Java – Maven: no source compilation

I'm following "building Java projects with Maven"（ https://spring.io/guides/gs/maven/#scratch ）, when I run 'MVN compile' from / users / Misha / desktop / SRC / main / Java / Hello, I get this prompt:

[INFO] Scanning for projects...

I have two java files and XML files in the Hello directory. I assume I should see "Hello world!" Instead of no source compilation Why can't my java code compile? thank you!

Solution

To create a maven project you need

>Contains POM Project directory of XML file > under this project directory, a subdirectory Src / main / Java containing your Java code (package to the subdirectory Src / main / Java)

Call Maven to run MVN compilation or similar project directory
