Example 6 with ObjectReader

use of org.eclipse.jgit.lib.ObjectReader in project gerrit by GerritCodeReview.

the class AbstractQueryChangesTest method newPatchSet.

protected Change newPatchSet(TestRepository<Repo> repo, Change c) throws Exception {
    // Add a new file so the patch set is not a trivial rebase, to avoid default
    // Code-Review label copying.
    int n = c.currentPatchSetId().get() + 1;
    RevCommit commit = repo.parseBody(repo.commit().message("message").add("file" + n, "contents " + n).create());
    ChangeControl ctl = changeControlFactory.controlFor(db, c, user);
    PatchSetInserter inserter = patchSetFactory.create(ctl, new PatchSet.Id(c.getId(), n), commit).setNotify(NotifyHandling.NONE).setFireRevisionCreated(false).setValidate(false);
    try (BatchUpdate bu = updateFactory.create(db, c.getProject(), user, TimeUtil.nowTs());
