Artifactory unable to download Eclipse plugin's/artifacts. java.lang.SecurityException: class "org.eclipse.core.runtime.OperationCanceledException

I am facing two issues as explained below.

  1. java.lang.SecurityException: class "org.eclipse.core.runtime.OperationCanceledException"'s signer information does not match signer information of other classes in the same package

  2. Caused by: org.apache.maven.plugin.PluginResolutionException: Plugin org.eclipse.xtend:xtend-maven-plugin:2.12.0 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.eclipse.jdt:org.eclipse.jdt.core:jar:3.6.0, org.eclipse.platform:org.eclipse.core.runtime:jar:3.6.0: Could not find artifact org.eclipse.jdt:org.eclipse.jdt.core:jar:3.6.0

I understand that the resolution mentioned in the bug report [0] should ideally fix the issue. In order for that to happen, I need the bundles in #2, that apparently are not getting downloaded.

From the error log in #2, it's clear that the required dependencies cannot be found in the artifactory. What I do not understand is why these plugins are not getting provisioned? Provided below 1 is the list of P2 repositories that I have configured in the artifactory. I have confirmed that the required plugins are available for download in the below P2 repositories.

Any help/pointers are highly appreciated.

Tx in advance.
