Hi,

our problem looks like a Maven configuration issue but I'm asking it in this forum nonetheless since I couldn't find any documentation from Drools on how
to correctly setup maven in order to work with Drools.

First of all, here's how we create our kieContainer:

KieServices kieServices = KieServices.Factory.get();

ReleaseId releaseId = kieServices.newReleaseId("foo.bar", "artifact-name", "1.0.0-SNAPSHOT");

kContainer = kieServices.newKieContainer(releaseId);

This is the settings.xml that should be used by our application server (wildfly system property kie.maven.settings.custom set to "/home/myuser/.m2/settings.xml"):

<?xml version="1.0"?>
<settings>
  <localRepository>/opt/foo/mavenrepo</localRepository>
  <profiles>
    <profile>
      <id>nexus</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <repositories>
        <repository>
          <id>nexus</id>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
          </snapshots>
        </repository>
      </repositories>
    </profile>
  </profiles>
</settings>


When we call our Rules Service it pauses for like 20 seconds and then retrieves the rules artifact from "ournexusserver" and stores it in the local maven repository.
However, in the reslover-status.properties of the rules artifact we see the following:

#NOTE: This is an internal implementation file, its format can be changed without prior notice.
#Thu Jan 29 15:41:00 CET 2015
maven-metadata-local.xml.lastUpdated=1422534634178
maven-metadata-central.xml.error=Could not transfer metadata foo.bar\:artifact-name\:1.0.0-SNAPSHOT/maven-metadata.xml from/to central (http\://repo1.maven.org/maven2/)\: Connection refused
maven-metadata-central.xml/default-http\://repo1.maven.org/maven2/.lastUpdated=1422534634327
maven-metadata-nexus.xml.lastUpdated=1422542460018
maven-metadata-local.xml.error=


So it seems to try to connect to repo1.maven.org first and look for our artifact there which, of course, doesn't make sense.

You might propose to include a <mirrors> section in the settings.xml like the following:

<mirrors>
<mirror>
<id>ournexus</id>
<mirrorOf>*</mirrorOf>
</mirror>
</mirrors>

However, if we do this then the whole artifact retrieval process fails with the following exception:

11:32:24,981 WARN  [8e38ebe8-ae10-4539-9ca5-4dbb6364fa07] [MavenRepository] Unable to resolve artifact: foo.bar:artifact-name:pom:1.0.0-SNAPSHOT: org.sonatype.aether.resolution.ArtifactResolutionException: Could not transfer artifact foo.bar:artifact-name:pom:1.0.0-SNAPSHOT from/to ournexus (http://ournexusserver:8081/nexus/content/groups/public): No connector available to access repository ournexus (http://ournexusserver:8081/nexus/content/groups/public) of type  using the available factories FileRepositoryConnectorFactory, WagonRepositoryConnectorFactory

So the question is: How do we need to configure Maven/Drools so that it talks to our nexus server directly and doesn't try to get to repo1.maven.org?

Ok, here's the answer.
I looked through the kie-ce sourceode and found the root cause in the class Ather.java.

The following method adds repo1.maven.org to the list of repositories that are searched:

 private RemoteRepository newCentralRepository() {
        return new RemoteRepository( "central", "default", "http://repo1.maven.org/maven2/" );
    }

This method is called here:

 private Collection<RemoteRepository> initRepositories(MavenProject mavenProject) {
        Collection<RemoteRepository> reps = new HashSet<RemoteRepository>();
        //reps.add(newCentralRepository());
        if (mavenProject != null) {
            reps.addAll(mavenProject.getRemoteProjectRepositories());
        }

        RemoteRepository localRepo = newLocalRepository();
        if (localRepo != null) {
            reps.add(localRepo);
            localRepository = localRepo;
        } else {
            localRepoDir = IoUtils.getTmpDirectory().getAbsolutePath();
        }
        return reps;
    }

As you can see I just commented out the line that adds the central repo and now we don't have to wait 15s for our kieContainer to load the rules from our internal Nexus repository while trying to reach repo1.maven.org without success.

Not sure if any of the drools developers is reading this but it might be interesting to know if there is another way to tell kie-ci not to connect to repo1.maven.org.

