Is ‘value $ is not a member of stringcontext’ Error Caused by a Missing Scala Plugin?

This error message `”value $ is not a member of stringcontext”` typically occurs in Scala when you are trying to use string interpolation (e.g., using the `s` interpolator) but the syntax or context is not correct. String interpolation in Scala allows you to embed variables or expressions directly in a string.

Let’s understand this with a more detailed example and explanation.

Explanation

In Scala, string interpolation is done using the following prefixes:

• s: for basic interpolation
• f: for formatted strings
• raw: for raw strings without escape characters

Suppose you want to include a variable inside a string. With string interpolation, you can do it as follows:

val name = "John"
println(s"Hello, $name!")

The output will be:

Hello, John!

Common Causes for the Error

Missing `s` Interpolator

If you forget to put the `s` before the string, you will encounter the error:

val name = "John"
println("Hello, $name!")

This will generate the following compile-time error:

<console>:13: error: value $name is not a member of String
       println("Hello, $name!")

Unimported Dependencies or Plugins

Few other reasons could involve missing dependencies or incorrect setup of the Scala environment, but for this specific error, the most common reason is the missing `s` interpolator.

How to Fix

Ensure you prefix your string with the `s` interpolator:

val name = "John"
println(s"Hello, $name!")

Conclusion

To directly answer your question: No, the error “value $ is not a member of stringcontext” is not caused by a missing Scala plugin. It is caused by incorrect syntax, mainly missing the `s` interpolator in front of the string where you are using the `$` symbol for interpolation.

Make sure you always prefix your string with the correct interpolator (`s`, `f`, or `raw`) to avoid such issues.
