Commit Messages and it's Validation

anil kumar42

Hi All,

I want to apply some validation on commit message.

How can I achieve this.

I got one sample in github i.e., https://github.com/sford/yet-another-commit-checker

there they used for jira services so I thought it not suited for my requirement because some of the classes I'm not able to import.

I'm using stash server and atlas-sdk. created pre repository hook. and I modified for getting commit message like below in my class.

public class MyPreReceiveRepositoryHook implements PreReceiveRepositoryHook
{

private CommitService commitService;

public MyPreReceiveRepositoryHook(CommitService commitService) {
this.commitService = commitService;
}

public boolean onReceive(RepositoryHookContext context, Collection<RefChange> refChanges, HookResponse hookResponse)
{

final ChangesetsBetweenRequest request = new ChangesetsBetweenRequest.Builder(context.getRepository()) .exclude(((RefChange)refChanges).getFromHash()).include(((RefChange)refChanges).getToHash()) .build();

final Page<Changeset> cs = commitService.getChangesetsBetween(request, new PageRequestImpl(0, PageRequest.MAX_PAGE_LIMIT));

String commitMessage;

for(Changeset changeset: cs.getValues())
{
commitMessage = changeset.getMessage();

hookResponse.out().println(commitMessage);
}

return true;
}
}

With this I want to see the commit messages but I got this error on Git(client console).

remote: Hook com.konylabs.stash.plugin.hook.MyPreReceiveRepositoryHook failed. Error:
remote: com.google.common.collect.SingletonImmutableList cannot be cast to com.atlassian.stash.repository.RefChange

Regards

The reason for getting the exception is that here:
final ChangesetsBetweenRequest request = new ChangesetsBetweenRequest.Builder(context.getRepository()) .exclude(((RefChange)refChanges).getFromHash()).include(((RefChange)refChanges).getToHash()) .build();
You try to cast a Collection<RefChange> to a single RefChange.

Instead, you need to iterate over the collection like this:

for(RefChange refChange: refChanges)
{
	ChangesetsBetweenRequest request = new ChangesetsBetweenRequest
		.Builder(context.getRepository())
		.exclude(refChange.getFromHash())
		.include(refChange.getToHash()).build();
	[do the rest of the stuff here]
}
