1、新建模块

2、导入或新建代码

...

3、build.gradle构建

plugins {
    id 'java-library'
}

java {
    sourceCompatibility = JavaVersion.VERSION_1_7
    targetCompatibility = JavaVersion.VERSION_1_7
}


jar {
    manifest {
//运行时main函数的主类
        attributes 'Main-Class': 'com.XXX.XXX.XXXClass'
//运行时依赖
        attributes 'Class-Path': 'libs/activation-1.1.1.jar' +
                ' libs/commons-codec-1.13.jar' +
                ' libs/commons-collections4-4.4.jar' +
                ' libs/commons-compress-1.19.jar' +
                ' libs/commons-logging-1.2.jar' +
                ' libs/commons-math3-3.6.1.jar ' +

                ' libs/poi-4.1.1.jar'
    }
}

// 编译依赖

    api fileTree(include: ['*.jar'], dir: 'libs')
    api  'com.google.code.gson:gson:2.2.4'
