Don't use plain

File

type for your properties. Use

RegularFile

and then link them together. Then it should work properly

Thanks for the reply, Even with RegularFile it does not help. I am getting the same error says "A problem was found with the configuration of task ':addQuoteSource' (type 'AddQuoteSource'). - In plugin 'com.vitesco.abe.main' type 'com.vitesco.abe.gradle.tasks.AddQuoteSource' property 'inputFile' specifies file 'D:\src\demo\duqd2_1u_iab\quote-with-quotation-marks.txt' which doesn't exist. Reason: An input file was expected to be present but it doesn't exist. Possible solutions: 1. Make sure the file exists before the task is called. 2. Make sure that the task which produces the file is declared as an input. Please refer to https://docs.gradle.org/7.4.2/userguide/validation_problems.html#input_file_does_not_exist for more details about this problem. * Try:

Run with --stacktrace option to get the stack trace.

Run with --info or --debug option to get more log output.

Run with --scan to get full insights.

How does your code look now? (Please use code tags, not plain text)

Thank you for the reply, I modified the code as you suggested but it does not work as expected (see console output). Could you please have look of my code and help me?

Sorry, I mistyped, I meant

RegularFileProperty

, not

RegularFile

. Also, never do such own implementations but use it properly like documented. And another side-note, it is pretty useless to use task configuration avoidance (

tasks.register

) if you then right away call

.get()

on the providers and thus force immediate realization. Instead user methods like

configure()

,

map()

, or

flatMap()

.
