Field Details

baseline

@CheckForNull
public final SCMRevisionState baseline

Baseline of the comparison. (This comes from either the workspace, or from the remote repository as of the last polling. Can be null.

remote

@CheckForNull
public final SCMRevisionState remote

Current state of the remote repository. To be passed to the next invocation of the polling method. Can be null.

change

@NonNull
public final PollingResult.Change change

Degree of the change between baseline and remote. Never null.

The fact that this field is independent from baseline and remote are used to (1) allow the incomparable state which forces the immediate rebuild, and (2) allow SCM to ignore some changes in the repository to implement exclusion feature.

NO_CHANGES

public static final PollingResult NO_CHANGES

Constant to indicate no changes in the remote repository.

SIGNIFICANT

public static final PollingResult SIGNIFICANT

BUILD_NOW

public static final PollingResult BUILD_NOW

Constant that uses PollingResult.Change.INCOMPARABLE which forces an immediate build.
