生成gradle java应用程序的dockerfile

Question

This is my build.gradle file. In eclipse, I run docker task via gradle in eclipse, there is no error and it generates dockerfile and image. But when I try to write gradle build in ubuntu terminal at project location, I get an error. I will try to run task to get dockerfile of project later by writing gradle distDucker .

build.gradle file:

buildscript {
repositories {
mavenCentral()
}
 dependencies {
  classpath "se.transmode.gradle:gradle-docker:1.2"
}
}

apply plugin: 'java'
apply plugin: 'application'
apply plugin: 'docker'
apply plugin: 'eclipse'

repositories {
mavenCentral()
}

sourceCompatibility = 1.8

mainClassName = 'kafka.MyProducer'

applicationDefaultJvmArgs = ['-Xmx1g',
                         '-Xms1g']

dependencies {
compile group: 'org.apache.kafka', name: 'kafka_2.11',version: '0.10.0.0'    
 }

task copyConf(type: Copy) {
from System.getProperty('user.dir') + "/conf"
into "$buildDir/conf"
}

task createConf {
def conf = file("$buildDir/conf")
outputs.dir conf
doLast {
    conf.mkdirs()
    copyConf.execute()
}
}

distributions {
main {
    contents {
        from(createConf) { into "/conf" }
    }
}
}

docker {
baseImage = 'brscrt/java-8'
maintainer = 'Baris Cirit "brscrt@gmail.com"'
}

distDocker {
tag = 'brscrt/kafkaproducer'
  version = 'latest'

push = project.hasProperty('push') ? project.property('push') : false
} 


task wrapper(type: Wrapper) { gradleVersion = '2.14' }

This error on terminal:

baris@brscrt:~/workspace/KafkaProducer_Gr$ gradle build

FAILURE: Build failed with an exception.

* Where:
Build file '/home/baris/workspace/KafkaProducer_Gr/build.gradle' line: 12

* What went wrong:
A problem occurred evaluating root project 'KafkaProducer_Gr'.
    > Could not create task of type 'DockerTask'.

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

Stacktrace is complicated. After typed gradle build --stacktrace :

baris@brscrt:~/workspace/KafkaProducer_Gr$ gradle build --stacktrace

FAILURE: Build failed with an exception.

Build file '/home/baris/workspace/KafkaProducer_Gr/build.gradle' line: 12

看起来你使用的是旧版本的gradle / groovy，因为org.codehaus.groovy.runtime.typehandling.ShortTypeHandling是在groovy 2.3中引入的，根据堆栈跟踪，类加载器在尝试应用docker插件时无法找到它。
