rw-r--r-- 1 54M Apr 11 14:46 duckdb_jdbc-0.7.1.jar

After deploying/running server, when I try to create a new DB connection (or accessing the driver properties) with duckdb I get the following errors:

From GUI dialog:

Describe the solution you'd like

I only found this closed issue https://github.com/dbeaver/cloudbeaver/issues/1159 in relation to DuckDB driver.

I appreciate your assistance with this error. Perhaps, even better if you are able to include DuckDB driver in one of the releases in Docker Hub.

Thank you.

Please describe.* I am having issues accessing/creating connections to this driver. I was able to follow your build [instructions](https://github.com/dbeaver/cloudbeaver/wiki/Adding-new-database-drivers#Drivers-and-bundles) starting with the following OS setups/base images: * Minimal Ubuntu 20.04. * maven:3.9.0-eclipse-temurin-17-focal docker [image](https://hub.docker.com/layers/library/maven/3.9.0-eclipse-temurin-17-focal/images/sha256-134f6a7fbe271d6ee18e92e013a94e5367b9d3ca8de440de648c7089143a5fd5?context=explore) In both cases I am able to build and deploy the server that includes the duckdb driver. This is how my final artifacts look like: ```shell ~/cloudbeaver/deploy$ ls -ltrh total 16K drwxr-xr-x 1 32 Apr 11 14:33 supervisor drwxr-xr-x 1 54 Apr 11 14:33 scripts drwxr-xr-x 1 170 Apr 11 14:33

duckdb I get the following errors: #### From GUI dialog: ``` Error connecting to database: Connection failed: Can't create driver instance java.lang.ClassNotFoundException: org.duckdb.DuckDBDriver at

I appreciate your assistance with this error. Perhaps, even better if you are able to include DuckDB driver in one of the releases in Docker Hub. Thank you.
