Build in 8, run in 13

[John Kostaras <jk...@gmail.com>]

Hallo,

I wonder if you have come across this dilemma. I 'm trying to fix some bugs
in NetBeans JShell by using the NetBeans debugger. However, to build
the *jshell.support
*module, one needs to set the Java platform to 8, but in order to execute
it in debug mode, one needs to set the Java platform to 13 (or something
>=9 anyway). The problem is that then the debugger tries to build the
module again using JDK >=9 and of course it fails.
netbeans/nbbuild/templates/projectized.xml:74: You are attempting to build
NetBeans using JDK 9 (or higher).
This is forbidden as it may lead to accidental usage of JDK 9+ APIs.
Either run Ant with JDK 8, or set nbjdk.home=<JDK 8 home> in
/Users/MyMacBook/Projects/netbeans/incubator-netbeans/nbbuild/user.build.properties
(can be set from IDE by opening a module project's Properties dialog and
picking the right Java Platform in Libraries).
You can alternatively set this property in
/Users/MyMacBook/.nbbuild.properties to affect all checkouts on this
machine.
If you are sure you want to build with JDK 9+ anyway, use:
-Dpermit.jdk9.builds=true
BUILD FAILED (total time: 0 seconds)

I wonder where to add -Dpermit.jdk9.builds=true to. I tried in
project.properties
javac.compilerargs=-Dpermit.jdk9.builds=true -Xlint -Xlint:-serial

but it doesn't find it. Any suggestions are welcome.

Kind regards,

John.

In <netbeans-repo>/nbbuild I've got

    $ cat nbbuild/user.build.properties
    #nbjdk.home=F:/j/jdk/jdk1.8.0_241
    nbjdk.home=F:/j/jdk/jdk-13.0.2
    permit.jdk9.builds=true
