Micrometer: java.lang.NoSuchMethodError: io.micrometer.core.instrument.MeterRegistry$Config.onMeterRemoved

[benemon]

Attempting to instrument a Vert.x application with Micrometer 1.1.1.

Setting the VertxOptions object via a custom launcher:

@Override
    public void beforeStartingVertx(VertxOptions options) {
        MicrometerMetricsOptions prometheusOptions = new MicrometerMetricsOptions()
                .setPrometheusOptions(new VertxPrometheusOptions().setEnabled(true))
                .setEnabled(true);

        options.setMetricsOptions(prometheusOptions);

        super.beforeStartingVertx(options);
    }

leads to the error in $Subject. Full stack trace is as follows:

pom.xml contains the following micrometer references:

        <dependency>
            <groupId>io.vertx</groupId>
            <artifactId>vertx-micrometer-metrics</artifactId>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.1.1</version>
        </dependency>

I assume I'm just missing something here, but not sure what...

Make sure that 'vertx-micrometer-metrics' is pulling in the same 'micrometer-core' version as you requested with the 'micrometer-registry-prometheus' dependency. Likely it isn't '1.1.1'. The first dependency wins being nearer to the dependency root.

Yup that was it, thanks. Thought it'd be something simple.
