windows下kafka源码阅读环境搭建
[*]工具准备：jdk1.8,scala-2.11.11,gradle-3.1,zookeeper-3.4.5,kafka-0.10.0.1-src.tgz, kafka_2.11-0.10.0.1.tgz
[*]安装jdk
[*]安装scala
[*]搭建zookeeper
[*]kafka源码构建解压kafka-0.10.0.1-src.tgz，命令行进行kafka-0.10.0.1-src，执行gradle idea
注：1)gradle idea，用国外的库构建的下载速度很慢，在进入项目里面，找到build.gradle文件的修改库为阿里镜像库
buildscript {repositories { maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'} }apply from: file('gradle/buildscript.gradle'), to: buildscript
dependencies { // For Apache Rat plugin to ignore non-Git files classpath "org.ajoberstar:grgit:1.5.0" classpath 'com.github.ben-manes:gradle-versions-plugin:0.12.0' classpath 'org.scoverage:gradle-scoverage:2.0.1'}}
allprojects {apply plugin: 'idea'apply plugin: 'eclipse'apply plugin: "jacoco"
allprojects { repositories { maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'} }}2)执行gradle idea时，报错
* What went wrong:A problem occurred evaluating root project 'kafka-0.10.0.1-src'.> Failed to apply plugin > No such property: useAnt for class: org.gradle.api.tasks.scala.ScalaCompileOptions
* Try:Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
解决方法：打开kafka-0.10.0.1-src目录下build.gradle文件添加如下行 view plain copyScalaCompileOptions.metaClass.daemonServer = trueScalaCompileOptions.metaClass.fork = trueScalaCompileOptions.metaClass.useAnt = falseScalaCompileOptions.metaClass.useCompileDaemon = false
7.用intellij idea打开kafka-0.10.0.1-src8.复制log4j.properties文件放到core模块的src/main/scala路径下，这样才能正常的显示日志9.增加scala-sdk10.配置启动参数11.启动项目12.验证解压kafka_2.11-0.10.0.1.tgz文件，命令行进入bin/windows1）创建topicC:\webserver\kafka_2.11-0.10.0.1\bin\windows>kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testMsgCreated topic "testMsg".
控制台日志如下：2）执行生产者命令，产生消息：
3）执行消费者命令，消费消息：问题：ERROR Processor got uncaught exception. (kafka.network.Processor)
java.nio.BufferUnderflowException解决方案：这是客户端的jar包和集群的版本号在小版本不一致导致，保持版本号一致即可。scala-2.11.11,kafka-0.10.0.1-src.tgz, kafka_2.11-0.10.0.1.tgz
