1. getResources("jar:file:/Users/xxxxx/.gradle/caches/modules-2/files-2.1/com.example1/example1/1.0.0/92cc99358ea6b25f5b9981c2a3f04e595705403f/example2-1.0.0.jar!/com/example1/")
2. field rootDirCache will cache jar:file:/Users/xxxxx/.gradle/caches/modules-2/files-2.1/com.example1/example1/1.0.0/92cc99358ea6b25f5b9981c2a3f04e595705403f/example2-1.0.0.jar!/com/example1/

Path judgment should be added to avoid caching invalid paths

Old

if (currentPrefix != null) {
	// A prefix match found, potentially to be turned into a common parent cache entry.
	if (commonPrefix == null || !commonUnique || currentPrefix.length() > commonPrefix.length()) {
		commonPrefix = currentPrefix;
		existingPath = path;
	}
	else if (currentPrefix.equals(commonPrefix)) {
		commonUnique = false;
	}
}

New

if (currentPrefix != null) {
	boolean startsWithJar = currentPrefix.startsWith("jar:");
	boolean containsJarExclamation = currentPrefix.contains(".jar!");
	if (startsWithJar && containsJarExclamation) {
		// A prefix match found, potentially to be turned into a common parent cache entry.
		if (commonPrefix == null || !commonUnique || currentPrefix.length() > commonPrefix.length()) {
			commonPrefix = currentPrefix;
			existingPath = path;
		}
		else if (currentPrefix.equals(commonPrefix)) {
			commonUnique = false;
		}
	}
}

@jhoeller : When will this issue be fixed? We are currently blocked by it and had to rollback the update of Spring

@stephanie-dm, as you can see on the right, this issue is scheduled for 6.2.2.
