What is the purpose of the dx.jar file that I see in some of Android SDK versions that I've installed with the Android SDK manager; the file appears under tools/lib/dx.jar I do NOT see the file in versions above android-8 and above. However Intellij IDEA gives an error when I try to build a project with android-8 and above, saying that dx.jar doesn't exist. What gives?

Thanks, Tom

java android intellij-idea
