Error on scalatest compilation in IDEA

Question

I am trying to compile Scala project which contains scalatest. It compiles normal on sbt

sbt
> compile
> test:compile

, but when I am trying to build it with IDEA, it shows the following error:

Error:(37, 11) exception during macro expansion: 
java.lang.NoSuchMethodError: org.scalactic.BooleanMacro.genMacro(Lscala/reflect/api/Exprs$Expr;Ljava/lang/String;Lscala/reflect/api/Exprs$Expr;)Lscala/reflect/api/Exprs$Expr;
at org.scalatest.AssertionsMacro$.assert(AssertionsMacro.scala:34)
assert((ElementMeasures.baseElementDistance(mEl1, mEl2) - 0.33333).abs < 0.001)
      ^

for each assert function in test.

build.sbt file contains following:

name := "ner-scala"
organization := "ml.generall"
version := "1.0-SNAPSHOT"
scalaVersion := "2.11.8"
libraryDependencies += "org.scalactic" %% "scalactic" % "3.0.0"
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.0" % "test"
...

Answer 1

It may also mean that you have more than one versions of scalatest registered. I came into pretty same issue with compile-time error on assert

Answer 2

I just ran into the same problem and as Alexey described (he should get the upvote but I don't have enough reputation to upvote or comment - thank you Alexey), it seems that it was caused by having multiple versions of scalatest in my project. I was able to fix it by specifically excluding the older scalatest from the library that brought it in (and please note that the exclude needs to specify the scala binary version, e.g. _2.11 etc.!):

...exclude("org.scalatest", "scalatest_2.11")

There had also been a warning in the event log before the exclude:

SBT project import
[warn] Multiple dependencies with the same organization/name but different versions.
[warn]  * org.scalatest:scalatest_2.11:(2.2.6, 3.0.1)
