1. 下载源码

用git克隆到本地

git clone https://github.com/apache/zookeeper.git

查找对应某个版本的标签，假设是 3.5.9 版本，则基于该版本创建一个本地分支

# 查找对应某个版本的标签
git tag | grep 3.5.9
## release-3.5.9
## release-3.5.9-rc0
## release-3.5.9-rc1
## release-3.5.9-rc2

# 基于标签创建本地分支
git branch myloc-release-3.5.9 release-3.5.9

# 切换到该分支
git checkout myloc-release-3.5.9
## Switched to branch 'myloc-release-3.5.9'

2. 准备更高版本的JDK和Maven环境

Java 8

打开 Zookeeper 仓库根目录下的 README.md 文件，查看其中内容，可能会明确地告知用户需要什么版本的 JDK，例如：

## Java 8 u211 或以上版本

If you are going to compile with Java 1.8, you should use a
recent release at u211 or above.

windows 系统用户可以考虑用 OpenJdk 的发行版 Azul JDKs代替 Oracle JDKs

Maven 3.6.3

Maven 3.6.3 这是我测试过程中稳定的版本，而当时用 InteliJ Idea 本身的 Maven 3 还是有些小问题，故在此特意提及。

3. 用IDEA打开项目进行编译和启动

3.1. 设置maven版本

File > Setting... > Build,Execution,Deployment > Build Tools > Maven

在此设置 Maven home path 自定义选择外部安装的新版本 maven 3.6.3

3.2. 设置JDK版本为1.8

第一件事，设置项目jdk版本：File > Project Structure... > Project Settings > Project

SDK 在选项中选择 1.8 版本

更改项目jdk版本为1.8

3.3. 切换 Maven profiles 选项到 java-build

Zookeeper3.5.9 在 IDEA 的 Maven 界面有以下几个profiles选项：

full-build，这个是包含了zookeeper-contrib模块的，该模块是指多个可选的附加组件，该zookeeper-contrib模块仅限在GNU/Linux系统支持开发和生产，而在windows系统是不支持，所以当我们在windows系统编译源码时不建议选择该profiles选项。
```
<profile>
  <id>full-build</id>
  <modules>
    <module>zookeeper-contrib</module>
  </modules>
</profile>
```

java-build，这个是默认激活的选项，特意用注释提示我们排除了 contrib 模块

<profile>
  <!-- Excluds contrib -->
  <id>java-build</id>
  <activation>
    <activeByDefault>true</activeByDefault>
  </activation>
</profile>

m2e，这个是指 “Maven Integration for Eclipse” (又名m2e)的环境所准备的，而我们并非使用 Eclipse，而是用的 InteliJ IDEA，所以这个选项也不建议选择。从 <activation> 标签可以看到是通过设置 m2e.version 属性来激活的，所以用IDEA默认情况下是不用担心激活该选项的
```
<profile>
  <id>m2e</id>
  <activation>
    <property>
      <name>m2e.version</name>
    </property>
  </activation>
  <properties>
    <maven.compiler.release>8</maven.compiler.release>
  </properties>
</profile>
```

jdk-release-flag，这个是指当JDK版本为9及以上时应该激活的选项

<profile>
  <id>jdk-release-flag</id>
  <activation>
    <jdk>[9,)</jdk>
  </activation>
  <properties>
    <maven.compiler.release>8</maven.compiler.release>
  </properties>
</profile>

apache-release：这个是指最终发布的选项，在执行 mvn release:perform 时启用 <releaseProfiles> profiles

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-release-plugin</artifactId>
 <version>2.5.3</version>
 <configuration>
   <releaseProfiles>apache-release</releaseProfiles>
   <arguments>-Dmaven.test.skip.exec ${arguments}</arguments>
 </configuration>
</plugin>

虽然我们在刚打开项目的时候就更改了项目jdk版本，但是maven并不会实时更新激活的profiles选项，所以为谨慎起见，需要手动设置 Maven profiles 选项为 java-build：

在这里插入图片描述

3.4. 执行 Ant build 生成和编译Java文件

安装 IDEA 的 Ant 插件：File > Settings... > Plugins

调出 IDEA 的 ant build 界面，如果没有，请依次点击菜单：View > Tool Windows > Ant

在这里插入图片描述

然后找到项目根目录下的 build.xml 文件，并右键点击它唤出菜单，选择 Add as Ant Build File。

打开 Ant 界面的 Properties 属性设置，确认设置正确的 jdk：Run under JDK:，保持与之前项目jdk一致（JDK 1.8）。同时也可以将 IDEA 默认的Ant自定义指定为其他已经安装的Ant。

