idea配置scala開發環境

1、建立scala項目，報錯。

搜尋：sbt設定MaxPermSize

原因：

（2）https://www.douban.com/note/311383726/

參考解決方法：

解決步驟：

（1）下載下傳sbt1.1.6

（2）進入conf檔案夾，修改sbtconfig.txt（注意配置的路徑關聯）：

# Set the java args to high

-Xmx1024M

-XX:MaxPermSize=m

-XX:ReservedCodeCacheSize=m

# Set the extra SBT options

-Dsbt.log.format=true
-Dsbt.boot.directory=F:/sbt-./data/.sbt/boot
-Dsbt.global.base=F:/sbt-./data/.sbt
-Dsbt.ivy.home=F:/sbt-./data/.ivy2
-Dsbt.repository.config=F:/sbt-./conf/repo.properties

           

（3）在conf中建立repo.properties：

[repositories]
  local
  aliyun: http://maven.aliyun.com/nexus/content/groups/public/
  typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
  sonatype-oss-releases
  maven-central
  sonatype-oss-snapshots
           

（4）打開cmd，輸入sbt，如果出現類似下面的結果則表明安裝成功：

C:\Users\PetterChen>sbt

“C:\Users\PetterChen.sbt\preloaded\org.scala-sbt\sbt\”1.0.3”\jars\sbt.jar”

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

[info] Loading project definition from C:\Users\PetterChen\project

[info] Set current project to petterchen (in build file:/C:/Users/PetterChen/)

[info] sbt server started at 127.0.0.1:4729

sbt:petterchen>

（5）最後在idea配置sbt的sbt-launch.jar路徑。
