NetBeans 12 doesn't manage libraries anymore

A week ago I upgraded my Java IDE to Netbeans 12 (and JDK 14), and only yesterday I noticed the window Project Properties (MYPROG) lacks of essential functionality i.e. there are not lines for compiling in *.jar, and mostly there is not any line for adding *.jar libraries, there is instead an empty line for JavaScript libraries, and it is impossible to add them in any other point.

The real oddity of NetBeans 12 is that it works perfectly even with old projects made with NetBeans 8 and JDK6! but reinstalling previous NetBeans 10 still remaisn a trouble. I'm stuck making new projects that need libraries. Minor problems are: System.err.println doesn't write in red colour, the path src/mycode has become src/main/java/mycode, why? and perhaps many others. My attempts are over. I've installed

  • OS: Window 10
  • jdk-14_window-x64_bin.exe
  • Apache NetBeans 12 LTS
  • Binaries: netbeans-12.0-bin.zip (SHA-512, PGP ASC) 1st try
  • Installers: Apache-NetBeans-12.0-bin-windows-x64.exe (SHA-512, PGP ASC) 2nd try.

It's a Java project using Maven

I don't know Gradle and Ant (what are they for?)

  • Project Properties (MYPROG)-->Build has only Compile without Compiling, Packaging, Deployment, Documenting
  • Project Properties (MYPROG)--> Libraries does not exist instead: JavaScript libraries (empty)

When you are using Maven, the Project properties do not have a Libraries section, because the libraries are managed through Maven (and not NetBeans).

You manage the needed libraries through the "Dependencies" node of the project or by editing pom.xml directly:

But this has been the case since NetBeans started supporting Maven (so probably 8.0 or something along those lines). If you had a "Libraries" section in the project properties before, you were using an Ant based project.

path src/mycode has become src/main/java/mycode, why?

Because src/main/java is the default directory layout Maven uses.
