Improvement #2051

Updated by Henning Blohm about 5 years ago

h2. Acceptance Criteria 

 * Only the needed branch should be cloned 
 * Preferrably only a shallow clone should be created 

 * Alternatively, we could switch to per-component checkout from the repo. 


 h2. Implementation Hint 

 * See https://bugs.eclipse.org/bugs/show_bug.cgi?id=466858 for a starting point 

 For example, the following code should (but seemingly does not yet) only clone a single branch: 

 <pre> 
 <code> 
 package com.zfabrik.gitcr.test; 

 import java.io.File; 
 import java.util.Arrays; 

 import org.eclipse.jgit.api.Git; 
 import org.eclipse.jgit.api.ListBranchCommand.ListMode; 
 import org.eclipse.jgit.lib.ProgressMonitor; 
 import org.eclipse.jgit.lib.Ref; 
 import org.eclipse.jgit.transport.UsernamePasswordCredentialsProvider; 

 public class TestCheckout { 

	 /** 
	  *  		 https://bugs.eclipse.org/bugs/show_bug.cgi?id=466858 
	  */ 
	 public static void main(String[] args) throws Exception { 
		 Git r = Git.cloneRepository() 
		 .setCredentialsProvider(new UsernamePasswordCredentialsProvider("..","..")) 
		 .setDirectory(new File("somewhere")) 
		 .setURI("https://somehost/repo") 
		 .setCloneAllBranches(false) 
		 .setBranchesToClone(Arrays.asList("refs/heads/master")) 
		 .call(); 
	 } 
	
 } 
 </code> 
 </pre>
