Hello Zsolt,

This could be the reason - there is a limitation on Windows for file
path - its length shouldn't exceed 260 characters. This limitation could
be worked around by prepedning "\\?\" to the file path, but only when
done inside JVM native code, so we could do nothing about it.

There is a bug at
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4403166 and it is
marked as closed, but from user comments it doesn't look like it is
actually fixed even in the latest version of JDK.

However, taking in account path you've sent -
"C:/DOKUME~1/zk/LOKALE~1/Temp/cbrepository507", even with ~ expanded its
length shouldn't exceed path length limit. That is why I was suspecting
that the reason of the problem are "~" characters. SVNURL.fromFile(new
File(file.getCanonicalPath())) should expand them.

I tried to perform some tests with that (creating repository in windows
temp directory (File.createTempFile() using both "shortened" and full
path). For me both versions worked fine (Windows XP, SP2, JDK 1.4 and 1.6):

absolute: C:\DOCUME~1\ALEXAN~1.KIT\LOCALS~1\Temp\cbrepository8521
url: file:///C:/DOCUME~1/ALEXAN~1.KIT/LOCALS~1/Temp/cbrepository8521
uuid: 1b3dec6b-1501-0010-adb1-95a35d681201

canonical: C:\Documents and Settings\Alexander.Kitaev\Local
Settings\Temp\cbrepository8521
url:
file:///C:/Documents%20and%20Settings/Alexander.Kitaev/Local%20Settings/Temp/cbrepository8521
uuid: 1b3dec6b-1501-0010-adb1-95a35d6812

Test code:

FSRepositoryFactory.setup();
               
File tmp = File.createTempFile("cbrepository", "");
SVNFileUtil.deleteAll(tmp, true);
System.out.println("absolute: " + tmp.getAbsolutePath());
SVNRepositoryFactory.createLocalRepository(tmp, false, false);

try {
  SVNURL url = SVNURL.fromFile(tmp);
  SVNRepository repos = SVNRepositoryFactory.create(url);
  repos.testConnection();
  System.out.println("url: " + url);
  System.out.println("uuid: " + repos.getRepositoryUUID(false));
} catch (SVNException e) {
  System.out.println("error: " + e.getMessage());
}

tmp = new File(tmp.getCanonicalPath());
System.out.println("canonical: " + tmp);

try {
  SVNURL url = SVNURL.fromFile(tmp);
  System.out.println("url: " + url);
  SVNRepository repos = SVNRepositoryFactory.create(url);
  repos.testConnection();
  System.out.println("uuid: " + repos.getRepositoryUUID(false));
} catch (SVNException e) {
  System.out.println("error: " + e.getMessage());
}

SVNFileUtil.deleteAll(tmp, true);
System.exit(0);
