1.在项目中添加module
2.选择android library
3.给library命名
4.在java目下放入要打包成jar的包
5.在dtlslibrary下面的build.gradle 添加
task makeJar(type: Copy) { delete 'build/libs/mysdk.jar' from('build/intermediates/bundles/release/') into('build/libs/') include('classes.jar') rename ('classes.jar', 'dtls.jar') } makeJar.dependsOn(build) //在终端执行生成JAR包 // gradlew makeJar 高版本临时生成的路径在：from('build/intermediates/bundles/default/')6.在终端执行
注意：如果报类似错误

这个错误是gradle不完整导致的，请到下面网站下载对应的gradle压缩包放到提示的目录下
