在Mac上使用JRE打开jar文件 [英] Open jar file using JRE on Mac

问题描述

我有一个jar文件，可以通过命令行运行。

I have a jar file that is meant to be ran through the command line.

我不打算在应用程序所在的机器上进行任何java开发运行和我的思维过程是因为我应该只需要JRE而不是JDK。另外，JDK就像JRE一样大4倍，我不想下载它。

I am not planning to do any java development on the machines where the application will run and my thought process is that therefore I should only need the JRE and not the JDK. In addition, the JDK is like 4x as big as the JRE and I would like to not have to download it.

在Mac上安装JRE时，它没有设置java命令的路径，如果我尝试运行它，osx会提示我安装JDK。

When installing the JRE on a Mac, it does not set the path for the java command and if I try to run it, osx prompts me to install the JDK.

我想知道是否有人可以提供一些有关如何运行的见解在Mac中使用java命令而不下载更大的JDK？

I wonder if anyone could provide some insight as to how to use the java command in a mac without having the download the bigger sized JDK?

非常感谢。

推荐答案

您是否尝试在终端中运行此功能？

Have you tried running this in terminal?

java -jar MyJarName.jar

但是，您也可以尝试制作jar文件的可运行应用程序。请查看在Mac上打包Java App以进行分发

However, you can also try and make a runnable application of the jar file. Take a look at Packaging a Java App for Distribution on a Mac

编辑：
您也可以尝试从终端运行入门级。 cd 到项目的bin文件夹，然后 java packageName.className 。例如， java my.package.Starter 。

You can also try running your starter class from the terminal. cd to the bin folder of your project, then java packageName.className. For example, java my.package.Starter.
