Hello Andy, The error occurs because you use SvnRepositoryGetLock incorrectly. This class is an analog of one of "svnlook" commands, it requires local access to FSFS repository. To get locks use svnOperationFactory.createGetInfo() method. Have a look at the test that I've added for you as an example in r9744-9745. The test code is below: @Test public void testSvnRepositoryGetLock() throws Exception { final TestOptions options = TestOptions.getInstance(); final SvnOperationFactory svnOperationFactory = new SvnOperationFactory(); final Sandbox sandbox = Sandbox.createWithCleanup(getClass().getSimpleName() + ".testSvnRepositoryGetLock", options); try { final SVNURL url = sandbox.createSvnRepository(); final CommitBuilder commitBuilder = new CommitBuilder(url); commitBuilder.addFile("directory/file"); commitBuilder.commit(); final WorkingCopy workingCopy = sandbox.checkoutNewWorkingCopy(url); final File file = workingCopy.getFile("directory/file"); final String expectedLockMessage = "Lock message"; final String expectedLockOwner = "owner"; final SvnSetLock setLock = svnOperationFactory.createSetLock(); svnOperationFactory.setAuthenticationManager(new BasicAuthenticationManager(expectedLockOwner, null)); setLock.setSingleTarget(SvnTarget.fromFile(file)); setLock.setLockMessage(expectedLockMessage); setLock.setStealLock(true); setLock.run(); //svnlook-like way to obtain lock, requires access to FSFS repository final SvnRepositoryGetLock getLock = svnOperationFactory.createRepositoryGetLock(); getLock.setRepositoryRoot(new File(url.getPath())); getLock.setPath("directory/file"); SVNLock lock = getLock.run(); checkLockOwnerAndMessage(expectedLockMessage, expectedLockOwner, lock); //svn info-like way to obtain lock, requires only working copy (even working copy is not mandatory, one can use SvnTarget#fromURL) final SvnGetInfo getInfo = svnOperationFactory.createGetInfo(); getInfo.setSingleTarget(SvnTarget.fromFile(file)); final SvnInfo info = getInfo.run(); lock = info.getLock(); checkLockOwnerAndMessage(expectedLockMessage, expectedLockOwner, lock); } finally { svnOperationFactory.dispose(); sandbox.dispose(); } } private void checkLockOwnerAndMessage(String expectedLockMessage, String expectedLockOwner, SVNLock lock) { String actualLockOwner = lock == null ? null : lock.getOwner(); String actualLockMessage = lock == null ? null : lock.getComment(); Assert.assertEquals(expectedLockOwner, actualLockOwner); Assert.assertEquals(expectedLockMessage, actualLockMessage); } -- Dmitry Pavlenko, TMate Software, http://subgit.com/ - git-svn bridge > I'm trying to determine whether or not a file is locked, and if so, > what the username of the lock's owner is.
