We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

i fixed the "cla/google — Need a CLA for one or more commit authors" issue,
about the "The Travis CI build failed"- i don't know what is it..

[leibale]

why the CLA issue not resolve?

Looks like the commits are authored by dov_eidelman... If you authored the commits, you need to set the e-mail address to be your GitHub e-mail address. See http://stackoverflow.com/questions/3042437/change-commit-author-at-one-specific-commit for help on amending previous commits to update the true author.

now the commit are authored by "leibale" but the pull request still with "cla:no" label

Thanks @leibale! I'm going to implement this functionality in a new PR to address some styling issues. I'll ping you over when it's ready to take a look, and hopefully you can check it out and make sure it still works for you.

[leibale]

ok :)
