Java HotSpot(TM) 64-Bit Server VM (build 15.0.1+9-18, mixed mode, sharing)Ģ.I typed echo $JAVA_HOME and answer was nothing:ģ.I typed the code that starts the file - java -jar. Java(TM) SE Runtime Environment (build 15.0.1+9-18)
The JDK version (designed for developers) works 10x better even for a non-developer just trying to run a Jar file. It often doesn't set up Java home location properly. The normal runtime version of Java (the "JRE") really stinks. 99% of the time this is going to fix the problem. You'll need to make a free Oracle website account. Just select to install the macOS 64-bit version of the JDK (not the normal runtime JRE). Generally though, and if this is too much for you, the easy solution is going to be to install or reinstall the Java JDK. and then drag the icon for your JAR file into the terminal window and it will autocomplete path of the JAR file into the terminal window and you can just hit enter. Tip: If you aren't comfortable with terminal and navigating folder locations you can type: If those both give some specific output indicating the version and home directory comes back with some kind of non-empty response, you can use terminal to launch the jar file directly: Type in:ĭid this output your current have version?ĭid this output a specific directory that's your Java home files location?
