Gradle tests appear to be failing

[geoand]

Describe the bug
When one runs the gradle tests locally using

/gradlew clean test -i -S --stacktrace --no-daemon

from integration-tests/gradle,

one sees various error that boil down to:

Caused by: javax.enterprise.inject.spi.DeploymentException: No config value of type [java.lang.String] exists for: quarkus.application.version
	at io.quarkus.arc.runtime.ConfigRecorder.validateConfigProperties(ConfigRecorder.java:39)
	at io.quarkus.deployment.steps.ConfigBuildStep$validateConfigProperties1249763973.deploy_0(ConfigBuildStep$validateConfigProperties1249763973.zig:158)
	at io.quarkus.deployment.steps.ConfigBuildStep$validateConfigProperties1249763973.deploy(ConfigBuildStep$validateConfigProperties1249763973.zig:40)
	at io.quarkus.runner.ApplicationImpl.doStart(ApplicationImpl.zig:455)

Expected behavior
No test failures

Actual behavior
Various test failures, the should have been caught in CI
