SVN Error: svn: E200007: Runner for 'org.tmatesoft.svn.core.wc2.SvnMerge'

Question

I am trying to merge branch to trunk using SVNKIT java API.

The code for it is as follows:

String branchURL = "<Branch URL>";

SVNURL branchSVNURL = SVNURL.parseURIDecoded(branchURL);//SVN Branch URL

String WC_PATH= "<Some Path>";//This is the Working copy path which has the Trunk checked out

File svnWorkingCopy = new File(WC_PATH);

SVNDiffClient svnDiffClient;//This is initialized using SVNClientManager

try{
      //doMerge(java.io.File path1, SVNRevision revision1, SVNURL url2, SVNRevision revision2, java.io.File dstPath, SVNDepth depth, boolean useAncestry, boolean force, boolean dryRun, boolean recordOnly) 
      svnDiffClient.doMerge(branchSVNURL, SVNRevision.HEAD,null,svnWorkingCopy,SVNDepth.INFINITY,false, false, false, false);
   }catch(Exception e){
     e.printStackTrace();
   }

Running this code throws the following error:

org.tmatesoft.svn.core.SVNException: svn: E200007: Runner for 'org.tmatesoft.svn.core.wc2.SvnMerge' command have not been found; probably not yet implement in this API.

I ran this piece of code with SVNKIT version 1.7.11 and 1.8.10 and got the same error.

SVN command line equivalent for the code mentioned above is

svn merge <branchurl> <WC_PATH>

Let know if anything needs to be done to fix this issue.

First, check you have subclipse installed, @flm post where. In your Eclipse, go Windows -> Preference -> Team -> SVN -> DIFF/Merge

Select default (Sublclipse)
