Androd Studio用 gradle 构建项目

项目依赖关系如下：

一个公共Jar工程WhaleySystem，需要先编译出来WhaleySystem.jar，才能编译主App和无屏App_K.

1. settings.gradle文件

include ':eYourChat'
include ':WhaleySystem'
include ':eYourChat_K'

eYourChat 和 eYourChat_K 是（application）App，WhaleySystem 是 jar （library）工程。

2. build.gradle (Project: eYourChat_as )

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

此文件是整个Project的build.gradle，即根目录中的build.gradle

3. build.gradle (Module: eYourChat)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "26.0.3"

    defaultConfig {
        applicationId "com.xxx"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 47
        versionName 'eChat2.08.10.T10.05'

        applicationVariants.all { variant ->
            variant.outputs.all { output ->
                outputFileName = "${defaultConfig.versionName}_${releaseTime()}_${variant.name}.apk"
            }

        }

        //multiDexEnabled = true
    }

    signingConfigs {
        eChat {
            keyAlias 'mcptt'
            keyPassword 'Gotaxxxx'
            storeFile file('eChat.keystore')
            storePassword 'Gotaxxxx'
        }
    }

    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
            signingConfig signingConfigs.eChat
        }

        debug {
            minifyEnabled false
            signingConfig signingConfigs.eChat
        }
    }

    sourceSets {
        main{
            jniLibs.srcDirs = ['libs']
        }
    }
    lintOptions {
        abortOnError false
    }
}

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/baidumapapi_base_v4_1_1.jar')
    compile files('libs/baidumapapi_map_v4_1_1.jar')
    compile files('libs/baidumapapi_search_v4_1_1.jar')
    compile files('libs/baidumapapi_util_v4_1_1.jar')
    compile files('libs/Gotasystem.jar')
    compile files('libs/greendao-1.3.7.jar')
    compile files('libs/gson-2.2.1.jar')
    compile files('libs/isoviewer-1.0-RC-27.jar')
    compile files('libs/locSDK_6.13.jar')
    compile files('libs/okhttp-3.6.0.jar')
    compile files('libs/okio-1.11.0.jar')
    compile files('libs/picasso-2.4.0.jar')
    compile files('libs/systembartint-1.0.4.jar')
//    compile files('libs/multidex-1.0.2.jar')
    //compile project(':gotaSystem')
}

def releaseTime() {
    return new Date().format("yyyyMMdd-hhmmss")
}

此文件是Module eYourChat 有屏APP的 build.gradle文件

4. build.gradle (Module: eYourChat_K)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "26.0.3"

    defaultConfig {
        applicationId "com.ztegota.e180xx"
        minSdkVersion 8
        targetSdkVersion 17
        versionCode 36
        versionName 'eChat2.08.10.K9'

        applicationVariants.all { variant ->
            variant.outputs.all { output ->
                outputFileName = "${defaultConfig.versionName}_${releaseTime()}_${variant.name}.apk"
            }

        }
    }

    signingConfigs {
        eChat {
            keyAlias 'mcptte180'
            keyPassword 'gotaxxxx'
            storeFile file('e180Mcpttkeystore')
            storePassword 'gotaxxxx'
        }
    }

    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
            signingConfig signingConfigs.eChat
        }

        debug {
            minifyEnabled false
            signingConfig signingConfigs.eChat
        }
    }

    sourceSets {
        main{
            jniLibs.srcDirs = ['libs']
        }
    }

    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/Gotasystem.jar')
    compile files('libs/greendao-1.3.7.jar')
    compile files('libs/gson-2.2.1.jar')
    compile files('libs/locSDK_6.13.jar')
    compile files('libs/okhttp-3.6.0.jar')
    compile files('libs/okio-1.11.0.jar')
}

def releaseTime() {
    return new Date().format("yyyyMMdd-hhmmss")
}

此文件是Module eYourChat_K 无屏APP的 build.gradle文件

5. build.gradle (Module: WhaleySystem)

apply plugin: 'com.android.library'

android {
    compileSdkVersion 22
    buildToolsVersion "26.0.3"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 22

    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        }
    }

    lintOptions {
        abortOnError false
    }
}

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/aXMLRPC.jar')
    compile files('libs/fastjson-1.1.23.jar')
    compile files('libs/gcm.jar')
    compile files('libs/goso_framework.jar')
    compile files('libs/greendao-1.3.7.jar')
    compile files('libs/gson-2.2.1.jar')
    compile files('libs/locSDK_6.13.jar')
    compile files('libs/LteRilLib.jar')
    compile files('libs/okhttp-3.6.0.jar')
    compile files('libs/okio-1.11.0.jar')
    compile files('libs/pinyin4j-2.5.0.jar')
}


task buildJar(dependsOn: ['build'], type: org.gradle.jvm.tasks.Jar) {
    appendix = 'demo'
    baseName = 'androidJar'
    version = '1.0.0'
    classifier = 'release'
    extension = 'jar'
    archiveName = 'Gotasystem.jar'

    destinationDir = file('../eChat/libs/')

    def srcClassDir = [project.buildDir.absolutePath + '/intermediates/classes/release'];
    from srcClassDir
    exclude 'com/ztegota/BuildConfig.class'
    //exclude '**/R.class'
    //exclude '**/R\$*.class'
}

task buildJar_K(dependsOn: ['build'], type: org.gradle.jvm.tasks.Jar) {
    appendix = 'demo'
    baseName = 'androidJar'
    version = '1.0.0'
    classifier = 'release'
    extension = 'jar'
    archiveName = 'Gotasystem.jar'

    destinationDir = file('../eChat_K/libs/')

    def srcClassDir = [project.buildDir.absolutePath + '/intermediates/classes/release'];
    from srcClassDir
    exclude 'com/ztegota/BuildConfig.class'
    //exclude '**/R.class'
    //exclude '**/R\$*.class'
}

此文件是 Module WhaleySystem 公共jar工程文件的build.gradle。自定义了两个Task: buildJar /（buildJar_K） 用于拷贝编译好的jar到相应的lib目录下。

---

先编译jar包，在Android Studio 面板右上角有个Gradle图标，进入WhaleySystem，选择Tasks –> other –> buildJar / buildJar_K，可自动生成jar文件到有屏App / 无屏App目录下。
然后再执行 Build –> Rebuild Project 编译命令。
