We need to turn this list of phases into a set of plugin objects that have an XML representation like the following:

          <goal>process</goal>
        </goals>
      </execution>
    </executions>

        assertEquals("", projectId, "Should return empty string when all models are null");
    }

    private Model createMockModel(String groupId, String artifactId, String version) {
        return Model.newBuilder()
                .groupId(groupId)
                .artifactId(artifactId)
                .version(version)
                .packaging("jar")
                .build();
    }

        String classifier = artifact.getClassifier();

    simple request and response logging. It may be configured to log headers and
    bodies for debugging. It requires this Maven dependency:

     ```xml
     <dependency>
       <groupId>com.squareup.okhttp</groupId>
       <artifactId>logging-interceptor</artifactId>
       <version>2.6.0</version>
     </dependency>
     ```

    Configure basic logging like this:

    ```java

     */
    String getGroupId();

    /**
     * Sets the group id of the plugin.
     *
     * @param groupId The group id of the plugin.
     * @return This request, never {@code null}.
     */
    PluginVersionRequest setGroupId(String groupId);

    /**
     * Gets the artifact id of the plugin.
     *
     * @return The artifact id of the plugin.
     */
    String getArtifactId();

  <modelVersion>4.0.0</modelVersion>
