Micrometer: java.lang.ClassNotFoundException: io.micrometer.core.instrument.stats.quantile.Quantiles

Getting java.lang.ClassNotFoundException: io.micrometer.core.instrument.stats.quantile.Quantiles exception when using spring-boot-actuator-starter and setting up a data source.

version used:
org.springframework.boot.spring-boot-starter-actuator:2.1.7.RELEASE

also worth noting:
As a transitive dependency, I already load
io.micrometer.micrometer-registry-prometheus:1.1.1

Does anyone have a clue what I am doing wrong, or how to fix this exception?

I was using:

        <dependency>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
            <version>2.7.2</version>
        </dependency>

now I switched to:

        <dependency>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
            <version>3.3.1</version>
        </dependency>

which seems to have solved the problem.

Thanks for your help guys, I appreciate it.

@gorjan-bux I suspect you have a corrupted jar for the io.micrometer:micrometer-core dependency in your cache. Please try deleting the jar in the cache and then start your application again.

@gorjan-bux Sorry, I overlooked the class which has triggered the ClassNotFoundException. Ignore the first comment. There's no io.micrometer.core.instrument.stats.quantile.Quantiles in io.micrometer:micrometer-core:1.1.1. Based on the stack trace, it seems you're using HikariCP which is not compatible with Micrometer.

@izeye Thanks for the fast response.
For some reason we are using a custom version HikariCP, and I will investigate this further and post an update.

For some reason we are using a custom version HikariCP, and I will investigate this further and post an update.

Micrometer integration should work well with official versions of HikariCP.
Your stacktrace doesn't match with the HikariCP source: https://github.com/brettwooldridge/HikariCP/blob/086bf18389282d1a7484e243d6af49890cec4fd7/src/main/java/com/zaxxer/hikari/metrics/micrometer/MicrometerMetricsTrackerFactory.java

If you can use official versions of HikariCP, that would be best.
