java - Crawling GitHub with JGit -

-

i'm trying crawl github wiki jgit.
when try 1 url, worked fine. tried random url , got error.
please see extract of code:

import java.io.file; import java.io.ioexception;  import org.eclipse.jgit.api.git; import org.eclipse.jgit.api.errors.gitapiexception;  public class main {     // url error     string url = "https://github.com/radiant/radiant.wiki.git";     // url works     // string url = "https://github.com/wardcunningham/smallest-federated-wiki.wiki.git";      public static void main(string[] args) {         main m = new main();         m.jgittest();         system.out.println("done!");     }      public void jgittest() {         try {             file localpath = file.createtempfile("testgitrepository", "");             localpath.delete();             git.clonerepository().seturi(url).setdirectory(localpath).call();         } catch (ioexception | gitapiexception e) {             system.err.println("excepton: " + e.getmessage());             e.printstacktrace();         }     } }

this stack trace:

exception in thread "main" org.eclipse.jgit.dircache.invalidpathexception: invalid path (contains separator ':'): how-to:-create-an-extension.textile     @ org.eclipse.jgit.dircache.dircachecheckout.checkvalidpathsegment(dircachecheckout.java:1243)     @ org.eclipse.jgit.dircache.dircachecheckout.checkvalidpathsegment(dircachecheckout.java:1225)     @ org.eclipse.jgit.dircache.dircachecheckout.checkvalidpath(dircachecheckout.java:1185)     @ org.eclipse.jgit.dircache.dircachecheckout.processentry(dircachecheckout.java:311)     @ org.eclipse.jgit.dircache.dircachecheckout.prescanonetree(dircachecheckout.java:290)     @ org.eclipse.jgit.dircache.dircachecheckout.docheckout(dircachecheckout.java:408)     @ org.eclipse.jgit.dircache.dircachecheckout.checkout(dircachecheckout.java:393)     @ org.eclipse.jgit.api.clonecommand.checkout(clonecommand.java:236)     @ org.eclipse.jgit.api.clonecommand.call(clonecommand.java:127)     @ main.jgittest(main.java:21)     @ main.main(main.java:13)

if visit wiki page of url doesn't work (https://github.com/radiant/radiant/wiki), find page: how to: create extension.
title of page cause of error: invalid path (contains separator ':'): how-to:-create-an-extension.textile.

i assume need escape output.

i suppose on windows. can't create file on windows having ":" in name. jgit should handle somehow, suppose bug in jgit.
