Spring-boot 2.3.x原始碼基於Gradle編譯過程詳解

阿新 • • 發佈：2020-12-07

spring Boot原始碼編譯

1. git上下拉最新版的spring Boot

下載：git clone [email protected]:spring-projects/spring-boot.git，建議下載release版本，不會出現奇奇怪怪的錯誤

在這裡插入圖片描述

2.修改下載源，

gradle\wrapper中的配置檔案

gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
#distributionUrl=https\://services.gradle.org/distributions/gradle-6.4-bin.zip
//這裡Gradle換成你自己存放gradle的路徑以及gradle的壓縮包名
//這裡需要注意的是gradle版本問題，儘量高一點兒，就是用了gradle-4.9的版本，導致報錯gradle-api plugins問題，還缺包啥的，換了包之後就沒問題了
distributionUrl=file:///E:/Gitee_repository/Java_Sources_Code_Study/Spring-Boot-2.3.1/gradle-6.5.1-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

buildSrc下的build.gradle

plugins {
	id "java-gradle-plugin"
	//可能是原有的編譯環境，註釋掉，否則報錯
	//id "io.spring.javaformat" version "${javaFormatVersion}"
	id "checkstyle"
}
