AndroidStudio之将工程生成jar

当我们准备好代码，准备生成jar时，AndroidStudio也需要配置下，因为AndroidStudio默认右边Gradle面板是没有生成jar的task的，如下：

解决办法：
依次点击：File -> Settings -> Experimental -> 取消勾选 “Do not build Gradle task list during Gradle sync”，如下图所示 ：



然后我们还要配置build.gradle如下：

plugins {
    id 'com.android.library'
}

android {
    compileSdkVersion 30

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles "consumer-rules.pro"
    }


    lintOptions {

        abortOnError false

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    task makeJar(type: Copy) {

        delete 'build/libs/myjar.jar'
        from('build/intermediates/aar_main_jar/release/')
        into('build/libs/')
        include('classes.jar')
        rename ('classes.jar', 'myjar.jar')
    }
    makeJar.dependsOn(build)
}

dependencies {

    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

jar包目录如下：
