KtLint + Gradle: java.lang.ClassCastException: class java.lang.String cannot be cast to class java.lang.Integer exception thrown when .editorconfig file is present
If you are submitting a bug, please include the following:
Summary of problem
Spotless fails with an java.lang.ClassCastException when running apply or check (stack trace below).
This only happens when an .editorconfig file is present. Even an empty one triggers an identical issue. The .editorconfig file is placed in the root project. Deleting the .editorconfig file or passing .setEditorConfigPath(null) to the KtLint config resolves the issue.
Contents of .editorconfig:
# Generated by KtLint 1.0.1 (code-style=ktlint_official)
[*.{kt,kts}]
end_of_line = lf
ij_kotlin_allow_trailing_comma = true
ij_kotlin_allow_trailing_comma_on_call_site = true
ij_kotlin_imports_layout = *,java.**,javax.**,kotlin.**,^
ij_kotlin_packages_to_use_import_on_demand = unset
indent_size = 4
indent_style = space
insert_final_newline = true
ktlint_chain_method_rule_force_multiline_when_chain_operator_count_greater_or_equal_than = unset
ktlint_class_signature_rule_force_multiline_when_parameter_count_greater_or_equal_than = 1
ktlint_code_style = ktlint_official
ktlint_function_naming_ignore_when_annotated_with = [unset]
ktlint_function_signature_body_expression_wrapping = multiline
ktlint_function_signature_rule_force_multiline_when_parameter_count_greater_or_equal_than = 2
ktlint_ignore_back_ticked_identifier = false
max_line_length = 140
but as mentioned earlier - it also happens with a completely empty file - contents seem irrelevant.
I've initially assumed it's a ktlint problem, so I've filed a bug there but it doesn't seem to happen when running ktlint from CLI directly, hence spotless/spotless-gradle is the suspect.

@pawelkw Could you try running gradle with --no-daemon? I bet the daemon caches .editorconfig contents, so it failed on you regardless the changes.

Yeah, it works with just ktlint_function_signature_rule_force_multiline_when_parameter_count_greater_or_equal_than commented and --no-daemon.
So is that another issue...? That the file cached somewhere, somehow? Or that is out of scope of spotless?
So is that another issue...? That the file cached somewhere, somehow?
I've already reported it https://github.com/diffplug/spotless/issues/1924
BTW, I've looked into logs, and it may be an issue on a KtLint API side — it doesn't look like they're properly converting the config value to int (at least not for every parameter).
This is a bug of Ktlint, addressing it to https://github.com/pinterest/ktlint/issues/2560.
Reopening this as this should be fixed by Spotless, see https://github.com/pinterest/ktlint/issues/2560#issuecomment-1962400828.
