下载java文件后打不开

Question

注意：这是在 mac 上

所以我最近下载了一个 java 文件，下载后我尝试打开它，它说无法打开 java jar 文件并检查控制台。查找教程后，我将以下命令输入终端。

Umairs-MacBook-Air:~ umairahmed$ java -version

java version "11.0.2" 2019-01-15 LTS

Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

Umairs-MacBook-Air:~ umairahmed$ java -jar/Users/umairahmed/Downloads/forge-1.12.2-14.23.5.2768-universal.jar 

Unrecognized option: -jar/Users/umairahmed/Downloads/forge-1.12.2-14.23.5.2768-universal.jar

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

我该如何解决？
