There is an unrelated mistake in the regex of the parameter type of your reproducer. So to make this discussion easier I will be using this parameter type declaration to trigger the exception: package com.example.bug
import io.cucumber.java8.En
class HtmlSafeStringStepdefs : En {
init {
ParameterType("html_safe_string", "html_safe\\(\"(.*)\"\\)") { string: String ->
HtmlSafeString(string)
}
}
}And this is essentially the same as using a lambda reference: package com.example.bug
import io.cucumber.java8.En
class HtmlSafeStringStepdefs: En {
var htmlSafeString: HtmlSafeString? = null
init {
ParameterType("html_safe_string", "html_safe\\(\"(.*)\"\\)", ::HtmlSafeString)
}
}When declaring a Because And we want to get the non-bridge Unfortunately this gets a bit complicated when the target is a method reference to a value class. Because the class is inlined the real method has been name mangled into As such you have the following options.
package com.example.bug
import io.cucumber.java8.En
class HtmlSafeStringStepdefs : En {
init {
ParameterType("html_safe_string", "html_safe\\(\".*\"\\)") { string: String ->
{
HtmlSafeString(string)
}
}
}
}

Option 3 seems a bit tricky so I might be going with option 2. Edit: Scratch that, option 2 doesn't work for me. Also, I see there is wind of cucumber-java8 being deprecated. Is the replacement available? Maybe it doesn't have the issue. |

We're considering a lambda based implementation in #2279. It'd need someone willing to implement it. |

Given you are implementing a feature:
And step definitions:
And supposing you implemented the class like this:
When you compile, everything goes fine.
Then when you run, you expect the specifications to be run.
But you actually get this:

Where I actually hit this was trying to wrap
TupleintoPointandVectorvalue classes for Red Rocket.The text was updated successfully, but these errors were encountered:
