Java Eclipse：导出为JAR并以Runnable JAR导出之间的差异 [英] Java Eclipse: Difference between exporting as a JAR and exporting as a Runnable JAR

问题描述

导出为JAR文件并导出为Runnable JAR文件时，eclipse有什么区别？他们不是都可以运行吗？

解决方案

可运行的jar包含一个MANIFEST.MF文件，它定义了Main类在运行jar时执行。

不可运行的jar只是类的库，可以添加到类路径中，以便代码被重用（它还包含清单文件，但没有主类）

What is the difference in eclipse between exporting as a JAR file and exporting as a Runnable JAR file? Aren't they both runnable? What are the pros/cons of each?

解决方案

The runnable jar contains a MANIFEST.MF file, which defines the Main class to be executed when the jar is run.

Non-runnable jars are just libraries of classes, that can be added to the classpath so that code is reused (it also contains the manifest file, but no main class there)
