Gradle

笔记修正记录）2022.1.22

Gradle需掌握的知识点涵罗列：是什么。如何选择Maven和Gradle。如何使用。 Gradle is a general-purpose build tool。The core model is based on tasks。Gradle has several fixed build phases。.Gradle is extensible in more ways than one。Build scripts operate against an API。
【Gradle 是什么/简介】Gradle 的核心在于基于 Groovy 的丰富而可扩展的域描述语言(DSL) Groovy 通过声明性的语言元素将基于声明的构建推向下层，你可以按你想要的方式进行组合， 并且，这种声明性的语言是可以扩展的。你可以添加新的或增强现有的语言元素。Gradle 自带了很多插件，Java plugin 作为其中之一，为你提供了诸如编译，测试，打包等一些功能。Java 插件为工程定义了许多默认值。Gradle runs on the JVM you can use the standard Java APIs in your build logic, such as custom task types and plugins.
【Gradle的Task】Task是什么/用来做什么，
【如何编写Task、Task基本语法】Tasks themselves consist of: Actions、Inputs、Outputs 。They are optional depending on what the task needs to do
【学习Gradle现存疑问】？？task是要写在build.gradle。task copy好像要用from into关键字。task语法疑惑，task代码块括号中type和depends on？？ 这个type和depends on撒意思.Gradle 文档中，Copy或Zip文档部分的properties 和method啥意思。如何依据文档，写出一个
【build.gradle文件】：build.gradle 文件中都写啥：task，dependencies、plugins，repositories、sourceSets。build scripts describe what steps are needed to build the software, not how those steps should do the work. That’s a job for custom task types and plugins. build scripts can also use the standard Java API.
settings.gradle
【Gradle插件】Gradle java插件：Java插件是构建JVM项目的基础，它为项目增加了很多能力，例如编译，测试，打包，发布
【idea中使用Gradle】idea官网Gradle教程https://www.jetbrains.com/help/idea/gradle.html
创建project时选择Gradle。build.gradle文件和settings.gradle。idea右侧的Gradle工具栏。
【Gradle依赖管理】参考官网
【Gradle基本插件】(Gradle base plugin) Gradle base plugin是干啥的：The base Plugin provides some tasks and conventions that are common to most builds and adds a structure to the build that promotes consistency in how they are run. Its most significant contribution is a set of lifecycle tasks that act as an umbrella for the more specific tasks provided by other plugins and build authors.
【Gradle如何构建项目】三个阶段Initialization、Configuration、Execution.Gradle models its builds as Directed Acyclic Graphs (DAGs) of tasks (units of work). once the task graph has been created, Gradle determines which tasks need to be run in which order and then proceeds to execute them.Almost any build process can be modeled as a graph of tasks in this way。task graph can be defined by both plugins and your own build scripts, with tasks linked together via the task dependency mechanism.You choose which task to run. Save time by specifying the task that does what you need, but no more than that. If you just want to run the unit tests, choose the task that does that — typically test. If you want to package an application, most builds have an assemble task for that. 构建项目的本质：a build essentially configures a set of tasks and wires them together — based on their dependencies。
