SVNKit的API主要分为两类：High Level API和Low Level API。 
通常情况下，我们使用High Level API即可完成工作任务。High Level API通过封装、使用Low Level API，使开发工作变得相对简单、容易。在此我们重点介绍High Level API。

一、建立仓库

public static SVNRepository getRepository(String url, String username, String password) {
    DAVRepositoryFactory.setup();
    SVNRepositoryFactoryImpl.setup();
    SVNRepository repository = null;
    SVNNodeKind nodeKind = null;
    try {
        repository = SVNRepositoryFactory.create(SVNURL.parseURIEncoded(url));
        ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(username, password);
        repository.setAuthenticationManager(authManager);
        nodeKind = repository.checkPath("", -1);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
    if (nodeKind == SVNNodeKind.NONE) {
        throw new RuntimeException("There is no entry at '" + url + "'.");
    } else if (nodeKind == SVNNodeKind.FILE) {
        throw new RuntimeException("The entry at '" + url + "' is a file while a directory was expected.");
    }
    return repository;
}
