1.gradle 3.1 后build module后在build文件找不到j(luò)ar文件的路徑，只能找到aar的文件

2.我們可以拿到aar文件的jar文件使用

moduel:build.gradle 我們可以這樣:

//aar的文件路徑

def zipFile = file('build/outputs/aar/xxxx-release.aar')

//解壓得到的jar的文件路徑

def unzipFile = file('build/outputs/xxxx/classes.jar')

task makeJar(type: Jar) {

//解壓aar拿到里面的jar文件跟assets資源文件

? ? ? ? copy {

????????????????????from zipTree(zipFile)

????????????????????from fileTree(dir: 'src/main', includes: ['assets/**'])

????????????????????into('build/outputs/xxxx/')

????????????????????include('classes.jar')

????????????????????include('assets/**')

????????}

????????from zipTree(unzipFile)

? ? ????from fileTree(dir: 'src/main', includes: ['assets/**'])

????????baseName = SDK_BASENAME + SDK_VERSION

????????destinationDir = file("build")

}

makeJar.dependsOn(build)
