SBT构建开发环境与代理和仓库配置

SBT构建开发环境

1）安装

安装大体可参考http://www.scala-sbt.org/release/tutorial/zh-cn/Combined+Pages.html 中所示，我的过程如下：

windows环境，下载sbt-0.13.9.zip，解压后到D:/sbt/（不要有空格的路径），然后修改D:/sbt/conf目录下的sbtconfig.txt文件，在最后加入如下几行配置：
-Dsbt.ivy.home=D:/sbt/.ivy2
-Dsbt.global.base=D:/sbt/.sbt
-Dsbt.repository.config=D:/sbt/conf/repo.properties

-Dsbt.log.format=true

##如下为代理的配置包括http与https.
-Dhttp.proxyHost=10.18.11.11
-Dhttp.proxyPort=8080
-Dhttp.proxyUser=xx
-Dhttp.proxyPassword=xx

-Dhttps.proxyHost=10.18.1111
-Dhttps.proxyPort=8080
-Dhttps.proxyUser=xx
-Dhttps.proxyPassword=xx

第一个是设置本地自定义repository路径（如果不设置就是默认的用户目录）。
然后在D:/sbt/conf/目录下新建repo.properties文件，内容为：
[repositories]
  local
  comp-maven:http://mvnrepository.com/artifact/
  store_cn:http://maven.oschina.net/content/groups/public/
  store_mir:http://mirrors.ibiblio.org/maven2/
  store_0:http://maven.net.cn/content/groups/public/
  store_1:http://repo.typesafe.com/typesafe/ivy-releases/
  store_2:http://repo2.maven.org/maven2/

  sbt-releases-repo: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
  sbt-plugins-repo: http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
  maven-central: http://repo1.maven.org/maven2/
请确保一定要增加高亮部分，否则会出现如下错误， 最后把路径D:\sbt\bin 添加到Path中。

D:\work\scala\sbt\bin>sbt.bat

如果使用Idea来开发有关scala sbt项目，那需要在idea里安装scala插件，如下图：

然后在settings里更改两个地方：

第一个是sbt_launch.jar的本地路径。
第二个是VM parameters的设置，加入最后两行就可使用本地ivy库。

这样就完成了sbt与idea scala插件的安装，以后用idea建sbt工程都会用那个本地库。

3）在cmd中，进入项目路径中后，键入sbt，然后就可使用命令（compile，package）就可以将依赖包加到库中，编译，测试，打包等。

4）有关libraryDependencies，格式为：groupID % artifactID % revision，或者groupID %% artifactID % revision，使用后者的话，artifactID将会加上当前scala版本对应的jar的version号，我认为这种方式很容易造成错误。

If you use groupID %% artifactID % revision rather than groupID % artifactID % revision (the difference is the double %% after the groupID), sbt will add your project’s Scala version to the artifact name. This is just a shortcut. You could write this without the %%:

libraryDependencies += "org.scala-tools" % "scala-stm_2.11.1" % "0.3"

Assuming the scalaVersion for your build is 2.11.1, the following is identical (note the double %% after "org.scala-tools"):

libraryDependencies += "org.scala-tools" %% "scala-stm" % "0.3"
