so, before trying your suggestion, i tried to build with the version that works with java 11+. i tried with 19, 14 and 11. all gave same result as before;
Starting step: Compiling Java code.
javac 11.0.1
Completed successfully.
Starting step: Creating jar file.
Completed successfully.
Starting step: Creating XML file.
error: option --boot-class-path not allowed with target 11
Error.
is anyone other than me testing with b4a 13? i was testing using actual projects, so i decided to try with the firstlibrary example included with the tool. as you may know, it doesn't even compile, due to a "slip of the kotlin" in the last method. no one else is mentioning this. what are others testing? i can't get either version to work.
with luck, erel is checking this thread occasionally. in any case, thanks for your efforts.
