IDEA使用Gradle编译Spring源码

Gradle 运行时的 JVM 参数可以通过 GRADLE_OPTS 或 JAVA_OPTS 来设置.这些参数将会同时生效。 JAVA_OPTS 设置的参数将会同其它 JAVA 应用共享，一个典型的例子是可以在 JAVA_OPTS 中设置代理和 GRADLE_OPTS 设置内存参数。同时这些参数也可以在 gradle 或者 gradlew 脚本文件的开头进行设置。

编译之前

1、cd 进入spring-framework代码目录

2、修改sesstings.gradle 设置阿里云仓库地址

pluginManagement {
	repositories {
		gradlePluginPortal()
		maven { url 'https://maven.aliyun.com/repository/public' }
		maven { url 'https://repo.spring.io/plugins-release' }
	}
}

3、修改build.gradle依然添加阿里云仓库地址

repositories {
			maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
			maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter' }
			mavenCentral()
			maven { url "https://repo.spring.io/libs-spring-framework-build" }
		}

4、修改gradle.properties，调大JVM参数

version=5.3.3-SNAPSHOT
org.gradle.jvmargs=-Xmx2048M
org.gradle.caching=true
org.gradle.parallel=true
kotlin.stdlib.default.dependency=false

5、编译spring-oxm

导入IDEA

1、选择存在的项目资源导入

2、选择spring-framework源码目录

3、选择Gradle项目

4、导入项目参数配置

IDEA Spring源码构建

注意：看发布日志，有些修复了Gradle的问题。

gradle-wrapper.properties，指定gradle的工具包为6.7.1 (Idea 2018.3编译成功，也可以改为6.1试一试，最好环境和配置版本都保持一致)

注意：出现java.lang.NoClassDefFoundError: org/gradle/api/internal/plugins/DefaultConvention 就表示Idea和Gradle版本不兼容。
