value enablePlugins is not a member of sbt.Project
Today I was setting up a couple of projects. One was a simple model library, the next an Akka application, and the last a Play app that started spitting up errors after I had finished setting up the initial project structure.
[info] Loading project definition from /path/project [info] Compiling 1 Scala source to /path/project/target/scala-2.10/sbt-0.13/classes... [error] bad symbolic reference. A signature in Play.class refers to type AutoPlugin [error] in package sbt which is not available. [error] It may be completely missing from the current classpath, or the version on [error] the classpath might be incompatible with the version used when compiling Play.class. [error] /path/project/Build.scala:21: value enablePlugins is not a member of sbt.Project [error] possible cause: maybe a semicolon is missing before `value enablePlugins'? [error] .enablePlugins(play.PlayScala) [error] ^ [error] two errors found [error] (compile:compile) Compilation failed Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? q
I did a little searching only but couldn't find anything that seemed to match my case. After meticulously comparing the few files in the project to the examples on in the documentation, I found the upgrade guide, and noticed that the sbt version was different than what my build.properties file stated.
So I opened up build.properties and noted the version I originally had
and replaced it with the one in the migration docs:
Hopefully this helps anyone else running into similar issues.
