Getting error while trying to run SoapUI tests using Maven

Hi,

I am getting below error. searched the answers and hence added the depedencies in my pom.xml. The thing is when checked the URL from where it is downloading depedencies SoapUI is not mentioned there and only ReadyAPI is there.

[ERROR] Plugin com.smartbear.soapui:soapui-maven-plugin:5.3.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for com.smartbear.soapui:soapui-maven-plugin:jar:5.3.0: Could not transfer artifact com.smartbear.soapui:soapui-maven-plugin:pom:5.3.0 from/to maven-default-http-blocker (http://0.0.0.0/😞 Blocked mirror for repositories: [smartbear-sweden-plugin-repository (http://www.soapui.org/repository/maven2/, default, releases+snapshots)] -> [Help 1]
