Just go to the directory with "cd path to jar file".
And there you enter "filename.jar" and hit enter.
For me this works fine.
Edit: I put the "filename.jar" into brackets and the compiler did not show the filename.
只需转到带有“cd jar 文件路径”的目录即可。
在那里你输入“filename.jar”并按回车键。
对我来说这很好用。
编辑:我把“filename.jar”放在括号里,编译器没有显示文件名。
