The constraints are verified to ensure they can all be fulfilled.
If you have a service requirement, you need a matching service capability. So
instead of deploying your datasource using a simple config file, you should
write a feature:
{code:xml}
<feature name="the-jdbc-config">
<config pid="org.ops4j.datasource-test">
osgi.jdbc.driver.name=H2
databaseName=test
user=sa
password=
dataSourceName=testds-h2
</config>
<capability>
osgi.service;objectClass=javax.sql.DataSource;osgi.jndi.service.name=testds-h2
</capability>
</feature>
{code}
I haven't tested the above, but that's the idea.
An alternative would be to ensure that your jar has no Require-Capability
header in the manifest.

> Key: KARAF-5564
> URL: https://issues.apache.org/jira/browse/KARAF-5564
> Project: Karaf
> Issue Type: Bug
> Components: karaf-feature, karaf-kar
> Affects Versions: 4.1.4
> Reporter: Olga Kulikova
> Assignee: Jean-Baptiste Onofré
> Priority: Major
>
> I am not able to install feature that contains a jar that has a dependency on
> some jndi service, that is already available in karaf.
> Here is a simple example to demonstrate the problem:
> https://github.com/ol2ka/karaf-example
> The project contains 3 modules:
> # example-runtime - karaf assembly that contains configured h2 datasource
> # example-jar - bundle that has a dependency on this datasource
> # example-feature - feature that includes example-jar bundle.
> If I deploy example-jar directly, it works.
> If I try to deploy example-feature, I get an exception:
> {noformat}