在这里插入图片描述

3.4.1. 执行`ant build-generated`而非`ant eclipse`

网上很多文章都要求执行 ant eclipse 任务，但实际上其本质只是生成一些 .eclipse、.project 之类的文件和目录罢了，关键的其实是其依赖的其他任务。

这样的话，我们是用 InteliJ Idea 打开的项目，eclipse的项目文件就没有作用了，再执行这个任务生成一些没有用的文件就显得有不优雅了，既然关键的不是 eclipse 任务本身，而是其依赖，那我们就可以仅执行我们需要的依赖任务即可，恰好，根据对 eclipse 任务的依赖关系梳理，找到了一个完美的依赖任务，其几乎也依赖所有除 eclipse 之外的需要的任务，那不就巧了，它就是：

ant build-generated

笔记：ant eclipse 任务的依赖关系梳理过程如下

在正式执行 eclipse 任务之前会先执行其依赖的任务：

ant-eclipse-download：下载 Ant-Eclipse，它是 Java 构建工具 Ant 生成 Eclipse 项目的任务，只需轻松导入和使用即可。Ant 构建脚本用作配置生成项目所基于的源代码和库的中心位置。
init：初始化操作，包括创建新的目录和设置时间戳格式，创建的目录包括：

${basedir}/build/classes
${basedir}/build/lib
${basedir}/build/package/lib
${basedir}/build/test/lib

ivy-download：下载 Apache Ivy™ ，它是一个流行的依赖管理器，专注于灵活性和简单性。
ivy-taskdef：结合项目命名空间中的 antlib 定义，它将从 Ant 库或本地目录加载 Ivy 类。
ivy-init：使用 ${basedir}/ivysettings.xml 文件配置 Ivy
ivy-retrieve：该任务将已解析的依赖项复制到文件系统中所需的任何位置
ivy-retrieve-javacc：初始化目录${basedir}/build/javacc/lib，并执行一次ivy:retrieve
generate_jute_parser：生产 jute 解析器
初始化目录${basedir}/build/jute_compiler/org/apache/jute/compiler/generated；
执行一次ivy:artifactproperty，根据之前解析过的依赖包的包名（解析包名根据 <ivy:retrieve> 标签的 pattern=${ivy.lib}/[artifact]-[revision].[ext] 属性），生成一批以 [artifact].revision 格式命名的属性，并将依赖包的 [revision] 赋值给对应包名的属性。例如slf4j-api.revision=1.7.25、commons-lang.revision=2.6和javacc.revision=5.0等等。
执行一次move同位移动来实现文件重命名，将带版本号的 ${basedir}/build/javacc/lib/javacc-${javacc.revision}.jar重命名为没有版本号的${basedir}/build/javacc/lib/javacc.jar
执行一次javacc编译${basedir}/zookeeper-jute/src/main/java/org/apache/jute/compiler/generated/rcc.jj为 java 类并输出到目录 ${basedir}/build/jute_compiler/org/apache/jute/compiler/generated/

jute：用javac编译${basedir}/zookeeper-jute/src/main/java和${basedir}/build/jute_compiler两处源文件为class文件并输出到目录${basedir}/build/classes
compile_jute_uptodate：比较源文件与目标文件时间戳，如果目标文件比源文件更新，则设置属性juteBuild.notRequired=true，该属性用于任务compile_jute的执行条件，只有在它为 false 时才会执行compile_jute任务。
compile_jute：生成一些java类
创建新目录：${basedir}/zookeeper-jute/target/main/java
创建新目录：${basedir}/zookeeper-client/zookeeper-client-c/generated
执行java代码：org.apache.jute.compiler.generated.Rcc，该代码的作用就是编译位于 ${basedir}/zookeeper-jute/src/main/resources/zookeeper.jute 文件内容中的java代码，生成相应的类。包含：
org.apache.zookeeper.data.*
org.apache.zookeeper.proto.*
org.apache.zookeeper.server.quorum.*
org.apache.zookeeper.server.persistence.*
org.apache.zookeeper.txn.*

