title: Spring toolsuite shows error on <execution> for maven-jaxb2-plugin
body: <p>I am using Spring Tool Suite version 3.7.0.RELEASE and I'm trying out an import of a WSDL offered by Amazon. The import succeeds, but Eclipse gives an error message on the  tag. </p>
  
  <p>I am using the following pom.xml:</p>
