Description

Since v7.23.0, openapi-generator-cli-{version}.jar is no longer attached to the
GitHub Release assets, even though the upload-release-asset job was added in #23524
(closing #23519).

Release	JAR asset
v7.21.0	present
v7.22.0	present
v7.23.0	missing
v7.24.0	missing

GitHub-Release-based version managers such as aqua cannot install v7.23.0 / v7.24.0, so installation fails in CI for projects that pin those versions.

openapi-generator version

v7.23.0 and v7.24.0 (regression; v7.22.0 and earlier have the asset).

OpenAPI declaration file content or url

N/A - this is a release/CI issue, not a code generation issue.

Steps to reproduce

1. Open https://github.com/OpenAPITools/openapi-generator/releases/tag/v7.24.0
2. Observe that no openapi-generator-cli-7.24.0.jar asset is listed.
3. Compare with https://github.com/OpenAPITools/openapi-generator/releases/tag/v7.22.0, which has the asset.
