Method Detail

• resolveVersionRange

  VersionRangeResult resolveVersionRange(RepositorySystemSession session,
                                       VersionRangeRequest request)
                                         throws VersionRangeResolutionException

  Expands a version range to a list of matching versions, in ascending order. For example, resolves "[3.8,4.0)" to "3.8", "3.8.1", "3.8.2". Note that the returned list of versions is only dependent on the configured repositories and their contents, the list is not processed by the session's version filter.

  The supplied request may also refer to a single concrete version rather than a version range. In this case though, the result contains simply the (parsed) input version, regardless of the repositories and their contents.

  Parameters:

  session - The repository session, must not be null.

  request - The version range request, must not be null.

  Returns:

  The version range result, never null.

  Throws:

  VersionRangeResolutionException - If the requested range could not be parsed. Note that an empty range does not raise an exception.

                               throws VersionResolutionException

  Resolves an artifact's meta version (if any) to a concrete version. For example, resolves "1.0-SNAPSHOT" to "1.0-20090208.132618-23".

  Parameters:

  session - The repository session, must not be null.

  request - The version request, must not be null.

  Gets information about an artifact like its direct dependencies and potential relocations.

  Parameters:

  session - The repository session, must not be null.

  request - The descriptor request, must not be null.

  Returns:

  The descriptor result, never null.

  Throws:

  ArtifactDescriptorException - If the artifact descriptor could not be read.

• collectDependencies

  CollectResult collectDependencies(RepositorySystemSession session,
                                  CollectRequest request)
                                    throws DependencyCollectionException

  Collects the transitive dependencies of an artifact and builds a dependency graph. Note that this operation is only concerned about determining the coordinates of the transitive dependencies. To also resolve the actual artifact files, use resolveDependencies(RepositorySystemSession, DependencyRequest).

  Parameters:

  session - The repository session, must not be null.

  request - The collection request, must not be null.

  Returns:

  The collection result, never null.

  Throws:

  DependencyCollectionException - If the dependency tree could not be built.

• resolveDependencies

  DependencyResult resolveDependencies(RepositorySystemSession session,
                                     DependencyRequest request)
                                       throws DependencyResolutionException

  Collects and resolves the transitive dependencies of an artifact. This operation is essentially a combination of collectDependencies(RepositorySystemSession, CollectRequest) and resolveArtifacts(RepositorySystemSession, Collection).

  Parameters:

  session - The repository session, must not be null.

  request - The dependency request, must not be null.

  Returns:

  The dependency result, never null.

  Throws:

  DependencyResolutionException - If the dependency tree could not be built or any dependency artifact could not be resolved.

• resolveArtifact

  ArtifactResult resolveArtifact(RepositorySystemSession session,
                               ArtifactRequest request)
                                 throws ArtifactResolutionException

  Resolves the path for an artifact. The artifact will be downloaded to the local repository if necessary. An artifact that is already resolved will be skipped and is not re-resolved. In general, callers must not assume any relationship between an artifact's resolved filename and its coordinates. Note that this method assumes that any relocations have already been processed.

  Parameters:

  session - The repository session, must not be null.

  request - The resolution request, must not be null.

  Returns:

  The resolution result, never null.

  Throws:

  ArtifactResolutionException - If the artifact could not be resolved.

                                        throws ArtifactResolutionException

  Resolves the paths for a collection of artifacts. Artifacts will be downloaded to the local repository if necessary. Artifacts that are already resolved will be skipped and are not re-resolved. In general, callers must not assume any relationship between an artifact's filename and its coordinates. Note that this method assumes that any relocations have already been processed.

  Parameters:

  session - The repository session, must not be null.

  requests - The resolution requests, must not be null.

  Returns:

  The resolution results (in request order), never null.

  Throws:

  ArtifactResolutionException - If any artifact could not be resolved.

  Artifact.getFile(), newResolutionRepositories(RepositorySystemSession, List)

• resolveMetadata

  List<MetadataResult> resolveMetadata(RepositorySystemSession session,
                                     Collection<? extends MetadataRequest> requests)

  Resolves the paths for a collection of metadata. Metadata will be downloaded to the local repository if necessary, e.g. because it hasn't been cached yet or the cache is deemed outdated.

  Parameters:

  session - The repository session, must not be null.

  requests - The resolution requests, must not be null.

  Returns:

  The resolution results (in request order), never null.

• newLocalRepositoryManager

  LocalRepositoryManager newLocalRepositoryManager(RepositorySystemSession session,
                                                 LocalRepository localRepository)

  Creates a new manager for the specified local repository. If the specified local repository has no type, the default local repository type of the system will be used. Note: It is expected that this method invocation is one of the last steps of setting up a new session, in particular any configuration properties should have been set already.

  Parameters:

  session - The repository system session from which to configure the manager, must not be null.

  localRepository - The local repository to create a manager for, must not be null.

  Returns:

  The local repository manager, never null.

  Throws:

  IllegalArgumentException - If the specified repository type is not recognized or no base directory is given.

• newSyncContext

  SyncContext newSyncContext(RepositorySystemSession session,
                           boolean shared)

  Creates a new synchronization context.

  Parameters:

  session - The repository session during which the context will be used, must not be null.

  shared - A flag indicating whether access to the artifacts/metadata associated with the new context can be shared among concurrent readers or whether access needs to be exclusive to the calling thread.

  Returns:

  The synchronization context, never null.

• newResolutionRepositories

  List<RemoteRepository> newResolutionRepositories(RepositorySystemSession session,
                                                 List<RemoteRepository> repositories)

  Forms remote repositories suitable for artifact resolution by applying the session's authentication selector and similar network configuration to the given repository prototypes. As noted for RepositorySystemSession.getAuthenticationSelector() etc. the remote repositories passed to e.g. resolveArtifact() are used as is and expected to already carry any required authentication or proxy configuration. This method can be used to apply the authentication/proxy configuration from a session to a bare repository definition to obtain the complete repository definition for use in the resolution request.

  Parameters:

  session - The repository system session from which to configure the repositories, must not be null.

  repositories - The repository prototypes from which to derive the resolution repositories, must not be null or contain null elements.

  Returns:

  The resolution repositories, never null. Note that there is generally no 1:1 relationship of the obtained repositories to the original inputs due to mirror selection potentially aggregating multiple repositories.

  newDeploymentRepository(RepositorySystemSession, RemoteRepository)

• newDeploymentRepository

  RemoteRepository newDeploymentRepository(RepositorySystemSession session,
                                         RemoteRepository repository)

  Forms a remote repository suitable for artifact deployment by applying the session's authentication selector and similar network configuration to the given repository prototype. As noted for RepositorySystemSession.getAuthenticationSelector() etc. the remote repository passed to deploy() is used as is and expected to already carry any required authentication or proxy configuration. This method can be used to apply the authentication/proxy configuration from a session to a bare repository definition to obtain the complete repository definition for use in the deploy request.

  Parameters:

  session - The repository system session from which to configure the repository, must not be null.

  repository - The repository prototype from which to derive the deployment repository, must not be null.

  Returns:

  The deployment repository, never null.
