Hi,

I want to get information on the various revisions of a file:
- who commited
- when
- what changed
And I want this for all revisions (and all files, but this is easy). So
I wanted to iteratively diff a file's revision with its previous
revision, and then take this previous revision and diff again with the
preceding one, ...

However, I cannot figure out how to use diff (or even what diff to use).

Example:

/** display the differences between two paths. */
diff(path, outFile, recurse)
-> what two paths are these? There is only one parameter.

/** display the differences between WC and url */
diff(path, url, urlRevision, outFile, recurse)
-> OK, this one seems more straight forward

SvnKitClientAdapter svnClientSVNUrl = new SvnKitClientAdapter();
svnClient.setUsername("test");
svnClient.setPassword("test");
url = new SVNUrl("file:///var/local/svn/TestSVNJavaClient");
svnClient.checkout(url, new File("/tmp/testSVN"), SVNRevision.HEAD, true);
// test one file in the project
svnClient.diff("/tmp/testSVN/src/Main.java", url, SVNRevision.PREVIOUS, new File("/tmp/testSVN/src/Main.diff"), false);

-> it gives me the following error:
Exception in thread "main" java.lang.NoSuchMethodError: org.tigris.subversion.javahl.Depth.fromRecurse(Z)I
        at org.tmatesoft.svn.core.javahl.SVNClientImpl.diff(SVNClientImpl.java:668)
        at org.tmatesoft.svn.core.javahl.SVNClientImpl.diff(SVNClientImpl.java:664)
        at org.tigris.subversion.svnclientadapter.javahl.AbstractJhlClientAdapter.diff(AbstractJhlClientAdapter.java:2359)
        at Main.main(Main.java:26)

(line 26 is the diff instruction)

So I try another one:

/** display the differences between two urls */
diff(url, oldUrlRevision, newUrlRevision, outFile, recurse)

// test one file in the project
svnClient.diff(new SVNUrl("file:///var/local/svn/TestSVNJavaClient/src/Main.java"), SVNRevision.PREVIOUS, SVNRevision.HEAD, new File("/tmp/testSVN/src/Main.diff"), false);

-> gives me the same exception.

Exception in thread "main" java.lang.NoSuchMethodError: org.tigris.subversion.javahl.Depth.fromRecurse(Z)I
        at org.tmatesoft.svn.core.javahl.SVNClientImpl.diff(SVNClientImpl.java:668)
        at org.tigris.subversion.svnclientadapter.javahl.AbstractJhlClientAdapter.diff(AbstractJhlClientAdapter.java:1617)
        at org.tigris.subversion.svnclientadapter.javahl.AbstractJhlClientAdapter.diff(AbstractJhlClientAdapter.java:1541)
        at org.tigris.subversion.svnclientadapter.javahl.AbstractJhlClientAdapter.diff(AbstractJhlClientAdapter.java:1629)
        at Main.main(Main.java:26)

As you can see, there is something I didn't get about the diff :-(
Any help will be appreciated
