[Scala] Scala 开发环境搭建

Scala 开发环境搭建
-------------------
下载
1. 下载JDK 6+
2. 下载Scala
3. 下载SBT
4. 下载ScalaIDE

配置
JAVA_HOME CLASSPATH
SCALA_HOME
SBT_HOME
PATH

创建工程
~/workspace>mkdir project-template
~/workspace/project-template>cd project-template
~/workspace/project-template>echo > build.sbt

build.sbt

import AssemblyKeys._   // 部署打包插件
assemblySettings

name := "project-template"  // 类似MAVEN, 项目名称 , 版本, SCALA版本

version := "1.0"

scalaVersion := "2.11.2"

EclipseKeys.createSrc := EclipseCreateSrc.Default + EclipseCreateSrc.Resource // 创建资源文件夹

// 依赖包
libraryDependencies ++= Seq(
	"org.json4s" %% "json4s-native" % "3.2.11", // 组, 签名, 版本
    "org.json4s" %% "json4s-jackson" % "3.2.11"
)

// 仓库
resolvers ++= Seq(
  "Maven Repository"     at "http://repo.maven.apache.org/maven2",
  "Apache Repository"    at "https://repository.apache.org/content/repositories/releases",
  "JBoss Repository"     at "https://repository.jboss.org/nexus/content/repositories/releases/",
  "MQTT Repository"	at "https://repo.eclipse.org/content/repositories/paho-releases/",
  "Cloudera Repository"  at "http://repository.cloudera.com/artifactory/cloudera-repos/",
  "sonatype-staging"     at "https://oss.sonatype.org/service/local/staging/deploy/maven2/",
  Resolver.mavenLocal
) 

~/workspace/project-template>mkdir project
~/workspace/project-template>cd project
~/workspace/project-template/project>echo > plugins.sbt

plugins.sbt

resolvers += Resolver.url("artifactory", url("http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases"))(Resolver.ivyStylePatterns)

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.5.0")

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")
 

~/workspace/project-template/project>cd ..
~/workspace/project-template>sbt
>eclipse
>assembly

添加依赖,修改build.sbt | libraryDependencies ,然后重新运行 eclipse 命令.

运行:

sbt run

测试打包

java -jar ~/worksapce/project-template/target/scala-2.11/project-template-assembly-1.0.jar

或者:

java -cp ~/worksapce/project-template/target/scala-2.11/project-template-assembly-1.0.jar [b]Hello[/b]
