I ran into this a few weeks ago using Coolbeans:


We have an RCP application that I was trying to create an installer for (right 
click the project, Package As->Installers). The build was failing with the 
following error:

-do-compile:
    [mkdir] Created dir: 
C:\Users\wnreynolds\Desktop\Work\<deleted>\build\installer\nbi_all\ext\infra\build\products\helloworld\build\ext\components\products\helloworld\build\empty
    [javac] Compiling 2 source files to 
C:\Users\wnreynolds\Desktop\Work\<deleted>\build\installer\nbi_all\ext\infra\build\products\helloworld\build\ext\components\products\helloworld\build\classes
    [javac] error: Source option 5 is no longer supported. Use 6 or later.
    [javac] error: Target option 1.5 is no longer supported. Use 1.6 or later.

I don't have a deep understanding of the build harness, but it looked like an 
empty application, helloworld, was being added to the installer, and the 
compile was failing it due to too low a javac.{source,target} specification.

Setting javac.{source,target}=1.8 in my toplevel project.properties didn't fix 
the problem.

Editing CoolBeans\harness\nbi\stub\ext\components\products\helloworld\nbproject\
project.properties and changing javac.source=1.8 javac.target=1.8 fixed the 
problem.

I know folks are managing a lot of changes with the move to apache, and this is 
a little problem, but it should be simple to fix and will save others the 
couple of hours I took to track it down.

Thanks for your work.

thanks for the answer. With JDK 11 I'm still getting the same error.

Yes,as far as I know, the installers can't be built with JDK 11 yet.
See pending PR https://github.com/apache/netbeans/pull/1414

Best wishes,

Neil
