Error:
---
Errors occurred during the build.
Errors running builder 'Maven Incremental Builder' on project '[PROJECT NAME]'.
java.lang.NullPointerException

I have reproduced this on several machines and the step to reproduce is to create a property that has a valid, XML-escaped ampersand.  Example:
<project>
...
  <build>
  ...
    <properties>
      <my.jdbc.url>jdbc:mysql://localhost/didiapply?characterEncoding=utf8&amp;characterSetResults=utf8</my.jdbc.url>
    </properties>
  </build>
</project>

Just removing the query string and re-importing the project solves the problem.
