生成Gradle Java应用程序的dockerfile

这是我的build.gradle文件。 在eclipse中,我通过eclipse中的gradle运行docker任务,没有错误,并生成dockerfile和image。 但是当我尝试在项目位置编写ubuntuterminal的gradle build时,出现错误。 我将尝试通过编写gradle distDucker来运行任务以获得项目的gradle distDucker

build.gradle文件:

 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' } 

terminal上的这个错误:

 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. BUILD FAILED Total time: 4.9 secs 

Stacktrace很复杂。 inputgradle build --stacktrace

build.gradle中的第12行: apply plugin: 'docker' docker apply plugin: 'docker'

看起来你正在使用老版本的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find它。
