eclipse导入Spring 5.0X源码

1. 版本信息
eclipse Version: 2018-12 (4.10.0)
gradle-4.9
JDK 1.8

2. gradle-4.9
下载链接：(https://services.gradle.org/distributions/)

gadle下载时候有三个包，gradle-src为gralde源码，gradle-bin为安装包，gradle-all为源码加安装包，我们这里只需下载安装包就可以了。

gradle安装步骤

1. 将下载的gradle-4.9解压
2. 配置gradle环境变量

配置的两种方式：
1.新建用户变量 -------> 变量名（GRADLE_HOME） 变量值（自己解压gradle的文件夹路径） ------> 将新建的用户变量添加到系统变量path的末尾增加：;%GRADLE_HOME%/bin;

2.将gradle的解压路径直接配置在path里面

注：本人是选择的第二种方式

配置完成以后验证：win+r，输入cmd进入dos界面， 键入命令gradle -v

3. 下载Spring 5.0X源码
下载链接：(https://github.com/spring-projects/spring-framework)
注：没有账号的同学自己注册一个哟！！！

  选择5.0X版本

然后下载一个压缩包

4. 导入eclipse过程
1）将Spring 5.0X压缩包解压
2）找到import-into-eclipse.bat

3）运行import-into-eclipse.bat。根据界面提示操作，运行成功出现BUILD SUCCESSFUL（如果失败，根据提示排查，目前这一步基本没有遇到问题）
4）执行命令（因为第一次导入的时候出现导入的Spring丢失了一些架包的情况，所以后面吸取教训就执行一些命令。建议执行，如果能确保自己前面步骤一定不会出现架包丢失，也可以不执行）
在Spring 源码的解压目录下执行：
– gradle objenesisRepackJar
– gradle cglibRepackJar

注：
执行命令的时候可能会报错提示：spring-framework-5.0.x\spring-beans\spring-beans.gradle 第二十八行存在错误。
解决方法：注释这一行

5）eclipse 安装Groovy
Help -----> Eclipse Maker ------>搜索Groovy

安装Groovy，注意Groovy的版本需要指向2.5
6）安装AspectJ
Help选项，选择Install New Software

AspectJ ： (http://download.eclipse.org/tools/ajdt/43/update)

7）导入Spring
右键import

8）检查报错
如果有项目报错，检查是不是Groovy版本问题。

如果是2.4的版本，就指向2.5就能解决报错。

5. 测试
