How to get rid of scalac ServerException with Inte

Question

This error prevents me from running the project.

Here are versions info :

~ ❯❯❯ java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
~ ❯❯❯ scala -version
cat: /release: No such file or directory
Scala code runner version 2.12.1 -- Copyright 2002-2016, LAMP/EPFL and Lightbend, Inc.

And I use IntelliJ 2016.3

In an external terminal and sbt, it works !

Answer 1

This question puts me on the way

so I check the JDK version and surprisingly IntelliJ and Nailgun didn't run with the same JDK.

~ ❯❯❯ ps -ef | grep java
  501  2290  2017   0  4:12PM ??         0:01.81 /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/bin/java … org.jetbrains.plugins.scala.nailgun.NailgunRunner 3200 6a73f540-1a80-476d-96d2-83ab8faaad95
  501  2291  2017   0  4:12PM ??         0:02.15 /Library/Java/JavaVirtualMachines/jdk1.8.0_112.jdk/Contents/Home/bin/java …

So I searched in the IntelliJ preferences and found out that Scala Compile Server was configured with an old JDK : 1.8.0_11. Bim !

I've just unchecked the checkbox Use external compile server

Answer 2

Note that in scala-2.12, scala binary file is a wrapper script.

It looks like your JAVA_HOME directory is not correctly set.

Take a look at line that reads (inside $SCALA_HOME/bin/scala):

java_release="$(cat $JAVA_HOME/release | grep JAVA_VERSION)"

Based on your output, it looks like JAVA_HOME is not set. What you get is:

cat: /release: No such file or directory

Answer 3

go to editconfiguration in intellij and choose in JRE drop down the jdk version which is installed in your system. and do rebuild, It worked for me.
