一、上传

build.gradle文件中添加：

//将源码打包
task androidSourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.srcDirs
}
//包含文档和源码的aar
artifacts {
    archives androidSourcesJar
}

二、下载

build.gradle文件中添加如：

implementation 'com.pi.pack.handwritedialog:handwritedialog:1.0.1-20200417.011048-19:sources@jar'

//或者

implementation 'com.pi.pack.handwritedialog:handwritedialog:1.0.1-SNAPSHOT:sources@jar'
