Hey @xespirit, which version are you using?
I am pretty sure this is an old bug from Modelina v2
In v3 I get the following (https://modelina.org/playground?language=java):

Hey @xespirit, which version are you using?

I use 4.0.0-next.16 version of modelina:
"dependencies": {
"@asyncapi/modelina": "^4.0.0-next.16",
"ts-node": "^10.9.2",
"typescript": "4.9.5"
},
Ehh. Let me take a look with next
🤔
@xespirit even with next when I use the following AsyncAPI document it works fine (https://65f02a20166dac9eadcc846e--modelina.netlify.app/playground?language=java):

Might have something to do with your $ref
pointing to the file itself 🤔 Is there a more complex setup in place that might cause this?

Yes, it has something to do with $ref pointing to itself. There's no any complex setup. I have tried Modelina generator with different json schemas, with different complexity. Everything works well except for case I mentioned above.
Is there any default behaviour of generator so It gneerates Map<String, Object> witjhout even including Java import for Map. My guess it happens when the generator gets confused so it somehow generates the map instead of correct object type.
Damn, yea thats a bug! https://github.com/asyncapi/modelina/blob/1239c9a03c1cccccd20ef9fd987219ee9d54107f/src/generators/java/JavaConstrainer.ts#L238
We need to add the dependency import like we do for Python here: https://github.com/asyncapi/modelina/blob/1239c9a03c1cccccd20ef9fd987219ee9d54107f/src/generators/python/PythonConstrainer.ts#L20
Do you mind helping to fix this?

I'm sorry but I'm Java/Kotlin Back-end developer, I don't think I have capacity right now to fix Typescript codebase
No worries, created a good first issue for it: https://github.com/asyncapi/modelina/issues/1892

Regarding this problem, I simply cant reproduce your problem, unfortunately... Cause the example you gave generates the correct models.
Can you reproduce it yourself on the playground and post the example? https://65f02a20166dac9eadcc846e--modelina.netlify.app/playground?language=java
Hey @jonaslagoni I would love to work on it.
However, Same stands for me as well; I am also unable to generate this problem in playground, I am still wondering why that
If the Change is this only, then why only this specific case isn't importing map. It's weird.

It's for every case, where there is a dictionary model 🙂

I'm providing full sets of files to reproduce the issue:
Case.json DirectPolicy.json Insurance.json Policy.json Schemas.json
The generator is being called from Maven plug-in:
generate ./node_modules/.bin/ts-node ./generate.ts com.test.asyncapi.model model/Schemas.json target/generated-sources/asyncapi/com/test/asyncapi/model
I've attached pictures of generated files, representing the issue below:
@jonaslagoni could you try to reproduce the bug?
As you can see Modelina generator thinks all files are generated successfuly (without exiting with error). But in fact we have:
@JsonProperty("exceptForCase")
@JsonInclude(JsonInclude.Include.NON_NULL)
private List<Map<String, Object>> exceptForCase;
and exceptForCase shouldn't be a list of Map<String, Object>. Expected result is a
private List<CaseSchema> exceptForCase;
Just pinging that I have not forgotten about this, but have to work on some other fixes that I think will fix this along side it.
This issue has been automatically marked as stale because it has not had recent activity :sleeping:
It will be closed in 120 days if no further activity occurs. To unstale this issue, add a comment with a detailed explanation.
There can be many reasons why some specific issue has no activity. The most probable cause is lack of time, not lack of interest. AsyncAPI Initiative is a Linux Foundation project not owned by a single for-profit company. It is a community-driven initiative ruled under open governance model.
Let us figure out together how to push this issue forward. Connect with us through one of many communication channels we established here.
Thank you for your patience :heart:
Describe the bug.
Modelina Async generator fails to generate Java class correctly in certain scenario: there's self-refence. Example:
Expected behavior
Generated Java class should have
private List<CaseSchema> exceptForCase;
instead it generates array of Map<String, Object>:
private List<Map<String, Object>> exceptForCase;
Screenshots
Example:
Generated class:
