Need to have a repository named repo1 in instance http://localhost:4545.
Active apex plugin in repo1 but not in root.
Go to http://localhost:4545/repo1, css will not load. Any link to a file will go to http://localhost:4545/file.html instead of http://localhost:4545/repo1/file.html.
Redirect 30X from http://localhost:4545/repo1 to http://localhost:4545/repo1/
Maybe try with a base-href="/repo1/"
