How can I stop the Minecraft Launcher from downloading java?

Every time I launch the new native Minecraft launcher it downloads java, and right after that I delete it. I already have java installed, I don't want it to be installed again. I also already have my profile set to use my already-installed java, it works fine.

How can I stop it from downloading the java runtime every time I start it?

Solution 1:

You cannot. The real question is why you care, this version is only used by the game itself and cannot be used to open other executable JAR files. EDIT: it may be possible to place another executable as a placeholder, so Minecraft thinks that the JRE is there, but it is not.