ver-gen：执行 javac 编译目录为 ${basedir}/zookeeper-server/src/main/java 下的java类，并将产出class文件输出到 ${basedir}/build/classes 目录
git-revision：
创建新目录${basedir}/.revision
判断如果是 windows 操作系统，则设置属性：shell.name=cmd、revision.cmd.line=/c ${basedir}/zookeeper-server/src/main/resources\lastRevision.bat
执行命令：经过人工拼接最终执行的是 cmd /c ${basedir}/zookeeper-server/src/main/resources\lastRevision.bat ${basedir}/.revision/revision.properties （注意：${basedir}是项目根目录，请读者自行脑中替换），所以是执行了一个windows批命令脚本。该脚本会收集当前git仓库的最后一次提交的hash值，并输出到一个 revision.properties 文件中。
将上一个命令输出的 revision.properties 导入到属性集中，其中只有一个属性：lastRevision

version-info：
创建目录${basedir}/zookeeper-jute/target/main/java
执行java代码org.apache.zookeeper.version.util.VerGen，其main()函数参数有三个分别为{3.5.9-SNAPSHOT,83df9301aa5c2a5d284a9940177808c01bc35cef,03/10/2024 00:00:00}，创建一个 org.apache.zookeeper.version.Info.java 文件，该文件记录了一下版本信息。

process-template：将目录${basedir}/zookeeper-client/zookeeper-client-c中的configure.ac.in和include/zookeeper_version.h.in文件复制到同目录并且重命名删除它们的.in后缀。
build-generated：执行 javac 命令编译目录 ${basedir}/zookeeper-jute/target/main/java 下的所有java文件并将产出 class 文件输出到目录 ${basedir}/build/classes
ivy-retrieve-test：测试执行 ivy:retrieve
eclipse：在执行完上面所有 ant 任务之后，才执行最后的这个 eclipse 任务

3.4.2. 对比构建前后项目多了什么

在这里插入图片描述

3.5. maven compile

在 Idea maven 界面执行 compile 目标，如下图所示。

在这里插入图片描述
如果严格按照以上步骤的话，没有意外的会编译成功：

main:

3.6. 准备一个zoo.cfg配置文件

进入目录 ${basedir}/conf/，在同目录复制一个 zoo_sample.cfg 文件并重命名为 zoo.cfg。

打开并且编辑，增加两个属性：

# windows系统下的绝对路径，该目录用于存储zookeeper数据
dataDir=F:\\privateBox\\kafkaCodeReadProject\\zookeeper\\tmp\\zookeeper
# 修改服务端口，避开常用的8080
admin.serverPort=8083

这个配置文件是执行 java 命令时需要作为参数用的，例如：

java org.apache.zookeeper.server.quorum.QuorumPeerMain F:\privateBox\kafkaCodeReadProject\zookeeper\conf\zoo.cfg

3.7. 配置classpath

由于 ant build 生成和编译的文件，大部分都放在了 ${basedir}/build/目录下，所以单独构建 zookeeper-server 模块时会找不到一些由 zookeeper-jute 模块生成的一些类。例如：org.apache.zookeeper.data.ACL、org.apache.zookeeper.data.Stat以及更多

为了让zookeeper-server能接触的到这些类，需要将这些目录加到它的 classpath 里面。

具体操作方法如下：

依次点击菜单：File > Project structure... >

在这里插入图片描述
增加两个目录即可：

${basedir}/build/classes
${basedir}/conf

注意：目录 ${basedir}/conf 里面没有 class 文件，所以 idea 询问你选择的是该目录中的什么类型文件，选择 Classes 即可

配置完成之后，会发现，编辑器里也不会出现org.apache.zookeeper.data.ACL、org.apache.zookeeper.data.Stat等类红色警告，build project 的时候也不会提示找不到该类等错误了。

3.8. 启动 QuorumPeerMain

在 ${basedir}/zookeeper-server 模块目录下找到 org.apache.zookeeper.server.quorum.QuorumPeerMain 类。
右键选择 Modify Run Configuration... 开启设置启动参数配置
jdk选择和项目保持一致，idea会默认选择自带的jdk，建议手动更改为保持项目和ant同一个jdk。
Program arguments 增加内容： ${basedir}\conf\zoo.cfg（请自行替换${basedir}以确保输入一个绝对路径）

然后启动就可以了

查看 InteliJ Idea 启动时的控制台输出的 java 命令内容是什么：

4. 在命令行 cmd 中编译和启动

在完成准备一个zoo.cfg配置文件步骤后，尝试在项目根目录打开 cmd 直接执行 cmd /k bin\zkServer.cmd 脚本启动服务，会直接报错，日志如下所示：

