kafka源码阅读环境搭建

1、源码地址

http://archive.apache.org/dist/kafka/0.10.0.0/kafka-0.10.0.0-src.tgz

2、环境准备

centOS

gradle 下载地址 https://services.gradle.org/distributions/gradle-3.1-bin.zip 安装请参考这里。注意要安装3.1版本，如果安装1.1版本可能会出错。

Scala

Java

3、生成idea项目文件

解压kafka-0.10.0.0-src.tgz

进入目录，执行gradle idea

4、问题：

执行gradle idea时，报错

[root@bigdata01 kafka-0.10.0.0-src]# gradle idea
Starting a Gradle Daemon (subsequent builds will be faster)
Building project 'core' with Scala version 2.10.6

FAILURE: Build failed with an exception.

* Where:
Build file '/opt/bigdata/kafka/kafka-0.10.0.0-src/build.gradle' line: 230

* What went wrong:
A problem occurred evaluating root project 'kafka-0.10.0.0-src'.
> Failed to apply plugin [class 'org.gradle.api.plugins.scala.ScalaBasePlugin']
   > No such property: useAnt for class: org.gradle.api.tasks.scala.ScalaCompileOptions

* Try:

BUILD FAILED

解决方法：vim kafka-0.10.0.0-src/build.gradle文件

添加如下行

ScalaCompileOptions.metaClass.daemonServer = true
ScalaCompileOptions.metaClass.fork = true
ScalaCompileOptions.metaClass.useAnt = false
ScalaCompileOptions.metaClass.useCompileDaemon = false

执行gradle idea时，报错

FAILURE: Build failed with an exception.

* Where:
Build file '/opt/bigdata/kafka/kafka-0.10.0.0-src/build.gradle' line: 48

* What went wrong:

我之前安装的是1.1版本的Gradle。换成3.1版本后，问题解决。
