Tomcat8源码下载：

https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.57/src/apache-tomcat-8.5.57-src.tar.gz

导入2019.1 IDEA进行配置：

1. 导入IDEA；
2. 在根目录下新建pom.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

3. 右键Add maven project，使得idea识别出该项目为maven项目，并且下载资源包。
4. 在根目录下新建launch目录，此目录将作为catalina home。
5. 将根目录下的bin/ conf/ logs/ temp/ webapps/ work/ 剪切到launch下，没有则新建。
   
6. 配置运行参数：

org.apache.catalina.startup.Bootstrap

-Dcatalina.home=D:\IdeaProjects\apache-tomcat-8.5.57-src\launch
-Dcatalina.base=D:\IdeaProjects\apache-tomcat-8.5.57-src\launch
-Dfile.encoding=UTF-8
-Duser.region=us
-Duser.language=en

7. 运行即可！！恭喜成功。

问题集锦

• 编译报错java.lang.ClassNotFoundException: listeners.ContextListener，但是还是能运行。

    **删除webapps下的example项目，即可。**
  

• Error:osgi: [apache-tomcat-8.5.57-src] Invalid value for Bundle-Version, @[e-mail] does not match [0-9]{1,9}(.[0-9]{1,9}(.[0-9]{1,9}(.[0-9A-Za-z_-]+)?)?)?

    **@[e-mail]=1.1**
  

• 编译乱码

    **-Duser.region=us
   	-Duser.language=en
   **
  

• TestCookieFilter 报错找不到这个类CookieFilter

   	**删除这个TestCookieFilter类即可**
  

• org.apache.jasper.JasperException: java.lang.NullPointerException

    	**
    	org.apache.catalina.startup.Bootstrap 添加代码块：
    	JasperInitializer initializer =new JasperInitializer();
    	**
