Great. Thanks! Do we have an example that shows how to run a Wasm program from Java such as these?

https://github.com/WasmEdge/WasmEdge/blob/master/docs/run.md

This PR is a basic setup for Java SDK. And it only contains the getVersion feature. I don't think it can run a Wasm program at the current stage.

[kenvifire]

@juntao @hydai This PR is still WIP. I'll let you guys know once it's completed done.

[kenvifire]

@juntao @hydai Most part are done, please help review this MR. I'll continue working on the rest part.

[hangedfish]

Cool, is there a preview in the Maven repository? I can't wait to try it.

[kenvifire]

@hydai Sure, I can do it. Can you provide an example for reference?

[hydai]

This is the rust binding workflow: https://github.com/WasmEdge/WasmEdge/blob/master/.github/workflows/bindings-rust.yml Basically, it will contain the building process and the testing process at least in the Linux environment.

[kenvifire]

@hydai Updated API to the latest and also added CI workflow following your suggestion. Can you please take a look?

[hydai]

Hi @kenvifire I found there are some warnings in https://github.com/WasmEdge/WasmEdge/actions/runs/3258891835/jobs/5351315117#step:8:1

These warnings may be big issues if the users build it with -Werror, could you please fix them?

[kenvifire]

@hydai fixed warnings.

[hydai]

Hi @kenvifire I and @dannypsnl will start to review the remaining implementations. It will take some time, but I think we can finish it this week.

[dannypsnl]

@kenvifire You would need to signoff every commit, maybe an alias git command to commit -s would help.

[kenvifire]

@dannypsnl Can we merge this PR first? So that we can have others working on this feature at the same time.

[kenvifire]

@hydai I've got one approval, what's the next step for merging this pull request?

[hydai]

Thank you @kenvifire Nice work.

[kenvifire]

Thank you @kenvifire

Nice work.

Cheers! By the easy, I'm still working on other features, ci and some code refactoring. Is there any way I can track my work? Or can I just create some issues to track them?

[hydai]

Hi @kenvifire It would be better to have an issue recording your milestones.

Hi @kenvifire It would be better to have an issue recording your milestones.

Created an issue: https://github.com/WasmEdge/WasmEdge/issues/2025. Can you please assign it to me? Thanks.
