Kie-Server exception - Could not transfer artifact from/to central (http://repo1.maven.org/maven2/)

[Maniganda Prakash]

Following exception is thrown in 'Kie-Server v6.2.0' while creating a container in 'Kie Workbench v 6.2.0':

01:15:22,501 WARN  [org.kie.scanner.MavenRepository] Unable to resolve artifact: first.second:third:1.0: org.eclipse.aether.resolution.ArtifactResolutionException: Could not transfer artifact first.second:third:jar:1.0 from/to central (http://repo1.maven.org/maven2/): repo1.maven.org
        at org.eclipse.aether.internal.impl.DefaultArtifactResolver.resolve(DefaultArtifactResolver.java:444) [aether-impl-1.0.0.v20140518.jar:]
        at org.eclipse.aether.internal.impl.DefaultArtifactResolver.resolveArtifacts(DefaultArtifactResolver.java:246) [aether-impl-1.0.0.v20140518.jar:]

As shown in the screen shot,
 - 'Kie-workbench v6.2.0' and 'Kie-Server v6.2.0' are installed in two different servers.
 - This property is set in both 'workbench' and 'execution server' <property name="org.guvnor.m2repo.dir" value="/drools/mvn"/>
 - In Kie-workbench, when I build and deploy, artifacts are stored in the directory '/drools/mvn' as expected in the first server
 - Manually I copied '/drools/mvn' directory to the Server 2 (to Kie-Server)
 - Exception is thrown when I create a Kie-server container in the workbench with valid group and artifact id

Why does Kie-server go to 'repo1.maven.org' instead of looking at the directory '/drools/mvn' as I set the property?
Is there any other property I have to set so that Kie-server doesn't refer 'repo1.maven.org'?

Thanks,
Prakash

Property org.guvnor.m2repo.dir is used by the Workbench to determine where to store artifacts within it's "internal" M2 Repository; and AFAIK is not used by KIE Server.

KIE Server probably uses either the <repositories> configured in the deployed KJAR's pom.xml or those in the local settings.xml. Can you confirm neither are configured to use repo1.maven.org?

If both Kie-workbench and Kie-Server are deployed in the same server (server 1) then the Kie-Server correctly loads the artifact from '/drools/mvn' instead of referring to 'repo1.maven.org'.

How does Kie-server load the artifact from my '/drools/mvn' directory if deployed along with workbench in the same server? How can I make Kie-Server to refer to my '/drools/mvn' directory even if workbench and Kie-server are deployed in different servers?

Thanks,
Prakash

To be honest, I don't know.. I'd be very surprised if it used the "org.guvnor.m2repo.dir" property.. Very surprised indeed.

I'd think kie-server would use whatever Maven configuration is available at runtime.. but I've BCC'ed a couple of colleagues who developed the kie-server for their opinion...

With kind regards,

Mike

   Michael is correct. Kie-server uses kie-ci to resolve repositories and download jars. Kie-ci uses default maven configuration files, including "settings.xml". So make sure you configure your remote maven repositories in there.
