Maven "peer not authenticated" errorcom/day/jcr/vault/multimodule-content-package-archetype while generating archetype

[jayproulx]

I've tried generating a project from an archetype this morning, and I'm getting the following results.  I've also seen other errors trying to build an existing project, but I'll start here as this is probably the easiest entry point.  I've tried a few things, from using http://repo.adobe.com (as specified in the settings on that page), to specifying https://repo.adobe.com, installing the SSL cert locally and trusting it, etc. I can download quite a few dependencies from repo.adobe.com, but some of them fail with this error message.

Here's the error:

jproulx-mpb15r:temp jproulx$ cat ~/.m2/repository/com/day/jcr/vault/multimodule-content-package-archetype/1.0.2/multimodule-content-package-archetype-1.0.2.jar.lastUpdated #NOTE: This is an internal implementation file, its format can be changed without prior notice. #Mon Apr 20 15:00:44 EDT 2015 default-http\://repo.adobe.com/nexus/content/groups/public/.lastUpdated=1429556443809 http\://repo.maven.apache.org/maven2/.lastUpdated=1429555415785 default-adobe-public-releases/.lastUpdated=1429555439318 default-https\://repo.adobe.com/nexus/content/groups/public/.lastUpdated=1429556444161 http\://repo.maven.apache.org/maven2/.error= adobe-public-releases/.error=Could not transfer artifact com.day.jcr.vault\:multimodule-content-package-archetype\:jar\:1.0.2 from/to multimodule-content-package-archetype-repo (adobe-public-releases)\: No connector available to access repository multimodule-content-package-archetype-repo (adobe-public-releases) of type default using the available factories WagonRepositoryConnectorFactory https\://repo.adobe.com/nexus/content/groups/public/.error=Could not transfer artifact com.day.jcr.vault\:multimodule-content-package-archetype\:jar\:1.0.2 from/to adobe-public-releases (https\://repo.adobe.com/nexus/content/groups/public)\: peer not authenticated http\://repo.adobe.com/nexus/content/groups/public/.error=Could not transfer artifact com.day.jcr.vault\:multimodule-content-package-archetype\:jar\:1.0.2 from/to multimodule-content-package-archetype-repo (http\://repo.adobe.com/nexus/content/groups/public/)\: peer not authenticated

What document are you following. I just tested this Maven AEM project listed in this community article:

https://helpx.adobe.com/experience-manager/using/creating-aem-project-using-intellij.html

The Maven command is:

mvn archetype:generate -DarchetypeRepository=http://repo.adobe.com/nexus/content/groups/public/ -DarchetypeGroupId=com.day.jcr.vault -DarchetypeArtifactId=multimodule-content-package-archetype -DarchetypeVersion=1.0.2 -DgroupId=com.aem.community -DartifactId=echoproject -Dversion=1.0-SNAPSHOT -Dpackage=com.aem.community -DappsFolderName=myproject -DartifactName="My Project" -DcqVersion="5.6.1" -DpackageGroup="My Company"

It works as expected.

Thanks for the follow up Scott!

I’m following the docs here:  https://docs.adobe.com/docs/en/aem/6-0/develop/dev-tools/ht-projects-maven.html

It’s definitely something in my maven stack, if I wget the archetype dependency and copy it manually into .m2/repository it’ll work.  That’s obviously not sustainable for all affected dependencies.

The archetype itself is not my primary concern, it’s the error I’m getting (the "peer not authenticated” error) that affects my other builds that I’m trying to troubleshoot.

The latest things I’ve tried are importing the chain for the repo.adobe.com SSL cert into my cacerts keystone, with the same results.  I’ve also tried:

 -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true

But that gives me a different error.

The only thing that I’ve got on this machine (new for development) is Maven 3.0.5, and the repo.adobe.com settings.xml.  I’ve never needed to go to such an extent to set up my development environment before which leads me to believe the problem is somewhere else.

[jayproulx]

I upgraded to a JDK8 and the issue doesn't seem to reproduce...  I'm going to assume that the cert chain (somewhere in that cert chain) that was in the default OSX 1.6 JDK didn't align with the SSL cert for repo.adobe.com.

So, my issue is resolved, but it might be worth a quick pass over the docs.adobe.com content and make sure it still works with older JDK's...  especially now that 6.0 SP1 supports JDK8, you might need to bump the minimum JDK requirements for development...

I am also facing same problem and even upgrading to JDK 8 is not working for me.

Look at AEM docs 

PREREQUISITES

• The Java Runtime Environment (JRE). Version 1.7 is preferred.

[RK30]

yes, we are still using 1.7 but after this error started appearing trying to fix these. Previously same build was working but all of a sudden started getting these errors.

[RK30]

Even if I try to go to 'http://cwiki.apache.org/confluence/display/MAVEN/PluginManagerException' ut says Page not found.

[jayproulx]

@RK30, @smacdonald2008 I should have replied back here.  The problem is when you’re using OpenJDK, it’s missing certificates in the certificates chain that Nexus uses.  Use an official Oracle JDK release and you should be fine.  I can’t comment on JDK 1.7 (AEM 6 SP1+ recommends 1.8), but this has reproduced on all of our build machines.

[RK30]

@jayproulx that for your reply, we are using oraclejdk/1.7.0_80