Hi Philipp,

thanks a lot for having reported this.
I'll give a look asap and eventually provide a fix.

Cheers,
Mario

Hi again Philipp,

I tried to give a look at this but at the moment I don't agree with your analysis nor I've been able to reproduce the problem.

In more details what you wrote about what happens in the Aether class is correct but it's only part of the story. The maven repositories used to perform a given request are collected in the method MavenRepository.initRemoteRepositoriesForRequest and in particular here it iterates through the repos created by the Aether class https://github.com/droolsjbpm/drools/blob/6.1.x/kie-ci/src/main/java/org/kie/scanner/MavenRepository.java#L99 (I'm pointing to the 6.1.x branch because it seems you're using the 6.1.0 release but please advice if you're on a different version).

As you can see there, each repository (including the central maven one) before being added to the set of repositories to be used in a request is checked using the resolveMirroredRepo method that in turn uses the isMirror that always returns true if you use the * wildcard as you did: https://github.com/droolsjbpm/drools/blob/6.1.x/kie-ci/src/main/java/org/kie/scanner/MavenRepository.java#L117

Please advice if you think it is happening something different from what I described and possibly provide a reproducer for you problem.

Thanks,
Mario

Hi Mario,

I must admit that it is a bit difficult for me to provide a small example application to demonstrate the issue since we are working on a bigger Java EE 7 application that uses Drools in its Rules Service.
We currently have 2 scenarios that do not work as expected:
1. If we use a <mirror> section in the settings.xml that is used by our application (by setting the kie.maven.settings.custom property on the application server) we get the following Exception:
WARN  MavenRepository - Unable to resolve artifact: com.swisscom.contactcenter.sccp.dice:dice-rules-personalization:1.0.0-SNAPSHOT
org.sonatype.aether.resolution.ArtifactResolutionException: Could not transfer artifact foo.bar:rules-artifact:jar:1.0.0-SNAPSHOT from/to ourhost-nexus (http://ourhost:8081/nexus/content/groups/public): No connector available to access repository sdsccpivr11-nexus (http://ourhost:8081/nexus/content/groups/public) of type  using the available factories FileRepositoryConnectorFactory, WagonRepositoryConnectorFactory

2. If we remove the <mirrors> section from the settings.xml the rules are retrieved from the configured nexus in our LAN but it takes around 15-17 seconds until this is finally done. In the meantime it seems a connection attempt is made to repo1.maven.org although this should be disabled in our settings.xml. There is no log output so we don't really know what's going on in this pause. Here is our settings.xml that is used during runtime:
<?xml version="1.0"?>
<settings>
  <localRepository>/opt/sccp/mavenrepo</localRepository>
  <profiles>
    <profile>
      <id>nexus-profile</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <repositories>
        <repository>
          <id>nexus</id>
          <releases>

          </snapshots>
        </repository>
        <repository>
          <id>central</id>

          <releases>
            <enabled>false</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
      </repositories>
    </profile>
  </profiles>
</settings>


I'm pretty sure this is a maven issue and not a rules issue but after searching the web for weeks I couldn't find any hint what the problem might be.
Also, inside the rules JAR there is the pom.xml from our source project and I'm not sure if something should be changed there.

Also, we are using SNAPSHOT versions for our rules artifacts so maybe this is a problem?

I think I'll have to try to create a small sample project (on "Rules Service" project and one "rules" project) to reproduce the issue.

Hi Philipp,

I'm sorry but I still cannot reproduce this issue on my side.
Did you check if you have the same problem also with the 6.2.0.Final? If so it would be really helpful if you could send me a reproducer.

Thanks a lot,
Mario

Hi Mario,

I have tried to create a little Reproducer-Application that uses the Rules in the same way that we do in our JEE Application.
I have M2_HOME on my local PC set to a path with the following settings.xml used for the test:
<settings>
<servers>
<server>
<id>releases</id>
<username>deployment</username>
<password>deployment123</password>
</server>
<server>
<id>snapshots</id>
<username>deployment</username>
<password>deployment123</password>
</server>
</servers>
<mirrors>
<mirror>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
</mirror>
</mirrors>
<localRepository>Z:\mavenrepo\repository\</localRepository>

Server "nexus" is running a Sonatype OSS Nexus and contains the artifacts for drools-model and rules-artifact.