F:\privateBox\kafkaCodeReadProject\zookeeper>cmd /k bin\zkServer.cmd

F:\privateBox\kafkaCodeReadProject\zookeeper>call "C:\Program Files\Java\zulu8.76.0.17-ca-jdk8.0.402-win_x64"\bin\java "-Dzookeeper.log.dir=F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\logs" "-Dzookeeper.log.file=zookeeper-Kitman-server-DESKTOP-S0UTLJU.log" "-XX:+HeapDumpOnOutOfMemoryError" "-XX:OnOutOfMemoryError=cmd /c taskkill /pid %%p /t /f" -cp "F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\build\classes;F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\build\lib\*;F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\*;F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\lib\*;F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\conf" org.apache.zookeeper.server.quorum.QuorumPeerMain "F:\privateBox\kafkaCodeReadProject\zookeeper\bin\..\conf\zoo.cfg"
错误: 找不到或无法加载主类 org.apache.zookeeper.server.quorum.QuorumPeerMain

F:\privateBox\kafkaCodeReadProject\zookeeper>endlocal

无法加载某某类肯定是 classpath 中没有包含该类导致的，说明源码还没有编译完成，至少没有编译这个类到 classpath 包含的目录中，所以在找不到。

通过观察命令当中的 -cp 参数研究其 classpath 明确包含有以下目录：

${basedir}\build\classes
${basedir}\build\lib\*
${basedir}\*
${basedir}\lib\*
${basedir}\conf

也就是说，以上这些目录中，没有编译过的 org.apache.zookeeper.server.quorum.QuorumPeerMain 主类，说明我们还没有完成编译工作。

4.1. 安装 Ant

根据 zookeeper 项目根目录下的 README_packaging.txt 文件中的内容提示，ant 版本建议在 1.9.4 以上。

我们直接到官网下载一个最新的：

在官方下载页面下载一个当前最新版本的二进制包 apache-ant-1.10.14-bin.zip。

注意！Ant 官方提供二进制包下载以及源码包下载，如果下载了源码包还要再次进行编译构建才能真正应用，所以建议直接下载二进制包方便直接配置应用。

解压缩二进制包，将解压缩后 bin 的父目录，添加到环境配置中，命名为ANT_HOME，并添加 %ANT_HOME%/bin/ 到 Path 中。

在新打开的 cmd 中执行 ant -version 验证安装成功。

4.2. 使用 Ant 编译

注意，我们这里不需要制定执行的 ant 任务，就直接执行一个：

ant

查看 build.xml ，发现其中是给项目配置了默认ant任务为 jar 的：

<project name="ZooKeeper" default="jar" 
xmlns:ivy="antlib:org.apache.ivy.ant"
xmlns:artifact="antlib:org.apache.maven.artifact.ant"
xmlns:maven="antlib:org.apache.maven.artifact.ant"
xmlns:cs="antlib:com.puppycrawl.tools.checkstyle.ant">

有的读者可能会问：

为什么不是跟 Idea 打开项目时执行的 ant build-generated 一样呢？

从两个方面来回答：

其实 Idea 也可以用不选择某个任务来执行从而让它执行默认的 ant jar ，但是对于 Idea 环境来说，前者已经足够，ant jar会生成更多的内容，比如会把 zookeeper-server 模块整个编译到 ${basedir}/build/classes里，那这样的话，和 mvn compile 编译到模块 target/classes 目录重复，而观察 InteliJ Idea 启动zookeeper的java命令内容中的classpath，它是同时包含这两个目录的，一旦出现重复，而没有在更新代码之后及时保持两个目录下的编译结果一致，可能会出现不可预知的问题。
对于 zkServer.cmd 脚本只包含 ${basedir}/build/classes 而不包含模块 target/classes 的 classpath 来说，ant build-generated 是不够用的，因为它不会编译 zookeeper-server 模块，会导致脚本找不到主类。

以下记录执行 ant 命令（等效 ant jar）的日志：

4.3. 准备一个zoo.cfg配置文件

进入目录 ${basedir}/conf/，在同目录复制一个 zoo_sample.cfg 文件并重命名为 zoo.cfg。

打开并且编辑，增加两个属性：

# windows系统下的绝对路径，该目录用于存储zookeeper数据
dataDir=F:\\privateBox\\kafkaCodeReadProject\\zookeeper\\tmp\\zookeeper
# 修改服务端口，避开常用的8080
admin.serverPort=8083

这个配置文件是执行 java 命令时需要作为参数用的，例如：

java org.apache.zookeeper.server.quorum.QuorumPeerMain F:\privateBox\kafkaCodeReadProject\zookeeper\conf\zoo.cfg
