IDEA导出JAR包

进入Project Structure > Artifacts -- 添加 > JAR > From modules with dependencies.... 

 

导出为可执行JAR需要设置Main Class,作为JAR程序入口.

一般工具JAR可以不设置Main Class.

 

选择extract to the target JAR 会将所有buildpath中的JAR引用都打在一个JAR中

选择copt to the output directory and link via manifest会按照.MF文件中自定义的格式来打包

 配置好后,通过 Build > Build Artifacts 选择配置的JAR, build\rebuild;JAR文件会被创建在输出文件夹中.
