kafka源码编译

1.准备环境

1.java环境

java -version

2.scala环境

scala -version

3.gradle环境

gradle -version

4.kafka

这里下载0.11.3，gradle版本也要选择低版本，4.10.2可以编译成功，5.6,6.8都编译失败

2.编译kafka

解压kafka-0.11.0.3-src.tgzF:\resources>cd kafka-0.11.0.3-srcF:\resources\kafka-0.11.0.3-src>gradle idea

1.报错信息1

提示kafka-0.11.0.3-src目录下build.gradle的140行，findbugs有问题

2.报错信息2

提示504行org.scoverage

把 build.gradle 文件29行

classpath 'org.scoverage:gradle-scoverage:2.1.0'

2.1.0修改为2.5.0，再次执行gradle idea

3.报错信息3

再次降低gradle版本，由5.6改为4.10.2，gradle-scoverage:2.5.0修改回来2.1.0
