我得到“不是有效的密钥:gen”，用一个干净的sbt 0.13+安装如何修复它？

Question

我想让gen-idea开始工作。我就是这样安装sbt和idea插件的：

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

我正在按照手册安装说明：

$ 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

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 $0`/sbt-launch.jar "$@"

然后，在保存之后：

$ 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，我按照以下指示：

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

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

我输入以下内容：

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]   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.

如何纠正“非有效密钥:gen-idea”的问题？

Answer 1

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)：

[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/)

解决方案是将sbt插件信息放在另一个位置(或设置sbt.global.base属性，如上文所述)：

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