The argument '%s' could not be parsed: %s

Error message

The argument '%s' could not be parsed: %s

What it means

Thrown by DoubleArgument.parseValue when Double.parseDouble raises NumberFormatException; the JDK message (e.g. 'For input string: "abc"') is chained into InvalidArgumentException. It marks a numeric option that received something that is not a parsable IEEE double.

Solutions

1. Provide a plain dot-decimal number, e.g. '1.5', with no units or thousand separators.
2. If the value comes from a locale-aware tool, convert ',' to '.' before passing it.
3. Validate the value with Double.parseDouble in your script before invoking the command.

Example fix

# before
mx profdiff ... --cur-decimals 2,5
# after
mx profdiff ... --cur-decimals 2.5

Double d;
try { d = Double.parseDouble(value); } catch (NumberFormatException e) { throw new IllegalArgumentException("Not a double: " + value); }

static boolean isParsableDouble(String s) {
    if (s == null || s.isEmpty()) return false;
    try { Double.parseDouble(s); return true; } catch (NumberFormatException e) { return false; }
}

try {
    parser.parse(args);
} catch (InvalidArgumentException e) {
    // message contains the JDK NumberFormatException text; correct the numeric option
}

When it happens

Trigger: Passing '--some-double=abc', '--some-double=1,5' (comma decimal separator from a locale), an empty string, or 'NaN-like' text that Double.parseDouble rejects, to any double-valued option registered in a profdiff-style parser.

Common situations: Locale-related decimal separators ('1,5' vs '1.5'), trailing units ('0.5x'), empty CI variables, or copy-paste of percentages like '50%'.
