Detailed Description

Resolver of dependencies for one artifact.

#143 This class should be @Immutable, but RemoteRepository is not immutable. Let's create a new class to encapsulate all necessary properties from RemoteRepository.

You need the following dependencies to have in classpath in order to to work with this class:

org.sonatype.aether:aether-api:1.13.1
org.apache.maven:maven-core:3.0.3

Constructor & Destructor Documentation

Aether()

grammarscope.generator.codedeps.Aether.Aether	(	final RemoteRepository[]	remotes,
		final File	repo
	)

Public ctor, requires information about all remote repos and one local.

Parameters

remotes	Remote repositories
repo	Local repository location (directory path)

Member Function Documentation

fetch()

List<Artifact> grammarscope.generator.codedeps.Aether.fetch ( final RepositorySystemSession  session, final DependencyRequest  dreq  ) throws DependencyResolutionException

private

Fetch dependencies. #51 This catch of NPE is a temporary measure. I don't know why Aether throws NPE in case of unresolvable artifact. This is the best I can do at the moment in order to protect clients of the class.

Parameters

session	The session
dreq	Dependency request

Returns

The list of dependencies

Exceptions

DependencyResolutionException

If can't fetch it

reps()

static Collection<String> grammarscope.generator.codedeps.Aether.reps ( final Collection< RemoteRepository >  repos )

staticprivate

Convert a list of repositories into a list of strings.

Parameters

repos

The list of them

Returns

The list of texts

request()

CollectRequest grammarscope.generator.codedeps.Aether.request ( final Dependency  root )

private

Create collect request.

Parameters

root	The root to start with

Returns

The request

resolve() [1/2]

List<Artifact> grammarscope.generator.codedeps.Aether.resolve	(	final Artifact	root,
		final String	scope
	)		throws DependencyResolutionException

List of transitive deps of the artifact. #51 This "filter IF NOT NULL" validation is a workaround, since I don't know what the actual problem is. Looks like sometimes (for some unknown reason) #classpathFilter() returns NULL. When exactly this may happen I have no idea. That's why this workaround. Sometime later we should do a proper testing and reproduce this defect in a test.

Parameters

root	The artifact to work with
scope	The scope to work with ("runtime", "test", etc.)

Returns

The list of dependencies

Exceptions

DependencyResolutionException

If can't fetch it

resolve() [2/2]

List<Artifact> grammarscope.generator.codedeps.Aether.resolve	(	final Artifact	root,
		final String	scope,
		final DependencyFilter	filter
	)		throws DependencyResolutionException

List of transitive deps of the artifact.

Parameters

root	The artifact to work with
scope	The scope to work with ("runtime", "test", etc.)
filter	The dependency filter to work with

Returns

The list of dependencies

Exceptions

DependencyResolutionException

If can't fetch it

session()

RepositorySystemSession grammarscope.generator.codedeps.Aether.session ( )

private

Create RepositorySystemSession.

Returns

The session

Member Data Documentation

remotes

final transient RemoteRepository [] grammarscope.generator.codedeps.Aether.remotes

private

system

final transient RepositorySystem grammarscope.generator.codedeps.Aether.system = RepositorySystemBuilder.build()
