Quarkus Example of Reactive Panache with reactive postgres client not working with gradle

[TheoCadoret]

Describe the bug

When I run the example in https://quarkus.io/guides/getting-started-reactive but with gradle instead of maven, I get the error :

java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors [error]: Build step io.quarkus.agroal.deployment.AgroalProcessor#build threw an exception: io.quarkus.runtime.configuration.ConfigurationException: Unable to find a JDBC driver corresponding to the database kind 'postgresql' for the default datasource. Either provide a suitable JDBC driver extension, define the driver manually, or disable the JDBC datasource by adding 'quarkus.datasource.jdbc=false' to your configuration if you don't need it. at io.quarkus.agroal.deployment.AgroalProcessor.resolveDriver(AgroalProcessor.java:331) at io.quarkus.agroal.deployment.AgroalProcessor.getAggregatedConfigBuildItems(AgroalProcessor.java:277) at io.quarkus.agroal.deployment.AgroalProcessor.build(AgroalProcessor.java:82) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at io.quarkus.deployment.ExtensionLoader$2.execute(ExtensionLoader.java:820) at io.quarkus.builder.BuildContext.run(BuildContext.java:277) at org.jboss.threads.ContextHandler$1.runWith(ContextHandler.java:18) at org.jboss.threads.EnhancedQueueExecutor$Task.run(EnhancedQueueExecutor.java:2449) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1478) at java.base/java.lang.Thread.run(Thread.java:829) at org.jboss.threads.JBossThread.run(JBossThread.java:501)

Expected behavior

Well, I think it should work

Actual behavior

No response

How to Reproduce?

Proceed with the tutorial at https://quarkus.io/guides/getting-started-reactive but use gradle instead.

Then run gradle build -x test (otherwise it fails for something else not relevant here) and you should see it.

Additional information

Actually, within my project where it first failed, I was using a simple async pg client to run my queries. Simply adding the reactive panache extension without using it was enough to make the stacktrace appear.

Thanks for reporting this @TheoCadoret.
#21019 takes care it and should available in 2.5.0.
as a workaround, you can add the following exclude:

configurations.all {
  exclude(group = "io.quarkus", module = "quarkus-agroal-deployment")
}

Wow that was quick !
The workaround seems to be working, thank you very much for your helpful response !
