I'm using Spring Boot 2.7.7

Running 

mvn spring-boot:build-image

produces

It looks like this is causing the problem: https://spring.io/blog/2022/12/14/notice-of-permissions-changes-to-repo-spring-io-january-2023

Yes, that's the cause. The Paketo Spring Boot buildpack is attempting to download the Spring Cloud Bindings library. The problem will need to be resolved by those two projects. We'll work with those projects to come up with a solution.

FYI - A possible work around is available at https://github.com/paketo-buildpacks/spring-boot/issues/225#issuecomment-1186597162

@jeisinge Thanks. My workaround is to use a Dockerfile. This will be much more reliable.

There is a related Spring Cloud Bindings issue here: https://github.com/spring-cloud/spring-cloud-bindings/issues/71

And a Paketo Spring Boot buildpack issue here: https://github.com/paketo-buildpacks/spring-boot/issues/304

Similar download errors will happen for the following libraries when building images from a plain war file that requires Tomcat to run:

  • tomcat-access-logging-support
  • tomcat-lifecycle-support
  • tomcat-logging-support

See the Paketo Apache Tomcat buildpack issue here: https://github.com/paketo-buildpacks/apache-tomcat/issues/295
