kafka 0.10.0.1 源码编译 之感
查看视频 和 网上的文档，下载了对应的版本，但是编译一直有问题。版本如下：
kakfa版本 ：0.10.0.1
scalan：2.10.6
gradle：3.1
根据提示，不断的修正 版本， 和 修改 build.gradle 和 gradle.script 配置. Gradle 从 3.1 到 7.1，最后到 2.13.

FAILURE: Build failed with an exception.
* Where:
Script '/Users/fred-zhang/Documents/tool/kafka-0.10.0.1-src/gradle/buildscript.gradle' line: 21
* What went wrong:
A problem occurred evaluating script.
> No such property: allowInsecureProtocol for class: org.gradle.api.internal.artifacts.repositories.DefaultMavenArtifactRepository_Decorated
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
发现 版本的不同，gradle 的实现会些不同。
最终 参照 build.gradle中的 gradleVersion =2.13， 又更新了 gradle 的版本
执行 成功了！！！

BUILD SUCCESSFUL
中间断断续续花了 3-4个小时，一直在报错，查找，排错。
版本问题，还是 回归 源码的配置。
源码编译感觉算技术人基本的一项技能，但是 往往很多时候完成不了。
别人也许可以编译，但是 经过时间的变迁，到你也就就行不通了。
