[JENKINS-75180] String is appended in the report url generated by HTML Publisher plugin

[jenkins-infra-bot]

The HTML Publisher Plugin is generating an incorrect URL for the published HTML reports. Instead of using the actual file name from the Index page[s] pattern, it creates a directory with a modified name, leading to broken links.

Steps to Reproduce:

1. Install Jenkins: Install and configure a Jenkins instance.
2. Install HTML Publisher Plugin: Install the HTML Publisher Plugin from the Jenkins Plugin Manager.
3. Create a Job: Create a new freestyle job in Jenkins.
4. Configure Build Steps: Add build steps to generate HTML reports (e.g., run a test suite that produces HTML output). Ensure the generated reports are placed in a directory named "report" within the build artifacts. In this example, the report file is named "byteblower_20250123_054647.html" and is located in job///artifact/report/byteblower_20250123_054647.html.
5. Configure HTML Publisher:
   • In the "Publish HTML reports" section, configure the following:
     • HTML directory to archive: report/
     • Index page[s]: byteblower_*.html
     • Index page title[s] (Optional): Byteblower Report
     • Report title: Byteblower Report
6. Run the Job: Trigger the job to run.
7. Verify Results:
   • Go to the job's build page and navigate to the "Published Reports" section.
   • Observe the generated URL for the HTML report. It should be in the format: http:///job///report/
   • However, the url generated by the plugin is "http://localhost:8080/job///Byteblower_20Report/"

Question: Why is the string "Byteblower_20Report" appended? is this configurable? 

We are trying to perform automation, so need to check whether this is a bug or an expected behavior.

Raw content of original issue

The HTML Publisher Plugin is generating an incorrect URL for the published HTML reports. Instead of using the actual file name from the Index page[s] pattern, it creates a directory with a modified name, leading to broken links.

Steps to Reproduce:

	
Install Jenkins: Install and configure a Jenkins instance.
	
Install HTML Publisher Plugin: Install the HTML Publisher Plugin from the Jenkins Plugin Manager.
	
Create a Job: Create a new freestyle job in Jenkins.
	
Configure Build Steps: Add build steps to generate HTML reports (e.g., run a test suite that produces HTML output). Ensure the generated reports are placed in a directory named "report" within the build artifacts. In this example, the report file is named "byteblower_20250123_054647.html" and is located in job/<job name>/<build_no>/artifact/report/byteblower_20250123_054647.html.
	
Configure HTML Publisher:
	

		
In the "Publish HTML reports" section, configure the following:
		

			
HTML directory to archive: report/
			
Index page[s]: byteblower_*.html
			
Index page title[s] (Optional): Byteblower Report
			
Report title: Byteblower Report
		
		
	
	
	
Run the Job: Trigger the job to run.
	
Verify Results:
	

		
Go to the job's build page and navigate to the "Published Reports" section.
		
Observe the generated URL for the HTML report. It should be in the format: http://<jenkins-server>/job/<job-name>/<build-number>/report/
		
However, the url generated by the plugin is "http://localhost:8080/job/<job-name>/<build number>/Byteblower_20Report/"
