DependencyGraphBuilder

public DependencyGraphBuilder()

DependencyGraphBuilder

public DependencyGraphBuilder(Iterable<String> mavenRepositoryUrls)

Parameters:

mavenRepositoryUrls - Maven repository URLs to search for dependencies

IllegalArgumentException - if a URL is malformed or does not have an allowed scheme

Method Detail

detectOsProperties

public static com.google.common.collect.ImmutableMap<String,String> detectOsProperties()

getDirectDependencies

public List<org.eclipse.aether.artifact.Artifact> getDirectDependencies(org.eclipse.aether.artifact.Artifact artifact)
                                                                 throws org.eclipse.aether.RepositoryException

Returns the non-transitive compile time dependencies of an artifact.

Throws:

org.eclipse.aether.RepositoryException

getStaticLinkageCheckDependencyGraph

public DependencyGraphResult getStaticLinkageCheckDependencyGraph(List<org.eclipse.aether.artifact.Artifact> artifacts)
                                                           throws org.eclipse.aether.RepositoryException

Finds the full compile time, transitive dependency graph including duplicates, conflicting versions, and dependencies with 'provided' scope.

Parameters:

artifacts - Maven artifacts to retrieve their dependencies

Returns:

dependency graph representing the tree of Maven artifacts

Throws:

org.eclipse.aether.RepositoryException - when there is a problem resolving or collecting dependencies

getCompleteDependencies

public DependencyGraphResult getCompleteDependencies(org.eclipse.aether.artifact.Artifact artifact)
                                              throws org.eclipse.aether.RepositoryException

Finds the full compile time, transitive dependency graph including duplicates and conflicting versions.

Throws:

org.eclipse.aether.RepositoryException

getTransitiveDependencies

public DependencyGraphResult getTransitiveDependencies(org.eclipse.aether.artifact.Artifact artifact)
                                                throws org.eclipse.aether.RepositoryException

Finds the complete transitive dependency graph as seen by Maven. It does not include duplicates and conflicting versions. That is, this resolves conflicting versions by picking the first version seen. This is how Maven normally operates.

Throws:

org.eclipse.aether.RepositoryException
