Maven - Aether - Repositories from settings.xml
Hi,
i'm using Aether to get the available versions of an artifact so far so
good...but currently i have line in the code which i would like to solve in
a different way instead of hard coding it:
Artifact artifact = new DefaultArtifact(
"com.soebes.subversion.sapm", "sapm", null, "[0,)");
RemoteRepository repo = new RemoteRepository( "central", "default",
"http://repo1.maven.org/maven2/" );
VersionRangeRequest rangeRequest = new VersionRangeRequest();
rangeRequest.setArtifact( artifact );
rangeRequest.addRepository( repo );
VersionRangeResult rangeResult = system.resolveVersionRange(
session, rangeRequest );
List versions = rangeResult.getVersions();
The line i wan't to do different is the following:
RemoteRepository repo = new RemoteRepository( "central", "default",
"http://repo1.maven.org/maven2/" );
Isn't there a better solution to the information about the repositories from
the current settings.xml file or from the system configuration settings.xml
file.
Does exist an example how to load the settings.xml of the user and the
system configuration to create the above repository configuration?
Many thanks in advance
Kind regards

You do realize that metadata is cached and only re-retrieved from the
remote side according to the update policy?

Hi Benjamin,
first many thanks for your hints....
But now i working on a small test program (FindAvailableVersions from Aether
Demo) to check how Aether is working and how i have to use it...
I observed a little thing which i didn't understand...
If i run the example the first time i got the following exception:

Furthermore in the interface RepositorySystem the method
VersionRangeResult resolveVersionRange( RepositorySystemSession session,
VersionRangeRequest request )
throws VersionRangeResolutionException;
does not define this kind of Exception so i have no chance to catch such
kind of exception...
If i run the example the second time the exception does not appear a second
time....and not on all further runnings...
If i delete the local repository and start it again i got the above
exception...
So may be someone has a good hint about that...
Many thanks in advance

http://maven.apache.org/ref/3.0.3/maven-settings-builder/apidocs/org/apache/maven/settings/building/SettingsBuilder.html
and related components from the maven-settings-builder should do.
Depending on how fancy you need to get, you might also want to use
http://maven.apache.org/ref/3.0.3/maven-model-builder/apidocs/org/apache/maven/model/profile/ProfileSelector.html
