Hi @tosone

• I see quite a few files with changes to path with comments "File renamed without changes." I think those are by mistake here
• I don't see any difference in server.java or in the example hello world class - so technically would the same Spring environment which is available would work with Gradle built functions too?
• There is a file java-maven-spring/examples/java/specs/README which seems misplaced
• Also changes to file environments-ui/src/resources/environments.json needs fixing - there are many changes which are not needed.

Left comments in PR I think this needs some work
