Im building a small app in JavaFX using maven and openJDK 12. However, I need my .Jar to contain a bundled JRE so it can run on windows OS without downloading a proper JRE.
Im also using launch4j-maven-plugin
I tried several solutions here on SOF but no success. Some topics mentioned maven-shade-plugin but it didnt work for me. I couldnt pack external folders with it.
The current POM I have, do the job partially:
It packs the "C:/Program Files/Java/openjdk-12.0.2_windows-x64_bin/bin" folder inside the .jar but the ".exes" arent included, which is bad.
It packs the dependencies of POM inside the .jar
launcher4j-maven packs it all in a .exe
What I want is to pack the JRE inside the .jar and set launcher4J to use it. Would someone help me? I also need this to work because javaFX is being a pain to execute in users/clients computers.
Does the JRE has to be outside the .exe? if yes, then how can I set maven to do that for me?
