jar 运行清单文件MANIFEST.MF生成定义Main-Class Premain-Class IDEA maven-assembly-plugin

可运行jar文件中的启动清单文件 META-INF/MANIFEST.MF 内容自定义生成

清单文件中的 Main-Class: Premain-Class: Can-Retransform-Classes: 在maven-assembly-plugin插件中的生成配置如下, 注意命名

<mainClass>cn.tekin.burploaderkeygen.KeygenForm</mainClass>

</manifest>

<Premain-Class >cn.tekin.burploaderkeygen.Loader</Premain-Class>

<Can-Retransform-Classes>true</Can-Retransform-Classes>

</manifestEntries>

</archive>

打包jar文件夹后生成的清单如下:

Main-Class: cn.tekin.burploaderkeygen.KeygenForm

Can-Retransform-Classes: true

Premain-Class: cn.tekin.burploaderkeygen.Loader

总结:

从上面可以得出主入口类的定义在manifest节点,且命名为小驼峰(配置 mainClass 最后生成 Main-Class ), 其他的清单配置都定义在manifestEntries节点,命名方式为首字母大写加连接线-的方式
