Package org.apache.maven.api

Interface Project

All Known Implementing Classes:
DefaultProject
@Experimental public interface Project
Interface representing a Maven project which can be created using the ProjectBuilder service. Such objects are immutable and plugin that wish to modify such objects need to do so using the ProjectManager service.

Projects are created using the ProjectBuilder from a POM file (usually named pom.xml) on the file system. The getPomPath() will point to the POM file and the getBasedir() to the directory parent containing the POM file.

Since:
4.0.0

  • Method Details

    • getGroupId

      @Nonnull String getGroupId()
      Returns the project groupId.

    • getArtifactId

      @Nonnull String getArtifactId()
      Returns the project artifactId.

    • getVersion

      @Nonnull String getVersion()
      Returns the project version.

    • getPackaging

      @Nonnull Packaging getPackaging()
      Returns the project packaging.

      Note: unlike in legacy code, logical checks against string representing packaging (returned by this method) are NOT recommended (code like "pom".equals(project.getPackaging) must be avoided). Use method getArtifacts() to gain access to POM or build artifact.

      See Also:

    • getLanguage

      @Nonnull default Language getLanguage()
      Returns the project language. It is by default determined by getPackaging().
      See Also:

    • getPomArtifact

      @Nonnull default Artifact getPomArtifact()
      Returns the project POM artifact, which is the artifact of the POM of this project. Every project have a POM artifact, even if the existence of backing POM file is NOT a requirement (i.e. for some transient projects).
      See Also:

    • getMainArtifact

      @Nonnull default Optional<Artifact> getMainArtifact()
      Returns the project main artifact, which is the artifact produced by this project build, if applicable. This artifact MAY be absent if the project is actually not producing any main artifact (i.e. "pom" packaging).
      See Also:

    • getArtifacts

      @Nonnull List<Artifact> getArtifacts()
      Returns the project artifacts as immutable list. Elements are the project POM artifact and the artifact produced by this project build, if applicable. Hence, the returned list may have one or two elements (never less than 1, never more than 2), depending on project packaging.

      The list's first element is ALWAYS the project POM artifact. Presence of second element in the list depends solely on the project packaging.

      See Also:

    • getModel

      @Nonnull Model getModel()
      Returns the project model.

    • getBuild

      @Nonnull default Build getBuild()
      Shorthand method.

    • getPomPath

      @Nonnull Path getPomPath()
      Returns the path to the pom file for this project. A project is usually read from a file named pom.xml, which contains the model in an XML form. When a custom org.apache.maven.api.spi.ModelParser is used, the path may point to a non XML file.

      The POM path is also used to define the base directory of the project.

      Returns:
      the path of the pom
      See Also:

    • getBasedir

      @Nonnull Path getBasedir()
      Returns the project base directory, i.e. the directory containing the project. A project is usually read from the file system and this will point to the directory containing the POM file.
      Returns:
      the path of the directory containing the project

    • getDependencies

      @Nonnull List<DependencyCoordinate> getDependencies()
      Returns the project direct dependencies (directly specified or inherited).

    • getManagedDependencies

      @Nonnull List<DependencyCoordinate> getManagedDependencies()
      Returns the project managed dependencies (directly specified or inherited).

    • getId

      @Nonnull default String getId()
      Returns the project ID, usable as key.

    • isTopProject

      boolean isTopProject()
      Returns a boolean indicating if the project is the top level project for this reactor build. The top level project may be different from the rootDirectory, especially if a subtree of the project is being built, either because Maven has been launched in a subdirectory or using a -f option.
      Returns:
      true if the project is the top level project for this build

    • isRootProject

      boolean isRootProject()
      Returns a boolean indicating if the project is a root project, meaning that the getRootDirectory() and getBasedir() points to the same directory, and that either Model.isRoot() is true or that basedir contains a .mvn child directory.
      Returns:
      true if the project is the root project
      See Also:

    • getRootDirectory

      @Nonnull Path getRootDirectory()
      Gets the root directory of the project, which is the parent directory containing the .mvn directory or flagged with root="true".
      Throws:
      IllegalStateException - if the root directory could not be found
      See Also:

    • getParent

      @Nonnull Optional<Project> getParent()
      Returns project parent project, if any.
