How to bind plugin mojos (goals) to few phases of default lifecycle?

Question

My custom maven plugin have three goals (mojos):

• convert assigned to default phase: process-test-resources
• generateStubs assigned to default phase: package
• generateTests assigned to default phase: generate-test-sources

How to bind this three mojo to default lifcycle phase, so the user can simply use plugin without special configuration and any changes to project packaging?

User should simply add:

<plugin>
    <groupId>io.codearte.accurest</groupId>
    <artifactId>accurest-maven-plugin</artifactId>
    <extensions>true</extensions>
</plugin>

instead of

<plugin>
    <groupId>io.codearte.accurest</groupId>
    <artifactId>accurest-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>convert</goal>
                <goal>generateStubs</goal>
                <goal>generateTests</goal>
            </goals>
        </execution>
    </executions>
</plugin>

I can achieve this with components.xml like below, but this requires some ugly hacks (specifing not existing phase - ugly-fix) and I'm not sure, if this solution is working in all cases.

<component-set>
    <components>
        <component>
            <role>org.apache.maven.lifecycle.Lifecycle</role>
            <implementation>org.apache.maven.lifecycle.Lifecycle</implementation>
            <role-hint>accurest</role-hint>
            <configuration>
                <id>accurest</id>
                <phases>
                    <phase>ugly-fix</phase> // plugin fail without this
                </phases>
                <default-phases>
                    <process-test-resources>
                        io.codearte.accurest:accurest-maven-plugin:${project.version}:convert
                    </process-test-resources>
                    <generate-test-sources>
                        io.codearte.accurest:accurest-maven-plugin:${project.version}:generateTests
                    </generate-test-sources>
                    <package>
                        io.codearte.accurest:accurest-maven-plugin:${project.version}:generateStubs
                    </package>
                </default-phases>
            </configuration>
        </component>
    </components>
</component-set>

Is this correct? Is better way to do such configuration?

• Working components.xml.
• Sample project which is using this configuration: https://github.com/mariuszs/gs-rest-service-accurest

You can achieve that by replacing ugly-fix with correct goals in <phases> tag:

<component-set>
  <components>
    <component>
        <role>org.apache.maven.lifecycle.Lifecycle</role>
        <implementation>org.apache.maven.lifecycle.Lifecycle</implementation>
        <role-hint>accurest</role-hint>
        <configuration>
            <id>accurest</id>
            <phases>
                <process-test-resources>
                    io.codearte.accurest:accurest-maven-plugin:${project.version}:convert
                </process-test-resources>
                <generate-test-sources>
                    io.codearte.accurest:accurest-maven-plugin:${project.version}:generateTests
                </generate-test-sources>
                <package>
                    io.codearte.accurest:accurest-maven-plugin:${project.version}:generateStubs
                </package>
            </phases>
            <default-phases>
                <process-test-resources>
                    io.codearte.accurest:accurest-maven-plugin:${project.version}:convert
                </process-test-resources>
                <generate-test-sources>
                    io.codearte.accurest:accurest-maven-plugin:${project.version}:generateTests
                </generate-test-sources>
                <package>
                    io.codearte.accurest:accurest-maven-plugin:${project.version}:generateStubs
                </package>
            </default-phases>
        </configuration>
    </component>
