Scala 我得到；不是有效的密钥：gen idea“；，清洁安装sbt 0.13+；如何修复它？

我正试图让

gen idea

发挥作用。这就是我安装

sbt

和

idea

插件的方式：

我按照手册的安装说明进行操作：

$ 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

在

sbt

文件中，我放置了以下内容：

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

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/)


> gen-idea
[error] Not a valid command: gen-idea
[error] Not a valid project ID: gen-idea
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: gen-idea
[error] gen-idea
[error]         ^

然后，保存后：

$ 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

然后我按照以下说明进行操作：

$ 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

我输入以下内容：

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

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/)


> gen-idea
[error] Not a valid command: gen-idea
[error] Not a valid project ID: gen-idea
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: gen-idea
[error] gen-idea
[error]         ^

如何纠正获取“无效密钥：gen idea”的问题？

您使用的是较新版本的sbt，这一点非常清楚（您在输出中得到了这一点）：

解决方案是将sbt插件信息放在另一个地方（或设置

sbt.global.base

属性，如上所述）：

谢谢，顺便问一下，如果我是根据安装说明安装的，为什么我会收到警告？使用自定义默认文件夹0.13而不是默认文件夹是0.13的固有部分吗？因此，sbt 0.13总是会出现这种情况？@Tomer安装说明有点过时，而且。是的，这有点突破性的变化是0.13。
