4.x: MP quickstart archetype has unnecessary metrics dependencies

[barchetta]

• Helidon Version: 4.0.0-RC1
• Helidon MP

---

Problem Description

Generate a 4.0.0-RC1 MP quickstart using the CLI and the pom.xml has:

        <dependency>
            <groupId>io.helidon.metrics</groupId>
            <artifactId>helidon-metrics</artifactId>
            <scope>runtime</scope>
        </dependency>

And

        <dependency>
            <groupId>io.helidon.metrics</groupId>
            <artifactId>helidon-metrics</artifactId>
        </dependency>

I don't think it should have either of these.

I believe Joe is correct here.

At one point we planned to use bundles such as helidon-metrics but, at least for now, we have moved away from that.

For MP, depending on helidon-microprofile-metrics and org.eclipse.microprofile.metrics:microprofile-metrics-api should be what we want for API dependencies. The MP QuickStart depends on the full Helidon MP bundle which includes those already.

And (as we've discussed earlier), these need to be present also:

        <dependency>
            <groupId>io.helidon.webserver.observe</groupId>
            <artifactId>helidon-webserver-observe-metrics</artifactId>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>io.helidon.metrics</groupId>
            <artifactId>helidon-metrics-system-meters</artifactId>
            <scope>runtime</scope>
        </dependency>
