Can I pass JVM args to the application?

[dawidcxx]

I would like to use G1GC for my application. Can this be done with a non native launcher? I tried a line like this in my gradle (kts)

fxlauncher {
  applicationParameters = "-XX:+UseG1GC"
}

but sadly that didn't work.

Yes, since javapackager supports the jvmOptions=option parameter, you can configure that in the javapackagerOptions section :)

How to add this arguments for virtual keyboard: -Dcom.sun.javafx.isEmbedded=true -Dcom.sun.javafx.touch=true -Dcom.sun.javafx.virtualKeyboard=javafx

fxlauncher { ... javapackagerOptions = ['-Dcom.sun.javafx.isEmbedded=true', '-Dcom.sun.javafx.touch=true', '-Dcom.sun.javafx.virtualKeyboard=javafx'] } I tried with javapackagerOptions, but it doesn't work.

Have a look in the documentation for javapackager: https://docs.oracle.com/javase/8/docs/technotes/tools/unix/javapackager.html

jvmOptions=option

Option to be passed to the JVM when the application is run. Any option that is valid for the java command can be used. To pass more than one option, use multiple instances of the -B option, as shown in the following example:

    -BjvmOptions=-Xmx128m -BjvmOptions=-Xms128m

That should do it :)
