I have been using svnant 1.3.0 to create tags from branches in my SVN repository. Now I have upgraded from SVN 1.6 to 1.7 and there is no released svnant binary that supports it. But I have downloaded the svnant 1.4 source from tigris.org and build a svnant.jar.
I know that svnant has a few dependecies and I have the following: svnkit 1.7.5 (from svnant repository), svnjavahl (from svnant repository), svnClientAdapter (from svnant repository), svnkit-cli (from svnant repository), trilead-ssh 1.0 (from maven repository) and ganymed-ssh.jar build 210 (from maven repository).
I use IVY for dependency management and have added all the above jars (except for the two from maven repository) to my Artifactory installation. In my IVY dependency file I retrieve the jars like so:
<dependency org="svnant" name="svnant" rev="1.4.0" conf="test->default" />
<dependency org="svnkit" name="svnkit" rev="1.7.5" conf="test->default" />
<dependency org="svnjavahl" name="svnjavahl" rev="1.4.0" conf="test->default" />
<dependency org="svnClientAdapter" name="svnClientAdapter" rev="1.4.0" conf="test->default" />
<dependency org="svnkit-cli" name="svnkit-cli" rev="1.7.5"/>
<dependency org="trilead-ssh2" name="trilead-ssh2" rev="1.0.0" conf="test->default"/>
<dependency org="ch.ethz.ganymed" name="ganymed-ssh2" rev="build210" conf="test->default" />
All jars are retrieved correctly. I try to do a branch2tag copy like so (The retrieveIVY target retrieves the jar files described above):
<target name="create-tag" depends="retrieveIVY">
<taskdef classpathref="test.classpath.dep" resource="net/sf/antcontrib/antcontrib.properties" />
<typedef resource="org/tigris/subversion/svnant/svnantlib.xml" classpathref="test.classpath.dep" />
<echo message="Creating tag ${env.tag_name}" />
<svnSetting username="${user}" password="${password}" client="svnkit" />
<svn>
<copy srcUrl="[srcUrl]" destUrl="[destUrl]" message="${env.tag_name}" />
</svn>
</target>
This worked with svnant 1.3.0 and SVN 1.6 (apart from the svnSetting tag). But using the new jar versions I get the following error:
The svn client 'svnkit' is not available !

Does someone have an idea that could solve this problem?
I would advise using the svnkit java classes directly instead of struggling with the svnant task. This approach, combined with a macrodef, will result in a similar but more reliable solution.
<project name="build" default="checkout" xmlns:ivy="antlib:org.apache.ivy.ant">

Note:
- This example uses the ivy cachepath task to download the dependencies into a local classpath reference called "build.path".
