Nexus can not download dependencies of spring-boot-CodePudding

I am using a nexus, which i did not configure. I log in with remote desktop on the system that runs windows server 2012. When i want to build my spring-boot application and i run the goal mvn clean package it downloands several dependencies and then fails with a connection refused error. I do not understand this. Why was is possible to download the first few, but not the spring-boot-starter-aop jar? What connection is refused? The one that is used to download the otheres? Here is my error report:

CodePudding user response：

It is not downloading any of them.

If you look at the order, it is actually failing for the first one Downloading: http://192.168.1.142:8081/nexus/content/groups/public/org/aspectj/aspectjweaver/1.9.6/aspectjweaver-1.9.6.pom.

It is telling you it is downloading, but then during the first attempt it fails to connect.

My suggestion is to try the URL on your browser without maven first to see if you can access it: http://192.168.1.142:8081/nexus/content/groups/public/ in the browser

If download was successfull of any of those dependencies, you would see (downloading/downloaded)
