Micrometer: NoClassDefFoundError with Spring Boot 1.5

[nugnoperku]

When using micrometer-legacy 1.1 with Spring Boot 1.5, I get the following error:

@nugnoperku This seems to happen with a corrupted org.latencyutils:LatencyUtils dependency. Could you try to remove it and make Maven download it again?

[nugnoperku]

I don't have it. It's a dependency of micrometer-core, but not micrometer-legacy.

https://mvnrepository.com/artifact/org.latencyutils/LatencyUtils/usages

[izeye]

@nugnoperku micrometer-spring-legacy depends on micrometer-core and you should have one in your Maven local repository.

Check the dependency as follows:

ls ~/.m2/repository/org/latencyutils/LatencyUtils

Remove the dependency as follows:

rm -rf ~/.m2/repository/org/latencyutils/LatencyUtils

@nugnoperku let us know if @izeye's suggestion doesn't resolve the issue. You can also come chat on our Slack (http://slack.micrometer.io) which might be easier/quicker than GitHub issues.
