Spring-boot 2.3.x源码基于Gradle编译过程详解
spring Boot源码编译
1. git上下拉最新版的spring Boot
下载:git clone git@github.com:spring-projects/spring-boot.git,建议下载release版本,不会出现奇奇怪怪的错误

2.修改下载源,
gradle\wrapper中的配置文件
gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists #distributionUrl=https\://services.gradle.org/distributions/gradle-6.4-bin.zip //这里Gradle换成你自己存放gradle的路径以及gradle的压缩包名 //这里需要注意的是gradle版本问题,尽量高一点儿,就是用了gradle-4.9的版本,导致报错gradle-api plugins问题,还缺包啥的,换了包之后就没问题了 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"
//可能是原有的编译环境,注释掉,否则报错
//id "io.spring.javaformat" version "${javaFormatVersion}"
id "checkstyle"
}

useVersion "${kotlinVersion}"
}
if (requested.id.id == "org.jetbrains.kotlin.plugin.spring") {
useVersion "${kotlinVersion}"
}
}
}
}
2. idea导入
在编译的时候点击取消,配置idea



3.开始编译

至此撒花编译成功!

不过后面还有好长时间的检测,不知道是什么鬼??
