Scala-SBT
首先安装scala插件. 在13+版本中已经默认有SBT插件.
新建一个Project, 选择基于SBT的Scala项目方式创建
下一步选择JDK和SBT, Scala的版本.
点击Finish, 会生成如下图的代码结构图: 其中
build.sbt文件类似maven的pom.xml
在src/main下会创建java, resources, scala三个Sources Root
新建scala object. (或者新建一个scala class, 但是为了在IDEA中运行, 还要在class中新建一个同名的object)
运行方式:
在scala object上右键Run你的Object名字
使用sbt命令运行
hadoop@hadoop:~/IdeaProjects$ cd scala-sbt/
hadoop@hadoop:~/IdeaProjects/scala-sbt$ ls
build.sbt project src target
hadoop@hadoop:~/IdeaProjects/scala-sbt$ sbt
Loading project definition from /home/hadoop/IdeaProjects/scala-sbt/project
Set current project to scala-sbt (in build file:/home/hadoop/IdeaProjects/scala-sbt/)

- 使用IDEA自带的sbt运行
点击SBT Console视图, 点击绿色的运行按钮, 就会自动运行sbt命令
项目依赖的jar包:
Scala-Module
新建一个空的Project: codebase
空的项目里可以新建多个不同语言的module. 比如scala module, 注意这里没有sbt选项!
因为仅仅是scala模块, 只生成一个src目录, 并所以没有sbt生成的那种固定的代码结构
Maven-Module
可以在这个codebase项目中新建maven工程:
1.点击External Libraries, 然后New Module, 不要在已有的module中再new module
2.注意不要勾选Create from archetype, 否则不会自动帮你生成src/main/java等目录.
3.第一步不在已有的module新建module, 所以New Module的parent界面为none
maven的代码结构是src/main/java, src/main/resources, 以及根目录下的pom.xml用来加载第三方jar包
Gradle-Module
http://clojure.iteye.com/blog/2091723
mkdir gradle-demo && cd gradle-demo && vi build.gradle
apply plugin: 'idea'
apply plugin: 'scala'
task "createDirs" << {
sourceSets*.scala.srcDirs*.each { it.mkdirs() }
sourceSets*.resources.srcDirs*.each { it.mkdirs() }
}
repositories{
mavenCentral()
mavenLocal()
}
dependencies{
compile "org.scala-lang:scala-library:2.10.4"
compile "org.scala-lang:scala-compiler:2.10.4"
compile "org.scala-lang:scala-reflect:2.10.4"
testCompile "junit:junit:4.11"
}
task run(type: JavaExec, dependsOn: classes) {
main = 'Main'
classpath sourceSets.main.runtimeClasspath
classpath configurations.runtime
}
gradle createDirs
:createDirs
BUILD SUCCESSFUL
Total time: 4.413 secs
在IDEA中Import Module, 选择刚才创建的目录
Clojure-module
安装IDEA的clojure插件La Clojure.
创建一个clojure-module: clojure-demo
在HelloClojure.clj右键点击Run ‘HelloClojure’，快捷键为: Ctrl+Shift+F10
或者右键点击Start Clojure Console, 快捷键为Ctrl+Shift+D
这个调用的实际上是Clojure的REPL, 和在命令行上执行java -jar clojure.jar是一样的
leiningen
Scala相关的插件有SBT和scala. 其中SBT会创建出样例式的代码结构工程. scala没有. 而La Clojure插件也没有.
clojure的构建工具是: leiningen

下载 https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lei… 脚本放到~/bin下
mv lein.txt lein
chmod 755 lein
第一次执行lein会去下载leiningen.jar包. 后面再次执行时还会下载, 参考lein脚本设置LEIN_JAR就使用已有的jar
vi ~/.bashrc
export LEIN_JAR=/home/hadoop/.lein/self-installs/leiningen-2.5.0-standalone.jar
export PATH=$PATH:/home/hadoop/sh:/home/hadoop/bin
source ~/.bashrc
hadoop@hadoop:~/IdeaProjects/codebase$ lein new clojure-project
Generating a project called clojure-project based on the 'default' template.
The default template is intended for library projects, not applications.
To see other templates (app, plugin, etc), try `lein help new`.
