Adding new database drivers

CloudBeaver supports many popular databases out of the box.
But sometimes you need to add a new driver - less popular of even some custom driver developed inside your company.

This instruction describes how you can do it.


CB is based on DBeaver platform. It reuses drivers provided by DBeaver plugins.
Thus you can not add a driver which is not configured in some of DBeaver plugins.

Out of the box DBeaver supports more than 50 different database drivers. Some of them pre-configured in CloudBeaver as well, some are not.
Generally adding new driver in CB consists of two steps:

  1. Add driver in DBeaver
  2. Configure this driver in CloudBeaver

If driver already included in DBeaver then you can skip the first step.

What is special about CloudBeaver comparing to DBeaver?

DBeaver downloads database drivers (JDBC) on demand (after the first attempt to connect to the database). This approach doesn't work in case of CloudBeaver. Mostly because driver download may require some user interactions + access to external resources + some local file system permissions.
CloudBeaver must have all driver jars pre-downloaded in the folder set as driversLocation in the Server configuration. By default is is a directory drivers in the root of CloudBeaver deployment.

Configuring drivers in DBeaver

Usually driver descriptions are located in DBeaver's plugin.xml files. You can search string <driver there and find a bunch of examples.
Like this:

    <extension point="org.jkiss.dbeaver.dataSourceProvider">
        <datasource id="postgresql" label="PostgreSQL" ...>

            <drivers managable="true">
                    <file type="jar" path="maven:/org.postgresql:postgresql:RELEASE[42.2.5]" bundle="!drivers.postgresql" />
                    <file type="jar" path="drivers/postgresql" bundle="drivers.postgresql" />

                    <parameter name="serverType" value="postgresql" />
                    <property name="loginTimeout" value="20" />
                    <property name="connectTimeout" value="20" />

It is actual PostgreSQL driver definition (irrelevant configuration elements were skipped).
Full driver ID is postgresql.postgres-jdbc. It is combined from two parts: data source provider ID and driver definition ID.

Note: for most non-standard driver you must add new driver definition to Generic plugin (org.jkiss.dbeaver.ext.generic) because it works with plain JDBC API only.

Adding driver definition in UI (optional).

You can add new driver configuration manually in the plugin.xml. But you also can generate this configuration in DBeaver user interface.

Adding of custom drivers configuration in the UI is described here: Database Drivers.
After that you can find you driver definition in the drivers.xml (see Administering drivers). Then you can copy it into the appropriate plugin.xml file.


All drivers need some 3rd party jar files (actual driver executable code).
For CloudBeaver 3rd party jars must be in some public Maven repository (Maven Central is preferred). Line

<file type="jar" path="maven:/org.postgresql:postgresql:RELEASE[42.2.5]">

refers to external Maven artifact which must contain driver jar files.

Drivers and bundles

In the driver definition example (see above) you can see two lines:

<file type="jar" path="maven:/org.postgresql:postgresql:RELEASE[42.2.5]" bundle="!drivers.postgresql" />
<file type="jar" path="drivers/postgresql" bundle="drivers.postgresql" />

First one refers to the actual Maven artifact. Second one refers to some weird path drivers/postgresql. What does it mean?
DBeaver Community doesn't contain any drivers' jars, it downloads them on demand. But DBeaver EE and CloudBeaver and other products may contain drivers out of the box so users won't need to download them.
These two lines configure driver for these two different situations. If you don't plan to include your driver configuration in DBeaver then you may skip the first line.

Testing and contributing (optional)

After you added your new driver in plugin.xml you must be able to connect to your database in DBeaver UI by choosing your new driver in the new connection wizard:

  • Build DBeaver desktop app (run mvn clean package in the root folder).
  • Run dbeaver executable in product/standalone/target/products/.../dbeaver folder (path differs for different OSes).
  • Open "New Connection" wizard. Configure your connection and click the "Test Connection" button.

If everything is fine then you can create a Pull Request and contribute your changes in the main DBeaver repository. This part is optional, you can leave everything in your local version or your forked version of DBeaver. In this case you will need to fix CloudBeaver build script (default build script uses main dbeaver repository as platform source code).

Adding drivers in CloudBeaver

You need to configure driver in CloudBeaver separately. Because it doesn't include all existing drivers from DBeaver.

Adding Maven artifact(s)

You must include driver in the server build. All 3rd party jars must be available to the server during startup. By default CB buidl script downloads 3rd party jars from Maven Central but you can add some custom logic there.

  • Explore directory server/drivers.
  • Create new sub-folder new-driver-id. You can copy-paste some existing driver directory for simplification.
  • Add pom.xml file in the new directory. It is a standard Maven pom, it can look like this:
    <project xmlns="" xmlns:xsi="" xsi:schemaLocation="">
  • Add you new driver id (equals to the new directory name) to the main server/drivers/pom.xml in the <modules> section.

Include driver in server configuration

  • Open file server/bundles/io.cloudbeaver.resources.drivers.base/plugin.xml
  • Add line <resource name="drivers/new-driver-id" /> in the end of other resource references. It will tell CloudBeaver where to find your new driver's jars.
  • Add line <bundle id="" label="New driver files" /> in the end of bundle list. See bundle configuration description for explanation.
  • Add line <driver id="full-driver-id" /> in the end of enabled drivers list. Usually your full driver id will be something like

That's it.

Deploy and test

See Build and deploy. Then just run script in the folder deploy. You will get your brand new driver included in the CloudBeaver server configuration.
Start the server. Examine log files - if something went wrong then you will see warnings or error messages in the server log.
