【SBT構建scala項目】

1、環境準備

scala:http://www.scala-lang.org/

echo $SCALA_HOME

/Users/..../Documents/software/scala-2.11.7

sbt:http://www.scala-sbt.org/

$brew list sbt

/usr/local/Cellar/sbt/0.13.9/bin/sbt

sbt eclipse:https://github.com/typesafehub/sbteclipse

sbt assembly:https://github.com/sbt/sbt-assembly

2、sbt生成scala eclipse項目

2.1 添加sbt eclipse插件

$ ls
simple-sbt

$ pwd
/Users/.../Documents/workspace-scala2

$ tree .
.
└── simple-sbt
    ├── build.sbt
    └── project
        └── plugins.sbt

2 directories, 2 files

plugins.sbt文件內添加插件
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.4.0")

$cd simple-sbt
$sbt eclipse

$ ll
total 16
drwxr-xr-x  8 ...  staff  272 Dec 27 10:52 .
drwxr-xr-x  3 ...  staff  102 Dec 27 10:48 ..

drwxr-xr-x  4 ...  staff  136 Dec 27 10:52 target
===> 生成了eclipse的 .classpath 和 .project目錄

$tree -L 2

└── target

    └── streams

9 directories, 2 files
==> 發現沒有resources目錄
==> 在build.sbt裏面添加
EclipseKeys.createSrc := EclipseCreateSrc.Default + EclipseCreateSrc.Resource

$sbt eclipse

$ tree -L 3

導入到eclipse中。

3、開發與部署

3.1 添加依賴

在build.sbt中添加依賴，能夠再mvnrepository中查找依賴

name := "simple_sbt"

version := "1.0"

scalaVersion := "2.10.3"

EclipseKeys.createSrc := EclipseCreateSrc.Default + EclipseCreateSrc.Resource

libraryDependencies ++= Seq(  
    "org.json4s" %% "json4s-native" % "3.2.10",  
    "org.json4s" %% "json4s-jackson" % "3.2.10"
)

resolvers ++= Seq(  
    // HTTPS is unavailable for Maven Central  
    "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/",  
    // For Sonatype publishing  
    // "sonatype-snapshots"   at "https://oss.sonatype.org/content/repositories/snapshots",  
    // "sonatype-staging"     at "https://oss.sonatype.org/service/local/staging/deploy/maven2/",  
    // also check the local Maven repository ~/.m2 
    Resolver.mavenLocal
)

執行sbt update會下載依賴
再執行sbt eclipse