Hi, in the hope it might be helpful.

I was in the same need, resolving rules kjar artifacts only to an internal nexus repo, without going to maven central repo.
I have the following settings file, and I set -Dkie.maven.settings.custom=C:/Users/mmortari/.m2/kie-settings.xml while starting the WildFly server, my Java EE application does only attempt to resolve the kjar artifacts only to internal repo.

Please notice: with 6.1.0.Final, you need to ensure the mirror definition has the layout=default, otherwise you will get the ArtifactResolutionException: ... No connector available to access repository...of type  using the available factories FileRepositoryConnectorFactory, WagonRepositoryConnectorFactory
With 6.2.0.Final instead, I didn't notice the need to ensure the mirror definition layout element, I left it out from the kie-settings.xml.

So in conclusion, the below should be the minimal kie-settings.xml required, if you pass it as kie.maven.settings.custom system properties.

At least it works for me with 6.1.0.Final.

<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Plus,
I would like to add this "workaround" about the need to specify the mirror's definition to have the layout=default element is, as far as I understand, NOT a Drools bug, but a Maven library bug.

I think this is the culprit, because kie-ci of Drools 6.1.0.Final uses org.apache.maven / maven-settings version 3.0.5 while kie-ci of Drools 6.2.0.Final uses org.apache.maven / maven-settings version 3.2.2

and finally the reason is that ArtifactResolutionException: ... No connector available to access repository...of type  using the available factories FileRepositoryConnectorFactory, WagonRepositoryConnectorFactory exception which I get on 6.1.0.Final is because mirror would have wrong type in the sonatype's library in turn, hence not be able to use the WagonRepositoryConnector.

But anyway, at least in my case I got the settings to work both for 610Final and 620Final exactly the way I needed, same as your original need, resolve kjar rule only from internal nexus maven repository =)

Hi Matteo,

thank your very much for your response. This indeed solves the issue we had with 6.1.0.Final not being able to use <mirror> in our Maven settings.
I was sure that this is a Maven problem pretty much from the beginning.

Cheers
Philipp

Ciao, this is to follow-up on my answer of Mar 26th [1]

I discovered that the kie maven settings I suggested originally, indeed solved the original requirement to avoid contact maven central (repo1.maven.org etc.) and just reference internal/custom nexus repo to resolve for the rule artifact package.

However, the release/snapshot update policy which I later set for the internal/custom nexus repo was not correctly taken into account by the Eclipse's Aether library. In summary, the release/snapshot version was refreshed only daily because the maven-metadata was refreshed only daily, regardless I wanted it to be refreshed always.

I found the following kie maven settings is actually better because:
  • it avoids contact maven central (repo1.maven.org etc.) and just reference internal/custom nexus repo to resolve for the rule artifact
  • it take into account the specified updatePolicy=always for the release/snapshot of the internal/custom nexus repo
Below the "improved" kie maven settings I'm currently using and which I pass as kie.maven.settings.custom system properties. Please notice is explicit non-colliding IDs and mirrorOf explicitly excludes the internal/custom nexus repo from the mirroring. Please notice the updatePolicy=always for the internal/custom nexus repo.

I hope this helps, I've spent quite some time to figure this out =) so I hope this avoid somebody's else pain with the Eclipse's Aether library LOL

  <layout>default</layout> <!-- this line layout=default is very important if using 6.1.0.Final (depends on org.apache.maven / maven-settings version 3.0.5). Otherwise less important as kie-ci of Drools 6.2.0.Final uses org.apache.maven / maven-settings version 3.2.2 and the layout=default is indeed the default behavior correctly set. Potential culprit: http://grepcode.com/file_/repo1.maven.org/maven2/org.apache.maven/maven-settings/3.2.2/org/apache/maven/settings/Mirror.java/?v=diff&id2=3.0.5 This is I believe the maven-settings bug : http://jira.codehaus.org/browse/MNG-5016 -->
