Trouble getting javalin-openapi to produce any output?

Hey, could you share your Gradle/Maven config? It looks like misconfigured annotation processor.

Thanks for looking at it! Sounds like a plausible diagnosis :-)

The pom file is here:
https://github.com/Convex-Dev/convex/blob/develop/convex-restapi/pom.xml

FWIW, I'm building on Windows using Eclipse and Maven 3.9.4

And here is what I believe is the relevant annotation processor plugin:

	<build>
		<plugins>
			....
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.12.1</version>
				<configuration>
					<source>11</source>
					<target>11</target>
					<annotationProcessorPaths>
						<annotationProcessorPath>
							<groupId>io.javalin.community.openapi</groupId>
							<artifactId>openapi-annotation-processor</artifactId>
							<version>${javalin.version}</version>
						</annotationProcessorPath>
					</annotationProcessorPaths>
				</configuration>
			</plugin>
		</plugins>
	</build>

I'm not entirely clear where the openapi json is supposed to be put by default?

The Javalin server isn't particularly complex, though it does have a static file handler and a few API endpoints set up as well as the OpenAPI plugin with ReDoc and Swagger.

Hey, sorry, I totally missed the notification as I have quite a lot of them 😔 Just cloned your project and it looks fine for me:

I think the issue here is probably Eclipse - I assume that you're probably launching your app via some sort of their custom app runner, where annotation processing is disabled by default, so I'd start looking there. I guess you can start from something like this:

Thanks for checking @dzikoysk ! Will see if I can figure out what Eclipse is doing....
