I get this error when compiling Maven project. Can someone tell me what is wrong? By the way I'm in China (Great Firewall block) - is this why Maven dependency can't be downloaded?

Probably. Your DNS seems to have resolved repo.maven.apache.org to 127.0.1.2 (which is part of the "loopback" IP block 127.0.0.0/8), so not a routable internet address but meaning "yourself" (your computer).
1. try to click on https://repo.maven.apache.org/maven...aven-plugin/1.5.0/exec-maven-plugin-1.5.0.pom and see whether you get an XML result
2. if not: check `nslookup repo.maven.apache.org`

Not XML, just some text like this: 4.0.0 org.codehaus.mojo mojo-parent 38 exec-maven-plugin 1.5.0 maven-plugin Exec Maven Plugin A plugin to allow execution of system and Java programs http://www.mojohaus.org/........ and so on....
Thanks. Nevermind. I have to leave this hole to do some serious programming, nothing works here.

Probably your browser doesn't display XML tags. At least it seems to be the correct file with XML tags missing.
