Error running Spring-Boot samples - spring-boot

Question

I've just cloned the github repo for Spring Boot samples, and I am trying to run various samples but they all return the same error:
c:\temp\spring-boot\spring-boot-samples\spring-boot-sample-web-jsp>mvn package

Have I missed anything? Do I need to add a repo for Spring Boot? The only Spring Boot artifacts in the main maven repo are all 1.1.5.RELEASE. If I replace 1.2.0.BUILD-SNAPSHOT with 1.1.5.RELEASE, it builds; but then unsurprisingly fails to run.

Answer 1

I ran into the same problem when I updated from 1.1.5.RELEASE.
I ran mvn install from the spring-boot directory.
It took over 1 hour 10 minutes!
Let me know if this fixes it!

Answer 2

Did you have the pom file pointing to the snapshot repo as in this link? The repo link has the maven plugin contents listed.
