IntelliJ CE Red Markers

Question

My IntelliJ is showing warnings in Red color. For example "Whitespace at end of line", "Are you sure you want to println? If yes, ...."

I have tried changing the setting at many place, no avail. For now, I am using Scala.

EDIT: I still want to see the warning, but not in Red color. I have tried changing this in the following settings, but it did not help. Where else can this be fixed?

Answer 1

As @MateuszKubuszok mentioned in the comment, it is a scalastyle error. Here is the place that holds part of the message you are seeing. Basically you have three options:

1. Fix that warning by removing the spaces. (The best IMHO)

2. Wrap this line in scalastyle:off as suggested:

   // scalastyle:off
   println("Why?") // Followed by spaces          
   // scalastyle:on
   

3. Disable this rule. At the root of this project there is a file called scalastyle-config.xml. In it there is a line:

   <check level="warning" class="org.scalastyle.file.WhitespaceEndOfLineChecker" enabled="true"></check>
   

   Change it into:

   <check level="warning" class="org.scalastyle.file.WhitespaceEndOfLineChecker" enabled="false"></check>
   

   will make this rule to not check your code.
