Answer 1

The message says there's a duplicate <build> tag in your pom.xml at line 65:
Duplicated tag: 'build' (position: START_TAG seen ...\n\n\t... #65:9)
However, the pom.xml you posted is totally fine. Maybe you have another pom.xml in your project somewhere?

Answer 2

The pom file has an error in it. In my case, an opening tag did not match the closing tag.
I found the exact problem by creating a new java project and then copying the pom file to there. When I tried to open the pom file, Eclipse gave a message stating the exact error that was preventing the pom file from being read.
