tomcat 8.5 源码编译 --- maven方式

官方自带的是ant编译、这玩意不太懂 不捣鼓了

解压下载的源码包 目录结构大致如下

java
test
bin
conf
modules
res
target
webapps
build.properties.default
build.xml
BUILDING.txt
CONTRIBUTING.md
KEYS
LICENSE
MERGE.txt
NOTICE
README.md
RELEASE-NOTES
RUNNING.txt

新建一个pom.xml

然后import到eclipse
编译会有错误、删除test目录下的有错误的几个文件就ok
启动的

org.apache.catalina.startup.Bootstrap 的main方法

发现运行的时候也会报错、继续删除
webapps/examples 文件夹

大功告成
