Did you skip removing the -SNAPSHOT?

Did you skip removing the -SNAPSHOT?

@wanglinsong I removed -SNAPSHOT in this step

tempto/.github/workflows/release.yml

Line 51 in fb7aa8f

release_version=$(grep "^ext.tempto_version" build.gradle | cut -d"'" -f2 | sed 's/-SNAPSHOT//')

And committed it in this step

tempto/.github/workflows/release.yml

Line 91 in fb7aa8f

git commit -m "Update CHANGELOG.md and build.gradle for version ${{ env.release_version }}"
