Hi,
i have the following code which should resolve an artifact given GAV etc.
so far so good...
/**
* The project currently being build.
*/
@Parameter( defaultValue = "${project}" )
private MavenProject mavenProject;
/**
* The current Maven session.
*/
@Parameter( defaultValue = "${session}" )
private MavenSession mavenSession;
@Component
private ArtifactHandler artifactHandler;
@Component
private RepositorySystem repository;
private ArtifactResolutionResult resolve( String groupId, String
artifactId, String version, String type )
throws InvalidVersionSpecificationException
{
VersionRange versionRange = VersionRange.createFromVersion(
version );
Artifact artifact =
new DefaultArtifact( groupId, artifactId, versionRange,
Artifact.SCOPE_COMPILE, type, null, artifactHandler );
ArtifactResolutionRequest request = new
ArtifactResolutionRequest();
request.setArtifact( artifact )
.setResolveRoot( true )
.setResolveTransitively( false )
.setServers( mavenSession.getRequest().getServers() )
.setMirrors( mavenSession.getRequest().getMirrors() )
.setProxies( mavenSession.getRequest().getProxies() )
.setLocalRepository( mavenSession.getLocalRepository() )
.setRemoteRepositories(
mavenSession.getRequest().getRemoteRepositories() );
return repository.resolve( request );
}
My intention was to get the information if of a given artifact newer
versions exist so i thought to use a version range in the above code
like this:
VersionRange versionRange = VersionRange.createFromVersionSpec( "[" +
version + ",)");
which fails...it results in checking with a filename on the filesystem
which contains the version range specifier but not does not solving the
version range...
[INFO] Downloading:
file:///Users/kama/.m2/repository/junit/junit/[3.8,)/junit-[3.8,)
The question is: How can i check if a newer version of a given artifact
exists?
I have found the implementations in versions-maven-plugin but they look
like an overkill for me for simply check if there are newer versions
available or not...There i need a VersionsHelper etc. etc....
May be someone has a better simpler idea?
Many thanks in advance.
Kind regards
