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
- 可以添加在任意build.gradle里面，Project除外。
- 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。
- ./gradlew install 生成pom文件在build目录下
- ./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.
[EnvInject] - Injecting as environment variables the properties content
【1. 静态方法先执行】

Coverity Build Capture (64-bit) version 2017.07 on Linux 4.4.0-97-generic x86_64
Internal version numbers: 7a4de27b47 p-milo-push-30112.654
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：
- 静态方法先执行
- app/build.gradle先执行
- sdk引入的genPom.gradle执行
- 当所有gradle文件执行一遍后，开始构建。
- 各项目依次clean，相当于gradlew clean，构建前先清理。
- 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】 - 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】 - 如果在sdk/build后面添加脚本，则脚本在此时执行。
- 最后一个module构建完成，执行install。
