Java Eclipse:导出为 JAR 和导出为 Runnable JAR 之间的区别 [英] Java Eclipse: Difference between exporting as a JAR and exporting as a Runnable JAR

问题描述

eclipse 中导出为 JAR 文件和导出为 Runnable JAR 文件有什么区别?他们不是都可以运行吗?各自的优缺点是什么?

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?

推荐答案

runnable jar 包含一个 MANIFEST.MF 文件，该文件定义了运行 jar 时要执行的 Main 类.

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

不可运行的 jar 只是类库，可以将其添加到类路径中以便重用代码(它还包含清单文件，但没有主类)

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)
