摘要: Creating a src/main/java folder structure in Eclipse without Maven
How do I create the src/main/java and src/test/java in my default web application project in Eclipse without Maven? My current folder structure is TestApp -JavaResources - src - com.mypackage -WebContent Answers 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.
