近期在使用gradle，觉得他的task 脚本的方式很灵活，下面记录关于gradle相关的一些东西，后面也会不断补充，但详细解释或者是问题的答案还是建议查看文档

仓库指定

repositories {
    mavenLocal()
    repositories {
        mavenLocal()
        
        maven { url "http://repo.maven.apache.org/maven2" }
        maven { url "http://download.oracle.com/maven" }
        maven { url "https://palantir.bintray.com/releases" }
      }
    maven { url "http://repo.maven.apache.org/maven2" }
    maven { url "http://download.oracle.com/maven" }
  }

指定本地jar包

    compile fileTree(dir: project.projectDir.toString() + '/src/main/resources/libs', include: ['*.jar'])

scope相关

详细解释查看文档

dependency-management

spring提供的插件io.spring.dependency-management是的spring boot可以如maven dependency management方式一样添加依赖

java doc

gradle Java插件提供了java doc task的功能，配置如下：

configurations {
    docletJar
    javadocPath
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-web') {
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
    }
    compile('org.springframework.boot:spring-boot-starter-log4j:1.3.8.RELEASE')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile fileTree(dir: project.projectDir.toString() + '/src/main/resources/libs', include: ['*.jar'])

    //javadoc
    docletJar files('/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/lib/tools.jar')
    javadocPath('common:3.0-SNAPSHOT')
}

task generateRestApiDocs(type: Javadoc) {
    source = sourceSets.main.allJava
    options.docletpath = configurations.docletJar.files.asType(List)
    options.doclet = "com.eddy.Doclet"
    options.classpath = configurations.compile.files.asType(List)
    options.classpath.addAll(configurations.javadocPath.files.asType(List))
}

子工程

子工程信息配置在根目录的settings.gradle文件中，如下方所示：

rootProject.name = 'crawler4j-parent'
include ':crawler4j'
include ':crawler4j-examples-base'
include ':crawler4j-examples-postgres'

project(':crawler4j').projectDir = "$rootDir/crawler4j" as File
project(':crawler4j-examples-base').projectDir = "$rootDir/crawler4j-examples/crawler4j-examples-base" as File
project(':crawler4j-examples-postgres').projectDir = "$rootDir/crawler4j-examples/crawler4j-examples-postgres" as File

build生命周期

生命周期分为：初始化，配置。执行三个不同的阶段。

//settings.gradle

println 'This is executed during the initialization phase.'

//build.gradle

println 'This is executed during the configuration phase.'

task configured {
    println 'This is also executed during the configuration phase.'
}

task test {
    doLast {
        println 'This is executed during the execution phase.'
    }
}

task testBoth {
	doFirst {
	  println 'This is executed first during the execution phase.'
	}
	doLast {
	  println 'This is executed last during the execution phase.'
	}
	println 'This is executed during the configuration phase as well.'
}

Flat layout

includeFlat名称即文件夹，并且这些文件夹只能作为子目录的形式存在。
