Trying to proxy a custom repository using nexus. no luck so far.

Chris Bedford



Hi -


I am trying to configure nexus to proxy the repo http://clojars.org/repo/
I added this repository as a proxy repository with the above URL. 
I then added this proxy repository to the public  group.
When I did 'Browse Remote' and 'Browse Index' everything looked good. 

But when I modify a very simple project to include 
a dependency on a .jar that resides in the aforementioned repo, I get this error: 


[ERROR] Failed to execute goal on project findFiles: Could not resolve dependencies for project com.lackey:findFiles:jar:1.0-SNAPSHOT: Failure to find org.clojars.brenden:storm-kafka-0.8-plus:jar:0.1.3-SNAPSHOT in http://dmip.buildserver.fairisaac.com:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]


I got this error as I was experimenting with 
a very simple project which I created like this:

mvn archetype:generate -DarchetypeGroupId=org.codehaus.groovy.maven.archetypes -DarchetypeArtifactId=gmaven-archetype-basic -DgroupId=com.lackey -DartifactId=findFiles -Dpackage=com.lackey

To create my ~/.m2/settings.xml I followed these directions: 

Then I wiped out my ~/.m2/repository  and I verified that everything was downloading from my nexus server.   Good start.



Next I added a dependency on an artifact that resides in the clojars repo.

I modified my pom to include this :  

          <dependency>
                <groupId>org.clojars.brenden</groupId>
                <artifactId>storm-kafka-0.8-plus</artifactId>
                <version>0.1.3-SNAPSHOT</version>
            </dependency>



Then I got the above error.

After I got the error I tried adding the config shown below (starting at NEW
addition)  to my settings XML file 

        
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://central</url>
          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </repository>

<!--   NEW addition.. did not work :^(    -->
        <repository>
            <id>clojars</id>
            <releases><enabled>true</enabled></releases>
            <snapshots><enabled>true</enabled></snapshots>
        </repository>

That did not do the trick.     Right now. I'm pretty stuck on what I should do
next, and would be very grateful to whoever can help me spot my dumb mistake.

Re: [nexus-user] Trying to proxy a custom repository using
you might have to create two proxies, one for releases, and one for snapshots.

I did this and it worked okay.  be sure to clear your local maven cache between experiments (rm -rf .m2/repository/org/clojars).

you don't need any additional lines in settings.xml.

In reply to this post by Chris Bedford
The answer I got from Russ Tremain
was spot on.   I didn't do exactly what Russ suggested.. but i did notice that I was referencing a snapshot dependency, whereas I had registered clojars as a release repo. I changed the "policy" setting to snapshot... whacked my ~/.m2/repository directory to start fresh, and the build succeeded.

Thank you, Russ.

Re: Trying to proxy a custom repository using nexus. no luck so far.

Russ Tremain-2
[nexus-user] Re: Trying to proxy a custom repository using
good to know, Chris.

The tool hint in the nexus config says:

        "Repositories can store either all Release Artifacts or all Snapshot Artifacts"

Because the remote in this case includes both snapshots and releases, by setting your policy to snapshots, it seems that the proxy is picking up both.  so perhaps "release" policy really means " include releases but exclude snapshots", and snapshot policy means "include releases and snapshots".

Perhaps one of the experts at Sonatype could clarify...

Re: Trying to proxy a custom repository using nexus. no luck so far.

Rich Seddon
Snapshot proxies only allow snapshots, and release proxies only allow releases.

But maven-metadata.xml files at the GA level are neither snapshots nor releases, so they are always allowed through.

Because you did not specify a version in your  archetype:generate Maven downloaded this file to find highest version:

com/lackey/findFiles/maven-metadata.xml

The highest version was a snapshot, and then Maven tried to download: 

com/lackey/findFiles/1.0-SNAPSHOT/maven-metadata.xml

This was rejected, because it didn't match the proxy's policy.

good to know, Chris.

The tool hint in the nexus config says:

        "Repositories can store either all Release Artifacts or all Snapshot Artifacts"

Because the remote in this case includes both snapshots and releases, by setting your policy to snapshots, it seems that the proxy is picking up both.  so perhaps "release" policy really means " include releases but exclude snapshots", and snapshot policy means "include releases and snapshots".

Perhaps one of the experts at Sonatype could clarify...

Hi -


I am trying to configure nexus to proxy the repo http://clojars.org/repo/.
I added this repository as a proxy repository with the above URL.
I then added this proxy repository to the public  group.
When I did 'Browse Remote' and 'Browse Index' everything looked good.

But when I modify a very simple project to include
a dependency on a .jar that resides in the aforementioned repo, I get this error:


[ERROR] Failed to execute goal on project findFiles: Could not resolve dependencies for project com.lackey:findFiles:jar:1.0-SNAPSHOT: Failure to find org.clojars.brenden:storm-kafka-0.8-plus:jar:0.1.3-SNAPSHOT in http://dmip.buildserver.fairisaac.com:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]


I got this error as I was experimenting with
a very simple project which I created like this:

mvn archetype:generate -DarchetypeGroupId=org.codehaus.groovy.maven.archetypes -DarchetypeArtifactId=gmaven-archetype-basic -DgroupId=com.lackey -DartifactId=findFiles -Dpackage=com.lackey

To create my ~/.m2/settings.xml I followed these directions:
        http://books.sonatype.com/nexus-book/reference/maven-sect-single-group.html

Then I wiped out my ~/.m2/repository  and I verified that everything was downloading from my nexus server.   Good start.



Next I added a dependency on an artifact that resides in the clojars repo.

I modified my pom to include this :

          <dependency>
                <groupId>org.clojars.brenden</groupId>
                <artifactId>storm-kafka-0.8-plus</artifactId>
                <version>0.1.3-SNAPSHOT</version>
            </dependency>



Then I got the above error.

After I got the error I tried adding the config shown below (starting at NEW
addition)  to my settings XML file

      
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->

          <url>http://central</url>
          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </repository>

<!--   NEW addition.. did not work :^(    -->
        <repository>

            <releases><enabled>true</enabled></releases>
            <snapshots><enabled>true</enabled></snapshots>
        </repository>

That did not do the trick.     Right now. I'm pretty stuck on what I should do
next, and would be very grateful to whoever can help me spot my dumb mistake.

so what is the bottom line best practice for proxying mixed remote repositories?
Also, by "GA" level, I assume you mean the group-artifact level of the remote?

But maven-metadata.xml files at the GA level are neither snapshots nor releases, so they are always allowed through.

Because you did not specify a version in your  archetype:generate Maven downloaded this file to find highest version:

com/lackey/findFiles/maven-metadata.xml

The highest version was a snapshot, and then Maven tried to download:

com/lackey/findFiles/1.0-SNAPSHOT/maven-metadata.xml

The simplest thing to do is make both a snapshot and a release proxy and add both of these into your group repository.

Yup, that's right.
