maven 配置 pom.xml 打包生成:單jar包/jar包+lib目錄

生成jar包 2種方式:
1.打包項目依賴的所有jar 生成單個jar包
2.生成jar包 復(fù)制所需的依賴jar包到lib目錄

Maven打包過程(順序)

  • clean清空之前生成的文件
  • IDE內(nèi)編譯該程序 (并測試可成功運行)-- 必須生成class文件!(等待被打包)
  • 確定文件pom.xml中的各項配置
  • Maven刷新:Reimport All Maven Projects
  • Maven自動打包:Install或package

可打包項目已經(jīng)編譯生成的class文件 + 依賴的jar包 --> 生成單個jar包(可獨立運行)

例1

下面這個pom.xml,可打包項目已經(jīng)編譯生成的class文件 + 依賴的jar包 --> 生成單個jar包(可獨立運行)
