Unable to download Maven dependency - AnypointStudio

Question

I am running into an issue where I am unable to download dependencies properly for my Mulesoft project. I have successfully installed everything from my home PC, but my work PC seems to be struggling.

Things I have tried:

mvn clean install
mvn clean install -U
mvn compile
Everything that is involved with setting 'Anypoint Studio (Mulesoft Eclipse IDE)' up to use Maven and the appropriate JDK.
I have tried creating truststore and adding the appropriate certificates to the repositories - I have also made sure to configure the AnypointStudio.ini file to point to this truststore.
Deleting .m2 folder, also tried deleting the files specifically.
I am able to access the repositories directly through the browser.

This is the error I am getting, I feel like it is seperate from AnypointStudio and strictly has to do with Maven.

Downloading from mulesoft-release: http://repository.mulesoft.org/releases/org/mule/tools/maven/mule-app-maven-plugin/1.2/mule-app-maven-plugin-1.2.pom Downloading from central: https://repo.maven.apache.org/maven2/org/mule/tools/maven/mule-app-maven-plugin/1.2/mule-app-maven-plugin-1.2.pom [ERROR] [ERROR] Some problems were encountered while processing the POMs: [ERROR] Unresolveable build extension: Plugin org.mule.tools.maven:mule-app-maven-plugin:1.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.mule.tools.maven:mule-app-maven-plugin:jar:1.2 @ [ERROR] Unknown packaging: mule @ line 9, column 16

I am finding that when I try to install any of these dependancies I end up with files that are appended with .lastUpdated.

I am just looking for more ideas on how I can resolve this, does anyone have an idea?

mvn clean install -X

Run maven with `-X` or `--debug`, to obtain more information about the problem. — Ortomala Lokni, Oct 07 '18 at 20:43
Are you behind a proxy? If you provided the pom.xml it would me easier to find a solution — Álvaro Pérez Soria, Oct 08 '18 at 01:39

The root error is visible if you scroll to the right of the last exception:

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

This is probably caused by some network proxy or firewall. You can try changing the protocol for the Mule repository to https (eg: https://repository.mulesoft.org/releases/) as that avoids a protocol redirection that confuses some proxies. If that fails you'll probably have to ask your network administrators to whitelist the URL for the repository.
