Cloning this project: https://github.com/oscarfh/micronaut-gen-bug-report
(This is a project that was generated from Micronaut's page and had the micronaut generator configured with the default values)
Then run ./gradlew openApiGenerate --stacktrace
You will get the following stacktrace:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':openApiGenerate'.

Changing the openApiGenerate openAPI task configuration to
openApiGenerate {
generatorName = "micronaut"
inputSpec = "${projectDir}/src/main/resources/api.yaml"
outputDir = buildDir.toString()
configOptions = [
dateTimeRelaxed: "false"
]
}
builds the project without problems.
