Can't connect to SVN repository through SvnKit API

Question

We have a SVN repository, and I am able to connect to it through Tortoise. But when I try to connect to it through SvnKit, specifically svnRepository.testConnection() method, it says svn: E170001: Authentication required for .... The credentials passed in are the same ones I am using with Tortoise as well.

This particular component works fine with other repositories. Further, this repository is secured. But I am able to connect to other secure repositories as well.

Here's the error log.

Looking forward to a solution.

Answer 1

The solution is simple: call

svnRepository.setAuthenticationManager(...);

with a proper ISVNAuthenticationManager implementation.

SVNKit has already several ready-to-use implementations of this class. The simplest one is BasicAuthenticationManager which can be constructed by one or several SVNAuthentication. Each SVNAuthentication instance represents some kind of credentials (see its subclasses). So if, for example, your repository is secured by only username and password, you can construct SVNPasswordAuthentication with your password and then construct BasicAuthenticationManager using it and pass to SVNRepository.

Another useful implementation is DefaultSVNAuthenticationManager which describes "authentication data stored in ~/.subversion directory". To construct it you can use SVNWCUtil.createDefaultAuthenticationManager(). You can also customize this class, for example, to allow or disallow to enter a password from a keyboard in interactive mode, or to store or not to store entered password in in ~/.subversion directory (or also you can use another directory for that). To understand how to do that, I recommend you to look at SVNCommandEnvironment.createClientAuthenticationManager() which constructs ISVNAuthenticationManager implementation for command line utility.
