After upgrading Micronaut Gradle plugin from 3.2.2 to 3.3.0 fat-JAR application launch crashes with No bean of type [io.micronaut.context.event.ApplicationEventPublisher<io.micronaut.context.event.StartupEvent>] exists

[drmoeller]

Expected Behavior

Application should launch smoothly like before the upgrade.

Actual Behaviour

Application's Single-JAR is currently built using following plugin:
id('com.github.johnrengelman.shadow') version '7.+'

After upgrading Gradle Micronaut plugin from
id('io.micronaut.application') version '3.2.2'
to
id('io.micronaut.application') version '3.3.0'
launching the Single-JAR application like so
java -jar build/libs/application-0.1-all.jar
breaks with

10:16:17.436Z [   main] ERROR - Error starting Micronaut server: No bean of type [io.micronaut.context.event.ApplicationEventPublisher<io.micronaut.context.event.StartupEvent>] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).

reproducibly.

With enabled trace logging (as requested) the following message appears just in front of the one cited above:

DEBUG - Bean [foo.bar.baz.$OrderStatePublisherHttpClientImpl$Definition$Intercepted$Definition] will not be loaded due to failing conditions:

Also explicit addition of mentioned library with Kotlin APT via kapt('io.micronaut:micronaut-inject-java') doesn't help.

None of the application's types explicitly implement mentioned interface io.micronaut.context.event.ApplicationEventPublisher<io.micronaut.context.event.StartupEvent>.

After switching back to id('io.micronaut.application') version '3.2.2' app launches smoothly (with lots of messages regarding bean conditionals due to enabled trace logging of this feature).

Steps To Reproduce

See above.

$ ./gradlew clean assemble && java -jar build/libs/application-0.1-all.jar

Environment Information

• JRE 17.0.2
• Kotlin 1.6.10
• Gradle 7.4.1
• Micronaut 3.3.4

Example Application

No response

Version

3.3.4

Bug is not specific to Kotlin, also happens with Java.

[melix]

Workaround is to add:

tasks.withType(ShadowJar.class).configureEach(ShadowJar::mergeServiceFiles)

to your build script

[drmoeller]

Thanks for immediate reaction, including workaround.

It stills fails for Application Type: Serverless Function and Micronaut Gradle Plugin library.

#407 applies to MicronautMinimalApplicationPlugin but not MicronautMinimalLibraryPlugin
