Class ResolveEngine
resolve(File)
and
resolve(URL)

or more complete one, like the resolve(ModuleDescriptor, ResolveOptions)
which allows to
provide options to the resolution engine.- See Also:

downloadArtifacts
public void downloadArtifacts(ResolveReport report, Filter<Artifact> artifactFilter, DownloadOptions options) -
download
Download an artifact to the cache. Not used internally, useful especially for IDE plugins needing to download artifact one by one (for source or javadoc artifact, for instance).Downloaded artifact file can be accessed using
ArtifactDownloadReport.getLocalFile()
.It is possible to track the progression of the download using classical ivy progress monitoring feature (see addTransferListener).
- Parameters:
artifact
- the artifact to downloadoptions
- DownloadOptions- Returns:
- a report concerning the download
- See Also:
-
locate
Locates an artifact in dependency resolvers, and return its location if it can be located and actually exists, or an unknownArtifactOrigin
in other cases.- Parameters:
artifact
- the artifact to locate.- Returns:
- the artifact location, should be tested with
ArtifactOrigin.isUnknown(ArtifactOrigin)
to check if the artifact has actually been located.
-
download
Materialize an artifact already located.Not used internally, useful especially for IDE plugins needing to download artifact one by one (for source or javadoc artifact, for instance).
Materialized artifact file can be accessed using
ArtifactDownloadReport.getLocalFile()
.It is possible to track the progression of the download using classical ivy progress monitoring feature (see addTransferListener).
- Parameters:
origin
- the artifact origin to materializeoptions
- DownloadOptions- Returns:
- a report concerning the download
- See Also:
-
getDependencies
public IvyNode[] getDependencies(URL ivySource, ResolveOptions options) throws ParseException, IOException Resolve the dependencies of a module without downloading corresponding artifacts. The module to resolve is given by its ivy file URL. This method requires appropriate configuration of the ivy instance, especially resolvers.- Parameters:
ivySource
- url of the ivy file to use for dependency resolvingoptions
- ditto- Returns:
- an array of the resolved dependencies
- Throws:
ParseException
- if a parsing problem occurred in the ivy fileIOException
- if an IO problem was raised during ivy file parsing
-
getDependencies
Resolve the dependencies of a module without downloading corresponding artifacts. The module to resolve is given by its module descriptor. This method requires appropriate configuration of the ivy instance, especially resolvers.The
IvyNode
s are ordered from the most dependent to the less dependent, so that an IvyNode is always found in the list after all IvyNode depending directly on it.- Parameters:
md
- the descriptor of the module for which we want to get dependencies - must not be nulloptions
- the resolve options to use to resolve the dependenciesreport
- a resolve report to fill during resolution - may be null- Returns:
- an array of the resolved Dependencies

doFetchDependencies
-
isDependenciesFetched
Returns true if we've already fetched the dependencies for this node and configuration- Parameters:
node
- node to checkconf
- configuration to check- Returns:

resolveConflict

resolveConflict
private boolean resolveConflict(VisitNode node, VisitNode ancestor, String conf, Collection<IvyNode> toevict) Resolves conflict for the given node in the given ancestor. This method do conflict resolution in ancestor parents recursively, unless not necessary.- Parameters:
node
- the node for which conflict resolution should be doneancestor
- the ancestor in which the conflict resolution should be doneconf
- Stringtoevict
- a collection of IvyNode to evict (as computed by conflict resolution in descendants of ancestor)- Returns:
- true if conflict resolution has been done, false it can't be done yet
-
resolveConflicts
private Collection<IvyNode> resolveConflicts(VisitNode node, VisitNode ancestor, Collection<IvyNode> conflicts, ConflictManager conflictManager) -
computeConflicts
private Collection<IvyNode> computeConflicts(VisitNode node, VisitNode ancestor, String conf, Collection<IvyNode> toevict, Collection<IvyNode> selectedNodes) Compute possible conflicts for a node, in the context of an ancestor (a node which has a dependency - direct or indirect - on the node for which conflicts should be computed.- Parameters:
node
- the node for which conflicts should be computedancestor
- the ancestor in which conflicts should be computedconf
- the configuration of the node in which conflicts should be computedtoevict
- a collection of nodes which have been evicted during conflict resolution at lower level. It may be empty if no conflict resolution has occurred for this node yet, or if no node has been evicted.selectedNodes
- a collection of nodes selected during previous conflict resolution for the given node and ancestor. This collection is updated by this call, removing nodes which should be evicted.- Returns:
- a collection of IvyNode which may be in conflict with the given node in the given ancestor. This collection always contain at least the given node.

mediate
Mediates the given dependency descriptor according to given options.The mediated dependency descriptor must return the actually requested module revision id when the method
DependencyDescriptor.getDependencyRevisionId()
is called.- Parameters:
dd
- the dependency descriptor for which the requested module revision id should be returnedoptions
- the resolve options to use- Returns:
- the mediated
