z2-Environment

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.

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:

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();
    }

}
