maven - skip dependency during build-CodePudding

I want to skip demo-api (Which is another module) during build. Setting optional true doesn't work. Any suggestions on how to skip it but not delete the dependency from pom.xml?

Failed to execute goal on project [36mdemo-web[m: [1;31mCould not resolve dependencies for project demo-web:demo-web:war:1.0-SNAPSHOT: Failed to collect dependencies at demo-api:demo-api:jar:1.0-SNAPSHOT[m: Failed to read artifact descriptor for demo-api:demo-api:jar:1.0-SNAPSHOT: Could not find artifact demo-spring-boot:demo-spring-boot:pom:1.0-SNAPSHOT

    <dependency>
        <artifactId>demo-api</artifactId>
        <groupId>demo-api</groupId>
    <version>1.0-SNAPSHOT</version>
    <optional>true</optional>
    </dependency>

You can put that dependency in a profile:

<?xml version="1.0" encoding="UTF-8"?>

</project>

When you build this project:

$ mvn verify # this will succeed

$ mvn verify -PincludeBadDependency

Maybe this can give you a hint or two.

<scope>runtime</scope>

I think this will do the trick
