The svn client 'svnkit' is not available

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 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).

  • Getting directory listing from SVN for use in ANT dropdown
  • Managing releases on github
  • Jenkins unable to invoke ANT in MAC Slave
  • Replace tokens from one file to another using Ant script
  • How to fork a background process in Jenkins? Setting BUILD_ID and using nohup seems to be non working
  • build.gradle changes for git submodule
  • 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/" />
        <typedef resource="org/tigris/subversion/svnant/svnantlib.xml" classpathref="test.classpath.dep" />
        <echo message="Creating tag ${env.tag_name}" />
        <svnSetting username="${user}" password="${password}" client="svnkit" />
            <copy srcUrl="[srcUrl]" destUrl="[destUrl]" message="${env.tag_name}" />

    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:

    Does someone have an idea that could solve this problem?

  • SVN Externals unexpected state issue
  • From svn to git, with a moved trunk
  • How does bug tracker/version control integration work with typical git workflows?
  • SVN and revision numbers
  • How do I implement the Post Commit Hook with Trac & SVN in a Windows Environment?
  • One Solution collect form web for “The svn client 'svnkit' is not available”

    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">
        <macrodef name="svn-checkout">
            <attribute name="src"/>
            <attribute name="dest"/>
                <mkdir dir="@{dest}"/>
                <java classname="org.tmatesoft.svn.cli.SVN" dir="@{dest}" fork="true" classpathref="build.path">

                    <arg line="--password ${svn.pass}"/>
                    <arg value="checkout"/>
                    <arg value="@{src}"/>

    • This example uses the ivy cachepath task to download the dependencies into a local classpath reference called “build.path”.
