Inheritance in Maven

 In order the understand how inheritance works in Maven there are a few notions that you must be familiar with:

 * The maven super model

 * how parent poms are processed

 * the order in which elements in the POM are overridden

 * minimum element-set for a valid project pom


Maven super model

public class DefaultProjectDependencyGraph implements ProjectDependencyGraph {

    private final ProjectSorter sorter;

    private final List<MavenProject> allProjects;

    private final Map<MavenProject, Integer> order;

    private final Map<String, MavenProject> projects;

    /**
     * Creates a new project dependency graph based on the specified projects.
     *

     * This is required for tracking and analytics purposes.
     */
    @Required
    public String queryId;

    /**
     * Order or ranking position of the document in search results.
     * This optional field helps track which result position was clicked.
     */
    public Integer order;

    // for error page

    /**
     * Query string parameter for error page fallback.

   on plugin goals execution order:

   * <<in a given phase, goals order is not expected to be guaranteed nor finely tuned>>:
     it is just a consequence of the order obtained during {{{../maven-model-builder/}effective model building}},
     which combines profile activation+injection and inheritance assembly from parents,

  /** Ciphers in order we observed directly on the socket. */
  private lateinit var handshakeEnabledCipherSuites: List<String>

  /** Ciphers in order we observed on sslSocketFactory defaults. */
  private lateinit var defaultEnabledCipherSuites: List<String>

  /** Ciphers in order we observed on sslSocketFactory supported. */

  /*
   * While the current implementation returns `this`, that's not something we mean to guarantee.
   * Callers of TestContainerGenerator.order need to be prepared for implementations to return a new
   * collection.
