Answer 1

Please follow the 2nd step given in the example. Then it should work.
Remove the parent entry in the pom.xml file that comes along with the sample. The contents of the pom.xml file will look similar to the following once you remove the parent entry. Alternatively, replace the contents of the pom.xml file with the following code snippet.
