Maven build failure: Read time out

Question

I have tried all the possible solutions found here, including:

1. find ~/.m2 -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;
2. mvn -U clean

It does not work anyway, the specific log is as below:

btw: I was trying to run a struts2 sample code from mkyong site

Answer 1

Read Timeout errors can also happen with big dependency resolution on slow networks (that you may not be able to fix by yourself). You may also want to consider this other thread, here you will find how to increase the Maven Wagon timeout which will help you in such cases.

Also check the official documentation for more details.
