spring-boot编译源码

学习spring-boot源码第一步： 编译源码，搭建环境。

编译环境

  1. ubuntu18.04
  2. JDK1.8
  3. maven 3.5.2

编译过程

如果直接使用：mvn -Dmaven.test.skip=true clean install 安装，大概会遇到下面的错误：

错误原因是： 内存不足。由于spring-boot-project/spring-boot-tools下的spring-boot-gradle-plugin项目造成的，一个比较暴力的解决办法是直接删掉这个项目下的src/test/java，因为暂时也用不到它。删除后再执行：

1
mvn -Dmaven.test.failure.ignore=true -Dmaven.test.skip=true clean install

编译了哪些模块请看附录， 还是很有价值的。

导入项目

idea： file-》open 即可

遇到一些maven问题，稍微修改下即可。主要是maven版本，idea自带的为3.3.9，需要升级：
Properties in parent definition are prohibited

测试项目

运行自带的项目：spring-boot-samples/spring-boot-sample-test/src/main/java/sample/test/SampleTestApplication.java
