我得到「不是一個有效的關鍵：gen-idea」，乾淨安裝sbt 0.13+如何解決它？

Question

我試圖讓gen-idea工作。這是我如何安裝sbt和idea插件：

http://www.scala-sbt.org/release/docs/Getting-Started/Setup.html

我正在關注的手動安裝說明：

$ mkdir -p ~/bin 
$ cd ~/bin 
$ wget http://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/0.13.0/sbt-launch.jar 
$ vi sbt 

裏面的sbt文件，我把這個內容：

SBT_OPTS="-Xms512M -Xmx1536M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M" 
java $SBT_OPTS -jar `dirname $0`/sbt-launch.jar "$@" 

然後，保存後：

$ chmod u+x ~/bin/sbt 

./sbt 

$ ./sbt 
Getting org.scala-sbt sbt 0.13.0 ... 
:: retrieving :: org.scala-sbt#boot-app 
    confs: [default] 

. 
. 
. 

$ ./sbt --version 
sbt launcher version 0.13.0 

然後我按照下列指示：

https://github.com/mpeltonen/sbt-idea

$ vi ~/.sbt/plugins/build.sbt 

我進入這個內容：

resolvers += "Sonatype snapshots" at "http://oss.sonatype.org/content/repositories/snapshots/" 

addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.6.0-SNAPSHOT") 

$ cd ~/tmp 
$ ~/bin/sbt 
~/tmp$ ~/bin/sbt 
[warn] The global sbt directory is now versioned and is located at /home/me/.sbt/0.13. 
[warn] You are seeing this warning because there is global configuration in /home/me/.sbt but not in /home/me/.sbt/0.13. 
[warn] The global sbt directory may be changed via the sbt.global.base system property. 
[info] Set current project to tmp (in build file:/home/me/tmp/)

如何糾正得到「不是一個有效的關鍵問題：gen-idea'？

Answer 1

您使用SBT的新版本，這是這個很清楚（你得到了這個輸出）：

[warn] The global sbt directory is now versioned and is located at /home/me/.sbt/0.13. 
[warn] You are seeing this warning because there is global configuration in /home/me/.sbt but not in /home/me/.sbt/0.13. 
[warn] The global sbt directory may be changed via the sbt.global.base system property. 
[info] Set current project to tmp (in build file:/home/me/tmp/) 

解決的辦法是把SBT在另一個地方插件信息（或設置sbt.global.base財產，如上所述）：

cat ~/.sbt/0.13/plugins/build.sbt 
addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.5.1")
