title: Maven: No sources to compile
body: <p>I am following the 'Build Java Projects with Maven' (<a href="https://spring.io/guides/gs/maven/#scratch">https://spring.io/guides/gs/maven/#scratch</a>) and when I run 'mvn compile' from /Users/Misha/Desktop/src/main/java/hello, I get this prompt:</p>

  <p>I have the two java files and the xml file in the hello directory, and I am assuming that I should see "Hello World!" instead of No sources to compile. Why is my java code not compiling? Thanks!</p>
