Method Detail

call

public RevCommit call()
               throws GitAPIException,
                      NoHeadException,
                      NoMessageException,
                      UnmergedPathsException,
                      ConcurrentRefUpdateException,
                      WrongRepositoryStateException,
                      AbortedByHookException

Executes the commit command with all the options and parameters collected by the setter methods of this class. Each instance of this class should only be used for one invocation of the command (means: one call to call())

Specified by:

call in interface Callable<RevCommit>

Specified by:

call in class GitCommand<RevCommit>

Returns:

a RevCommit object representing the successful commit.

Throws:

NoHeadException - when called on a git repo without a HEAD reference

NoMessageException - when called without specifying a commit message

UnmergedPathsException - when the current index contained unmerged paths (conflicts)

ConcurrentRefUpdateException - when HEAD or branch ref is updated concurrently by someone else

WrongRepositoryStateException - when repository is not in the right state for committing

AbortedByHookException - if there are either pre-commit or commit-msg hooks present in the repository and one of them rejects the commit.

GitAPIException - or subclass thereof when an error occurs

setMessage

public CommitCommand setMessage(String message)

Parameters:

message - the commit message used for the commit

Returns:

this

setAllowEmpty

public CommitCommand setAllowEmpty(boolean allowEmpty)

Parameters:

allowEmpty - whether it should be allowed to create a commit which has the same tree as it's sole predecessor (a commit which doesn't change anything). By default when creating standard commits (without specifying paths) JGit allows to create such commits. When this flag is set to false an attempt to create an "empty" standard commit will lead to an EmptyCommitException.

By default when creating a commit containing only specified paths an attempt to create an empty commit leads to a JGitInternalException. By setting this flag to true this exception will not be thrown.

Returns:

this

Since:

4.2
