Unable to fetch maven dependencies from company's nexus repository

I am trying to build Spring Boot application which has several dependencies residing on maven public and company's Nexus Repository. But I get below error every time, I am trying to resolve the dependencies:

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

Surprisingly other developers in my team are able to fetch the dependencies without a glitch. In fact, the settings.xml is also same for all of us!!

Solution

  • I found the core issue. Actually, I had open my settings.xml file on 3 different editors which was getting overridden while I was doing the maven clean install. This inconsistency of file was throwing up this issue!!
