Gradle脚本

AndroidStudio项目结构：

- Project
   - application app
   - module sdk
   - module 3rd
   - module net
   ....

上面的Project／Application／Module都具有自己的build.gradle配置文件。真正能构建的好像只能在Application或Module，在Project里面部分命令是不支持的。

对于Module而言，在build过程，和Application对象几乎一样。

project对象

  1. 可以添加在任意build.gradle里面，Project除外。
  2. 对于Application或Module，都指向当前Application或Module对象。不能跨域。比如，application app中project是app模块；module sdk中project是sdk模块；并不能通过app模块访问到sdk模块。
build {
    doLast {
        def appName = "app"
        def moduleName = "rpcservice"
        def buildDir = project.projectDir.path+"/../";
        println buildDir
        def fromFile = buildDir + moduleName+"/build/outputs/aar/" + moduleName + "-release.aar"
        def intoFile = buildDir + appName + "/build/outputs/aar/"
        println fromFile
        println intoFile
        copy {
            from fromFile
            into intoFile
            rename {
                appName + "-release.aar"
            }
        }
        println("=====================build.doLast success.=========================")
    }
}

以上脚本代码，可以添加到Application或Module里，Project不支持。

rootProject对象

println project.rootProject.projectDir.absolutePath;

copy&rename

坑爹的copy&rename，因为不提供复制时直接改变文件名。只能将文件复制到目录，然后再修改名称。

 copy {
            from fromFile
            into intoFile
            rename {
                appName + "-release.aar"
            }
 }

task copyTmpChangelog(type: Copy) {
  from "input"
  into '.'
  rename { String fileName ->
    fileName.replace("input", "output")
  }
}

static静态方法

static def genVersionName() {
    String versionName = System.getenv("VERSION_NAME")
    if (versionName != null) {
        return versionName
    } else {
        return "UNDEFINED"
    }
}
def _versionName = genVersionName()

ext 全局变量区

ext {
    bintrayRepo = 'maven'
    bintrayName = 'appswitcher'
    bintrayOrg = 'inmarket'
    versionName = "1.0.0"

    publishedGroupId = 'com.inmarket'
    libraryName = 'appswitcher'
    artifact = 'appswitcher'

    libraryDescription = 'App switching library for Android'

    libraryVersion = '1.0.0'

    developerId = 'zaidd'
    developerName = 'Zaid Daghestani'
    developerEmail = 'zdaghestani@inmarket.com'

    licenseName = 'The Apache Software License, Version 2.0'
    licenseUrl = 'http://www.apache.org/licenses/LICENSE-2.0.txt'
    allLicenses = ["Apache-2.0"]
}

gradlew 命令

坑爹的gradle需要本地安装才能用，而gradlew则不需要，使用gradle会出现各种版本不对的错误，而gradlew则没有。所以放弃使用gradle吧。

  1. ./gradlew install 生成pom文件在build目录下
  2. ./gradlew build 构建所有版本

Pom文件

archivesBaseName = "libqrcodeshare"

maven插件文档https://docs.gradle.org/current/userguide/maven_plugin.html，里面有说明，gradlew install是执行生成pom文件。

以上gradle，执行结果：


[EnvInject] - Executing scripts and injecting environment variables after the SCM step.
[EnvInject] - Injecting as environment variables the properties file path 'gradle.properties'
[EnvInject] - Variables injected successfully.
[EnvInject] - Injecting environment variables from a build step.

【1. 静态方法先执行】

LIB_NAME=LibRpcService_master

To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/4.2/userguide/gradle_daemon.html.
Daemon will be stopped at the end of the build stopping after processing

【2. app/build.gradle中的方法执行】
****************BUILD_TAG is jenkins-write_display-write_display_common_library-LibRpcService_master-13*****************

Configuration 'compile' in project ':app' is deprecated. Use 'implementation' instead.

WARNING [Project: :sdk] Support for not packaging BuildConfig is deprecated.

Configuration 'compile' in project ':sdk' is deprecated. Use 'implementation' instead.
                        
【3. sdk／genPom.gradle执行】

大致流程：

  1. 静态方法先执行
  2. app/build.gradle先执行
  3. sdk引入的genPom.gradle执行
  4. 当所有gradle文件执行一遍后，开始构建。
  5. 各项目依次clean，相当于gradlew clean，构建前先清理。
  6. 接下来依次执行，从Application app到Module sdk。
    【app】【gradlew assemble】
    【app】【gradlew lint】
    【app】【gradlew check】
    【app】【gradlew build】
  7. 如果在app/build后面添加脚本，则脚本在此时执行（上面的 build { doLast{ } }只是针对当前Project或Module的构建过程，并不是指整个项目构建完成。）
    【sdk】【gradlew assemble】
    【sdk】【gradlew lint】
    【sdk】【gradlew check】
    【sdk】【gradlew build】
  8. 如果在sdk/build后面添加脚本，则脚本在此时执行。
  9. 最后一个module构建完成，执行install。
