As you've discovered, you can't have a source folder inside another source
folder, so before you can create src/main/java you have to tell Eclipse
not to treat src as a source folder. To do this,
right click on the src folder and select build path -> remove from build path.
Once you have done this src will appear in the folder tree in its normal place,
so you can create the main and java folders under it,
and move the existing src/com to src/main/java/com. Finally right-click the
newly-created java folder and select build path -> use as source folder.
