Class ArtifactCache

java.lang.Object

org.wildfly.prospero.galleon.ArtifactCache

public class ArtifactCache
extends Object

Manages artifact cache located in installationDir/CACHE_FOLDER. Cached artifacts are listed in CACHE_FOLDER/CACHE_FILENAME. Each artifact is identified by its GAV and specifies an SHA-1 hash of the file and a relative path were the artifact can be found within installationDir. If the artifact cannot be found within Galleon-provisioned installationDir, the artifact can be added to the CACHE_FOLDER. The cache is rebuild during update and only current artifacts are stored.

Method Details

getInstance

public static ArtifactCache getInstance(Path installationDir)
                                 throws IOException

returns artifact cache located at installationDir/{code CACHE_FOLDER}

Parameters:

installationDir -

Returns:

Throws:

IOException - if the cache descriptor is corrupt and cannot be read

cleanInstancesCache

public static void cleanInstancesCache()

getArtifact

public Optional<File> getArtifact(String groupId,
 String artifactId,
 String extension,
 String classifier,
 String version)

finds a file associated with the GAV in the local installationDir. The file is only matched if it's GAV is recorded in cache descriptor and the file has not been modified since the cache was created.

Parameters:

groupId -

artifactId -

extension -

classifier -

version -

Returns:

empty Optional if the file has not been matched, otherwise the matching File

record

public void record(org.wildfly.channel.MavenArtifact artifact,
 Path pathToArtifact)
            throws IOException

records file in the cache descriptor. The recorded path is relative to installationDir

Parameters:

artifact - - artifact to be recorded

pathToArtifact - - location in the installation where the artifact can be found

Throws:

IOException

cache

public void cache(org.wildfly.channel.MavenArtifact artifact)
           throws IOException

caches the artifact in CACHE_FOLDER. The cached artifact is then recorded in the cache list.

Parameters:

artifact -

Throws:

IOException

cache

public void cache(org.wildfly.prospero.metadata.ManifestVersionRecord manifestRecord,
 org.eclipse.aether.repository.LocalRepositoryManager localRepositoryManager)
           throws IOException

detects and caches the manifests from manifestRecord in CACHE_FOLDER. The version and content of the manifest is resolved using resolvedArtifacts. NOTE: only manifests identified by maven coordinates are cached.

Parameters:

manifestRecord - - record containing all manifest used in installation.

localRepositoryManager - - Maven manager for the local repository.

Throws:

IOException
