Background
I am trying to bring up my grails project, which stopped building all of a sudden (probably due to me playing around with my local maven repository). Now when I run the grails command, I get the following errors -
org.eclipse.aether.resolution.ArtifactDescriptorException: Failed to read artifact descriptor for xalan:serializer:jar:2.7.1

I followed this blog https://stackoverflow.com/a/36427118/351903 and added the certificate of the remote server to my Cacerts, but am now getting these errors -
sun.security.validator.ValidatorException: KeyUsage does not allow digital signatures
I tried to manually download the artefacts and then observed that this error resolves for that one and shows for the next artefact. So, I thought, if I could list down all the file names in a url like this https://repo1.maven.org/maven2/org/grails/grails-bootstrap/2.4.0/ and then curl all the file names and create them on my local, I could resolve this one by one for my dependencies, like this -
curl https://repo1.maven.org/maven2/org/grails/grails-bootstrap/2.4.0/grails-bootstrap-2.4.0-javadoc.jar -o 'grails-bootstrap-2.4.0-javadoc.jar'
However, I am however, unable to list down all the files for an artefact -
SandeepanNath:Desktop sandeepan.nath$ ssh https://repo1.maven.org ls -l /maven2/org/grails/grails-bootstrap/2.4.0/
ssh: Could not resolve hostname https://repo1.maven.org: nodename nor servname provided, or not known
SandeepanNath:Desktop sandeepan.nath$
Trying with the IP -
SandeepanNath:Desktop sandeepan.nath$ ssh 151.101.36.209 ls -l /maven2/org/grails/grails-bootstrap/2.4.0/
ssh: connect to host 151.101.36.209 port 22: Operation timed out
Then I understood that the only option I have is to scrape the url looking for links and then doing curl. But, I am unable to scrape as well due to ssl errors. I tried following this python example - https://www.geeksforgeeks.org/implementing-web-scraping-python-beautiful-soup/?ref=lbp
#This will not run on online IDE
import requests
from bs4 import BeautifulSoup
import ssl
URL = "http://www.values.com/inspirational-quotes"
r = requests.get(URL)
soup = BeautifulSoup(r.content, 'html5lib')
print(soup.prettify())
But I get this error -
