maven version "${version}" is too long (max 200 chars).

Error message

maven version "${version}" is too long (max 200 chars).

What it means

requireCoord() allows an optional version segment but caps its length at 200 characters. This ArgumentError is thrown when the third colon-separated segment is longer than 200 characters (it is not otherwise pattern-checked).

Solutions

1. Provide a real Maven version string, e.g. 'com.google.guava:guava:33.0.0-jre'.
2. Check the version variable for concatenation/copy-paste corruption and trim to the actual version.
3. If the version is intentionally absent, use the 2-segment form 'groupId:artifactId'.
4. Log/inspect the value being passed to see what is filling the version slot.

Example fix

// before
requireCoord(`com.google.guava:guava:${longBlob}`);
// after
requireCoord('com.google.guava:guava:33.0.0-jre');

function isValidVersion(v) {
  return v == null || (typeof v === 'string' && v.length <= 200);

function isShortVersion(v) {
  return v == null || (typeof v === 'string' && v.length <= 200);
}

try {
  requireCoord(input);
} catch (err) {
  console.error(`Version segment invalid: ${err.message}`);
}

When it happens

Trigger: Calling with a coordinate whose version segment exceeds 200 chars, e.g. 'g:a:' followed by a very long string, an accidentally repeated version range, or a pasted blob of text after the second colon.

Common situations: Copy/paste accidents where an entire line or URL is appended after the artifact; programmatic string concatenation with a corrupted version variable; YAML/JSON config where the version field absorbed adjacent lines.
