Subject [Bug 59160] New: scp task does not support ipv6
Date Thu, 10 Mar 2016 13:00:51 GMT

            Bug ID: 59160
           Summary: scp task does not support ipv6
           Product: Ant
           Version: 1.9.6
          Hardware: PC
            Status: NEW
          Severity: major
          Priority: P2
         Component: Optional Tasks

The scp task doesnot handle ipv6 ip as hostname. The problem is in Scp class.
The method parseUri is wrongly extracting the ip address based on first
appearance of ":" after @ . But in IPv6 it is having more than one ":" in the
ip address.


For ip fd01:0:101:2608:0:11ff:fe42:e13c the scp task gets the hostname as fd01
as the host name is parsed based on the index of ":" after "@". It should use
lastIndexOf the ":" uri to get the proper hostname to support ipv6

The current implementation is :

 int indexOfPath = uri.indexOf(':', indexOfAt + 1);
        if(indexOfPath == -1)
            throw new BuildException((new StringBuilder()).append("no remote
path in ").append(uri).toString());
        setHost(uri.substring(indexOfAt + 1, indexOfPath));

The fix for bug :

int indexOfPath = uri.lastIndexOf(':');
     if (indexOfPath == -1) {
       throw new BuildException("no remote path in " + uri);

   setHost(uri.substring(indexOfAt + 1, indexOfPath));
