How to check if substring of string's array match to patterns from other string array

Question

I wonder if there is any groovy-way to check if substring of strings matches to patterns.

For example I have strings List (or array):

def Errors = ['File xyz cannot be created: No space left on device', 'File kjh has errors: some_error']

Then I have list of strings, for example def Patterns = ['Tests failed', 'No space left on device', 'Something goes wrong', ...some strings... ]

I would like to check if some elements of List Patterns are substrings of Errors elements .

In that example it should return true, because Patterns has No space left on device and Errors has 'File xyz cannot be created: No space left on device'.

I know how to write it very ulgy and not efficient by using two for loops and method contains, but I know that Groovy has much more powerfull built-in methods. I have tried with findAll(), but it doesnt worked at all.

Do you have any ideas? Is there any way to make it more clever?

Explicitly naming pattern and error:

patterns.find { pattern -> errors.find { error -> error.contains(pattern) } }  // -> No space left on device
patterns.any { pattern -> errors.find { error -> error.contains(pattern) } } // -> true

depending on what/how many you want to find.

Or even shorter:

patterns.find { errors.find { error -> error.contains(it) } }
patterns.any { errors.find { error -> error.contains(it) } }
