Building OpenCMIS hello world fails with Cannot find parent: org.apache.chemistry.opencmis:chemistry-opencmis_问答_开发者

I am trying to build the hello world for OpenCMIS that I found documented here:

http://chemistry.apache.org/java/developing/guide.html

I am very new to maven and somewhat confused by this error. Has any one else run into this? What was your fix. Below it the full output from trying to build. According to my understanding from the docs this is supposed to build and run the hello world.

As @Gagravarr has pointed out, 0.5-SNAPSHOT version of chemistry-opencmis is not available in maven central and hence the error. You should try using 0.4.0 version
