kakfa源代码开发环境搭建过程中的错误处理

2023-08-04 14:18:58

在window上搭建kafka的源代码开发环境，主要参考如下的blog：

http://www.bubuko.com/infodetail-695974.html << Windows平台搭建Kafka源代码开发环境(Eclipse版本) >>

http://*.com/questions/25994163/could-not-resolve-all-dependencies-for-configuration-classpath

但是在国内的网络环境限制, 下载依赖的jar包出现了各种问题，本文将介绍如何修改kafka源代码中的构建文件，避免这些问题：

gradle下载：

https://services.gradle.org/distributions/gradle-2.9-all.zip

GRADLE_HOME

gradlew eclipse
gradle wrapper

der using the daemon: http://gradle.org/docs/2.2.1/userguide/gradle_daemon.html.
FAILURE: Build failed with an exception.
* What went wrong:

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug
option to get more log output.
BUILD FAILED

解决办法：
修改build.gradle
//buildscript {
// repositories {
//    mavenCentral()
// }
// apply from: file('gradle/buildscript.gradle'), to: buildscript
//}
为
buildscript {
     repositories {
    jcenter {
//        url "http://jcenter.bintray.com/"
        maven { url 'http://repo1.maven.org/maven2' }
    }
    apply from: file('gradle/buildscript.gradle'), to: buildscript
}
}

修改
//allprojects {
// apply plugin: 'idea'
// repositories {
//    mavenCentral()
// }
//}
为
allprojects {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
}
}

BUILD FAILED
意思是 [id 'license'] 没有被发现，修改buildscript，添加apply from: file('gradle/buildscript.gradle'), to: buildscript
buildscript {
     repositories {
    jcenter {
//        url "http://jcenter.bintray.com/"
        maven { url 'http://repo1.maven.org/maven2' }
    }
    apply from: file('gradle/buildscript.gradle'), to: buildscript
}
}
然后执行 grade wrapper #BUILD SUCCESSFUL

---------------------------------------------------

D:\源码\kafka-0.8.2.1-src>gradle eclipse

卡在下载 scalatest_2.10/1.9.1/scalatest_2.10-1.9.1-sources.jar 的过程中，死活下载不了，

目前使用的是 http://jcenter.bintray.com/库，改成库 "http://repo1.maven.org/maven2/" 试一下，最后执行成功。

vi build.gradle

修改如下配置：

allprojects {
repositories {
    jcenter {
//        url "http://jcenter.bintray.com/"
        url "http://repo1.maven.org/maven2/"
    }
}
}
scalatest_2.10-1.9.1.jar of core build path is cross-compiled with an incompatible version of Scala (2.10.0). In case this report is mistaken, this check can be disabled in the compiler preference page.     core          Unknown     Scala Version Problem

--------------------------------------------------------------------

D:\源码\kafka-0.8.2.1-src>gradle idea

失败，

解决办法，修改build.gradle

需改如下内容，

修改

//allprojects {
// apply plugin: 'idea'
// repositories {
// mavenCentral()
// }

//}

为，并加上apply plugin: 'idea' ，

allprojects {

repositories {

apply plugin: 'idea'

jcenter {
//        url "http://jcenter.bintray.com/"
        url "http://repo1.maven.org/maven2/"
    }
}

}

------------------------------------------

maven { url 'http://repo1.maven.org/maven2' }
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
}
repositories {
    maven {
        url "http://repo1.maven.org/maven2"
    }

}
