Answer 1

This is not an error, just a warning because the word "java.version" does not exist in the dictionary of eclipse.
To disable spell checking go to: Window -> Preferences, choose General, Editors, Text Editors, Spelling and disable spell checking.
I recommend using M2Eclipse when working with Apache Maven in Eclipse
