Error building sample-functions-framework-java-mvn

[oliverhenlich]

I've tried everything I can think of to try and get this example to work. But nothing seems to work. Any suggestions would be greatly appreciated.

Steps:

• Clean checkout
• cd sample-functions-framework-java-mvn
• ./mvnw clean package
• pack build --builder gcr.io/buildpacks/builder:v1 sample-functions-java-mvn --verbose

Error:

[detector] ERROR: No buildpack groups passed detection.
[detector] ERROR: failed to detect: buildpack(s) failed with err
ERROR: failed to build: executing lifecycle: failed with status code: 21

Environment info:
