1.将Tomcat fork到自己仓库并将源码下载到本地

git clone https://github.com/XXX/tomcat.git

2.安装Ant

Tomcat是ant构建的项目，所以需要安装Ant，安装步骤如下：
（1）下载安装包（版本号至少是1.9.10）（注意：官方网站上给出了详细的build步骤，参考链接：https://tomcat.apache.org/tomcat-10.0-doc/building.html）
（2）解压安装包unzip apache-ant-1.10.10-bin.zip
（3）编辑.bash_profile

export ANT_HOME=/Users/sunxi/Documents/application/apache-ant-1.10.10
export PATH=$ANT_HOME/bin:$PATH

（4）source .bash_profile
（5）验证ant安装

sunxi@sunxideMacBook-Pro ~ % ant -version
Apache Ant(TM) version 1.10.10 compiled on April 12 2021

3.编译Tomcat源码

（1）拷贝一份build.properties.default文件并将其重命名为build.properties，修改该文件中的base.path（该路径是用来存放构建Tomcat时下载的依赖包，这里是绝对路径）

base.path=/xxx/application/tomcat-build-libs

（2）将build.xml文件中以下内容注释掉，注释的原因是：因为其会在下载依赖时去获取一个nsis.exe的文件，用来生成tomcat在windows平台的安装程序的。我们这里不需要，所以可以在ant的构建文件build.xml里把它去掉。（这里笔者在分别在注释前后都有测试，在笔者环境中没有任何问题，这里笔者给出一个参考链接：https://mp.weixin.qq.com/s/iK12Qhj8vcfLLFLPCHwIrg）

<antcall target="downloadzip">
	<param name="sourcefile" value="${nsis.loc}"/>
	<param name="destfile" value="${nsis.exe}"/>
	<param name="destdir" value="${nsis.home}/.."/>
	<param name="checksum.enabled" value="${nsis.checksum.enabled}"/>
	<param name="checksum.algorithm" value="${nsis.checksum.algorithm}"/>
	<param name="checksum.value" value="${nsis.checksum.value}"/>
</antcall>

（3）在源码的根目录下执行ant命令编译，命令执行成功后会在屏幕中显示BUILD SUCCESSFUL
笔者在编译过程中出现以下报错，参照链接https://blog.csdn.net/u011109679/article/details/117674702进行了修复，具体
报错信息及解决方法如下：

报错信息

BUILD FAILED
/Users/sunxi/Documents/gitcode/tomcat/build.xml:1040: The following error occurred while executing this line:
/Users/sunxi/Documents/gitcode/tomcat/build.xml:3805: Failed to parse date string 06/15/2021 03:04:19 下午.

解决方法

将源码根目录下的build.xml文件中的<format property="tstamp.file" pattern="MM/dd/yyyy hh:mm:ss aa"/>修改为
<format property="tstamp.file" pattern="123"/>（pattern修改为任意字符串即可）；
将源码根目录下modules/jdbc-pool/build.xml文件中的<format property="tstamp.file" pattern="MM/dd/yyyy hh:mm:ss aa"/>修改为
<format property="tstamp.file" pattern="123"/>

4.将代码导入IDEA

（1）在源码的根目录下执行以下命令

ant ide-intellij

执行完该命令后界面会如下所示：

（2）将代码导入IDEA并在IDEA中配置好ANT_HOME和TOMCAT_BUILD_LIBS，如下图所示：
在这里插入图片描述
（3）在本地创建catalina-home目录并将编译成功后的源码的output目录下的build目录中的所有文件拷贝至catalina-home

（4）在IDEA中配置Tomcat的入口、VM参数，具体如下：

配置项	value
Main class	org.apache.catalina.startup.Bootstrap
VM options	-Dcatalina.home=/Users/sunxi/Documents/application/catalina-home -Duser.language=en -Duser.region=US -Dfile.encoding=UTF-8

5.在IDEA中启动Tomcat

启动方法是运行org.apache.catalina.startup.Bootstrap的main方法，启动完成后打开浏览器输入127.0.0.1:8080后页面显示如下：
