Thank you all for chiming in. Turns out the release was failing because I mistakenly placed extensions.xml in *<root>/.mvn/.mvn/extensions.xml* rather than *<root>/.mvn/extensions.xml 🤦*
Merging this pull request <https://github.com/jenkinsci/buildkite-plugin/pull/5> resulted in the successful release. Many thanks to Valentin <https://github.com/jonesbusy> for kindly pointing it out to me <https://github.com/jenkinsci/buildkite-plugin/pull/4#issuecomment-3162576565> .
