IntelliJ check problem during Hyperskill Kotlin learning - kotlin

Question

I'm working on a Jetbrains Hyperskill track KOTLIN, it's my third project and I never had this kind of problem.
I found this post (here), and tried their suggestions (Which are the same that JetBrains give on their wiki/FAQ), but didn't work.
The project is:
Unit Converter (Heavy Duty Step 4/5)
Here is my code:
package converter
fun main() {
loopcheck# while (true) {
var conversion: Double
print("Enter what you want to convert (or exit): ")
val userInput = readln()
if (userInput == "exit") break#loopcheck
val (originalNumber, originalUnit, convertedUnit) = userInputSplit(userInput)
// Validating inputs/Enums + exception checks
if (originalNumber == null) {
println("Wrong number")
continue#loopcheck
}
if (originalUnit == null && convertedUnit != null) {
println("Conversion from ??? to $convertedUnit is impossible")
continue#loopcheck
}
if (originalUnit != null && convertedUnit == null) {
println("Conversion from $originalUnit to ??? is impossible")
continue#loopcheck
}
if (originalUnit == null && convertedUnit == null) {
println("Conversion from ??? to ??? is impossible")
continue#loopcheck
}
if (originalUnit != null && convertedUnit != null) {
if (originalUnit.type != convertedUnit.type) {
println("Conversion from ${originalUnit.plural} to ${convertedUnit.plural} is impossible")
continue#loopcheck
} else {
// Conversion Calculus
conversion = originalNumber * originalUnit.ratio / convertedUnit.ratio
// Check if the units are singular or plural
val preUnitCheck = if (originalNumber == 1.0) originalUnit.singular else originalUnit.plural
val postUnitCheck = if (conversion == 1.0) convertedUnit.singular else convertedUnit.plural
// Prints final text
println("$originalNumber $preUnitCheck is $conversion $postUnitCheck")
}
}
}
}
// Function to organize userInput in 3 variables: Number Unit1 Unit2
fun userInputSplit(userInput: String): Triple<Double?, Unidade?, Unidade?> {
val userInputArray = userInput.lowercase().split(" ")
val originalNumber = try {
userInputArray[0].toDouble()
} catch (e: NumberFormatException) { null }
val originalUnit = try {
getUnit(userInputArray[1])
} catch (e: IllegalArgumentException) { null }
val convertedUnit = try {
getUnit(userInputArray[2])
} catch (e: IllegalArgumentException) { null }
return Triple(originalNumber, originalUnit, convertedUnit)
}
// Function to set constant from Unidade for conversion based from User Input.
fun getUnit(unit: String): Unidade =
when (unit) {
"m", "meter", "meters" -> Unidade.METER
"km", "kilometer", "kilometers" -> Unidade.KILOMETER
"cm", "centimeter", "centimeters" -> Unidade.CENTIMETER
"mm", "millimeter", "millimeters" -> Unidade.MILLIMETER
"mi", "mile", "miles" -> Unidade.MILE
"yd", "yard", "yards" -> Unidade.YARD
"ft", "foot", "feet" -> Unidade.FOOT
"in", "inch", "inches" -> Unidade.INCH
"g", "gram", "grams" -> Unidade.GRAM
"kg", "kilogram", "kilograms" -> Unidade.KILOGRAM
"mg", "milligram", "milligrams" -> Unidade.MILLIGRAM
"lb", "pound", "pounds" -> Unidade.POUND
"oz", "ounce", "ounces" -> Unidade.OUNCE
// "degree celsius", "degrees celsius", "celsius", "dc", "c" -> Unit.CELSIUS
// "degree fahrenheit", "degrees fahrenheit", "fahrenheit", "df", "f" -> Unit.FAHRENHEIT
// "kelvin", "kelvins", "k" -> Unit.Kelvin
else -> throw IllegalArgumentException ("Wrong Unit. Try Again.")
}
enum class Unidade (val short: String,
val singular: String,
val plural: String,
val ratio: Double,
val type: String
) {
METER("m","meter", "meters", 1.0, "Length"),
KILOMETER("km","kilometer", "kilometers", 1000.0, "Length"),
CENTIMETER("cm","centimeter", "centimeters", 0.01, "Length"),

Every time I try to check my code with Hyperskill, this happens now:

Answer 1

Open the build.gradle file in the root directory of your JetBrains Academy project and replace testImplementation 'com.github.hyperskill:hs-test:release-SNAPSHOT' with testImplementation 'com.github.hyperskill:hs-test:master-SNAPSHOT'.

Answer 2

After reaching JETBRAINS support we did some actions. In the end, the problem was solved. Down below the steps taken.
1st try:
Open build.gradle in your project folder and replace
testImplementation 'com.github.hyperskill:hs-test:release-SNAPSHOT'
with testImplementation
'com.github.hyperskill:hs-test:master-SNAPSHOT'
The build output after the modification changed to a different error message.

FAILURE: Build failed with an exception.
What went wrong: Execution failed for task ':Unit_Converter-task:compileTestKotlin'.
After this error, Jetbrains support suggested new steps:
Please try re-creating the project by following the steps below: Go to
the affected JetBrains Academy project’s directory and move it
somewhere else or make a backup.
On the Welcome Screen of your IDE, go to the My Courses tab. Highlight
the affected project and click ✕. Select Remove Course.
Start a JetBrains Academy project by going to the JetBrains Academy
tab in File | Learn and Teach | Browse Courses.
After that, please ensure that JDK 17 is selected as Gradle JVM in
Settings/Preferences | Build, Execution, Deployment | Build Tools |
Gradle and as Project SDK in File | Project Structure.
I've changed and updated everything as suggested and the build output changed AGAIN:

After sending this output to Jetbrains they requested again to open build.gradle in my project folder and replace testImplementation 'com.github.hyperskill:hs-test:release-SNAPSHOT' with testImplementation 'com.github.hyperskill:hs-test:master-SNAPSHOT'.
This answer took 2-3 days to be replied. After that, the check worked.
