windows下使用 intellij idea 编译 kafka 源码环境

windows下使用 intellij idea 编译 kafka 源码环境

1. 从 github 网站，git clone kafka 源码

2. -安装好 gradle，scala

2.1 从 dependencievnIfXs.gradle 文件中找到 gradle 的版本，然后-指定版本，并配置好 GRADLE_HOME 环境变量

3. 进入 kafka 项目目录，依次执行 gradle wrapper，gradle idea，gradle build --exclude-task test

4. 将工程导入到 idea

4.1 启动主类 kafka.Kafka

4.2 program arguments：config/server.properties

4.3 把 config 目录下的 log4j.properties 拷贝到 core/src/main/resources 目录

4.4 File -> Project Structure -> Modules

5. 启动程序

然而，大部分情况下，日志不会打印出来，配置一下 core 模块的 log4j 依赖

找到 build.gradle 文件中的 project(':core')，修改对应的 log4j 依赖，然后重新执行  gradle idea，重新导入 idea 中

project(':core') {

println "Building project 'core' with Scala version ${versions.scala}"

apply plugin: 'scala'

// scaladoc generation is configured at the sub-module level with an artifacts

// block (cf. see streams-scala). If scaladoc generation is invoked explicitly

// for the `core` module, this ensures the generated jar doesn't include scaladoc

http://// files since the `core` module doesn't include public APIs.

scaladoc {

enabled = false

}

if (userEnableTestCoverage)

apply plugin: "org.scoverage"

archivesBaseName = "kafka_${versions.baseScala}"

dependencies {

compile project(':clients')

compile project(':metadata')

compile project(':raft')

compile libs.argparse4j

compile libs.jacksonDatabind

compile libs.jacksonModuleScala

compile libs.jacksonDataformatCsv

compile libs.jacksonJDK8Datatypes

compile libs.joptSimple

compile libs.metrics

compile libs.scalaCollectionCompat

compile libs.scalajava8Compat

compile libs.scalaLibrary

// only needed transitively, but set it explicitly to ensure it has the same version as scala-library

compile libs.scalaReflect

compile libs.scalaLogging

compile libs.slf4jApi

compile libs.slf4jlog4j

compile libs.log4j

compile(libs.zookeeper) {

// exclude module: 'slf4j-log4j12'

// exclude module: 'log4j'

}

// ZooKeeperMain depends on commons-cli but declares the dependency as `provided`

compile libs.commonsCli

compileOnly libs.log4j

testCompile project(':clients').sourceSets.test.output

testCompile libs.bcpkix

testCompile libs.mockitoCore

testCompile libs.easymock

testCompile(libs.apacheda) {

exclude group: 'xml-apis', module: 'xml-apis'

// `mina-core` is a transitive dependency for `apacheds` and `apacheda`.

// It is safer to use from `apacheds` since that is the implementation.

exclude module: 'mina-core'

}

testCompile libs.apachedsCoreApi

testCompile libs.apachedsInterceptorKerberos

testCompile libs.apachedsProtocolShared

testCompile libs.apachedsProtocolKerberos

testCompile libs.apachedsProtocolLdap

testCompile libs.apachedsLdifPartition

testCompile libs.apachedsMavibotPartition

testCompile libs.apachedsJdbmPartition

testCompile libs.junitJupiter

testCompile libs.slf4jlog4j

testCompile(libs.jfreechart) {

exclude group: 'junit', module: 'junit'

}

}

目标就是把下图的 log4j 依赖配置好。
