Examples with IntegrationConflictException com.google.gerrit.server.submit.IntegrationConflictException used on opensource projects

Example 1 with IntegrationConflictException

use of com.google.gerrit.server.submit.IntegrationConflictException in project gerrit by GerritCodeReview.

the class CherryPickChange method cherryPick.

/**
 * This function can be called directly to cherry-pick a change (or commit if sourceChange is
 * null) with a few other parameters that are especially useful for cherry-picking a commit that
 * is the revert-of another change.
 *
 * @param sourceChange Change to cherry pick. Can be null, and then the function will only cherry
 *     pick a commit.
 * @param project Project name
 * @param sourceCommit Id of the commit to be cherry picked.
 * @param input Input object for different configurations of cherry pick.
 * @param dest Destination branch for the cherry pick.
 * @param timestamp the current timestamp.
 * @param revertedChange The id of the change that is reverted. This is used for the "revertOf"
 *     field to mark the created cherry pick change as "revertOf" the original change that was
 *     reverted.
 * @param changeIdForNewChange The Change-Id that the new change of the cherry pick will have.
 * @param idForNewChange The ID that the new change of the cherry pick will have. If provided and
 *     the cherry-pick doesn't result in creating a new change, then
 *     InvalidChangeOperationException is thrown.
 * @return Result object that describes the cherry pick.
 * @throws IOException Unable to open repository or read from the database.
 * @throws InvalidChangeOperationException Parent or branch don't exist, or two changes with same
 *     key exist in the branch. Also thrown when idForNewChange is not null but cherry-pick only
 *     creates a new patchset rather than a new change.
 * @throws UpdateException Problem updating the database using batchUpdateFactory.
 * @throws RestApiException Error such as invalid SHA1
 * @throws ConfigInvalidException Can't find account to notify.
 * @throws NoSuchProjectException Can't find project state.
