不要再乱搞了，找不到第三方库(依赖)的类，直接使用shadow，只需两步，轻松愉快

1. 添加插件, build.gradle中添加插件

plugins {
    id 'com.github.johnrengelman.shadow' version '2.0.4'
    id 'java'
}

2. 等一会，使用下面的命令进行打包。
   

结果可以直接jar -jar运行了

完整的build.gradle文件

plugins {
    id 'com.github.johnrengelman.shadow' version '2.0.4'
    id 'java'
}

group 'org.springframework'
version '5.1.10.ZHONG-RELEASE'
sourceCompatibility = 1.8



jar {
// 指定主类信息。
   manifest {
        attributes 'Main-Class': 'com.fuzekun.springTest.importSelector.TestMain'
    }
}
