I'm using intellij community 2018.3 with scala 2.12.
I try to generate scaladoc of my project (a library) but intellij print me this error:

IDE is update. What can I do?
It could be the following:
Also you are on scala 2.12, scala reflect seems to be on 2.11 or other version.
Add a dependency to scala reflect to your project:
https://mvnrepository.com/artifact/org.scala-lang/scala-reflect/2.12.8

I like to use developing and debugging engines with IntelliJ IDEA, but I got an error. I used this link: https://predictionio.apache.org/resources/intellij/.
Please guide me.

I had same issue and fix it changing the scala version to 2.11.3 in build.sbt.
The json library used by predictionio uses the scala's version 2.11.3 .
When right-click running a test class, Eclipse failed with

Yet it ran in the command line with sbt test. The libraries have been updated as described in java.lang.NoClassDefFoundError: scala/Product$class.
This happened with the latest Scala IDE (4.7.0-vfinal-2017-09-29T14:34:02Z-Typesafe) with the patmat project from Coursera's scala course.
What is the cause and how can it be fixed?
Requested info
The Java Build Path is
You have a combination of _2.11 libraries and 2.12.3 Scala library, this won't work. It looks like the _2.11 dependendencies come from SBT (judging from the paths).
You need to either change Scala IDE's Scala version (setting correct scala version on scala ide explains how) or set scalaVersion := "2.12.3" in the SBT project and rerun sbt eclipse.
Please use the Scala library version 2.11 as the other Scala based dependencies like scala-xml and scalatest are based on Scala library version 2.11
Running Specs2 in IntelliJ fails. Running the same tests manually via an SBT task works just fine without any problems.
Message: "Test framework quit unexpectedly"
IntelliJ: v.15.0.5 or 2016.2 EAP (build #IC-162.426.1)
Platform: Scala 2.11.7, SBT 0.13.8, Specs2 2.4.17, Play! 2.3.10
This is a common error response, but it looks like the root cause is different for a lot of other people. I have troubleshoot this issue before and corrected it by adding the following to build.sbt:
fork in Test := false
parallelExecution in Test := false
Now the tests are failing again. I have looked through the revision history of our build.sbt file but I do not notice anything significant that would instigate such a regression and I have no clues.
Upon step-debugging the crash I have found the following root cause:

scalaz.Tree is a transitive dependency of many other dependencies in my project that request versions including 7.1.1, 7.1.2, 7.1.3, 7.0.6 of scalaz. It's interesting to note that in 7.0.x scalaz.Tree is a trait (interface in Java vernacular) but an abstract class in 7.1.x, so this may constitute the root cause.
Is it possible to resolve this issue given the transitive dependency conflicts with scalaz 7.1.x and 7.0.x which are evidentially incompatible?
Specs2 2.4.17 uses Scalaz 7.1.0. Some other dependency in your build is probably dragging a Scalaz 7.2.x dependency. I suggest that you update your specs2 version to 3.8.4 which will bring a more recent version of Scalaz in scope.
I'm unable to figure out what is wrong with this program? I'm using an older verison of scala (2.7) because its compatible with certain libraries i'm using
Here is a simple program i'm attempting to run.
The program runs fine using scalac and scala commands.
However on IntelliJ 14+ -> when i create a new project -> select the compiler (scala 2.7) and try to run the above program i get this error below
object SimpleClass {
def main(args: Array[String]) {
println("This is a simple Class")
}
}
Error output.
Why does intelliJ throw the ClassNotFoundException? I've saved the program as SimpleClass.scala

Recent Scala for IntelliJ IDEA is based on sbt. Apparently Scala 2.7.3 is not supported any longer in this configuration. If you set up a project, IntelliJ will offer you (when you select "Download" for the SDK) no version older than Scala 2.8.0. If you manually select 2.7.3, the following happens when you try to compile:
Error:scalac: Error: org.jetbrains.jps.incremental.scala.remote.ServerException
Error compiling sbt component 'compiler-interface-2.7.3.final-52.0'

at sbt.IO$.withTemporaryDirectory(IO.scala:285)
at sbt.compiler.AnalyzingCompiler$$anonfun$compileSources$1.apply(AnalyzingCompiler.scala:142)
at
...
The next step is Scala 2.8.2, for which you get:
Error:scalac: Parameter '-nobootcp' is not recognised by Scalac.
It seems the oldest Scala that works with the current IntelliJ is 2.9.0. (You have to use Java 7 and not Java 8 for this!)
The solution would be to downgrade IntelliJ IDEA to an old version that still supports Scala 2.7.3 (perhaps IDEA 11?), or to simply set up the project with Scala 2.9.3, but compile instead manually (or using sbt from the terminal) against 2.7.3.
If you have the source to the library that requires 2.7.3, perhaps the best option is to try to compile the library with contemporary versions of Scala (at least 2.9.0).
I'm running scala 2.8.0 SDK & Scala Plugin 1.5.2 (latest version) on IntelliJ 14.1.4 (also latest) with java-7-openjdk
object HelloWorld {
def main(args: Array[String]) {
println("Hello, world!")
}
}
This is the error I'm receiving
Is there any settings i might have to change to get this to run?
The program runs as a Scala Script on Idea IntelliJ
I must use scala 2.8.0 only not a later version, i'd be happy to change anything else

Out of curiosity, have you tried to use a different JDK?
Maybe JDK6 Hotspot or even JDK7 Hotspot?
I ask because I have seen errors similar to Error compiling sbt component 'compiler-interface-2.8.0.final-51.0' in the past, and they were usually related to incompatibilities with a library and a JDK version.
I cannot test right now, but I will give a look later and try to reproduce if it is still an issue.
For future travellers also setting up Scala for the first time:
I had similar issues and found changing the "Project Interpreter" to the correct JDK (OpenJDK 11 instead of my previous JDK 8) worked.
See e.g.
https://stackoverflow.com/a/29286865/10447904
Many other SO answers that I stumbled across focused on setting the correct JDK using Settings -> Build -> Scala Compiler Server or on the configuration files, but neither of these worked for me.
