[Discuss] Provide command to rerun the CI

[kun-song]

For now, the CI seems unstable and sometimes it failed, and it will succeed after a rebuild. I have encoutered this problem several times, and so as some other contributor(#3389).

Do we have or should we have any command to start a rebuild?

Currently only committer has the permission to trigger the re-build.
I think what we can do for now is:

• identify why is the UT unstable and fix it
• contributors can request any of the committers to trigger it manually or asking on the mail list for help.

Can @dubbo-bot help in this situation? What I mean is that if dubbo-bot can trigger the rebuild task, we can do something like this:

Mention dubbo-bot in the comment, such as:

@dubbo-bot test this please

or something like this. Then @dubbo-bot can trigger the build task, this may need more investigation in travis-ci and the GitHub hooks

I wish it could.

In fact, dubbo-bot does not have the permission to trigger the build, either. :(
To trigger the build, a write access to the repo is needed.

If you want to trigger it manually without letting the committers to know, you can commit an empty message.

@ralf0131 Yes that's what I've done in #3389

Before you do that, it is better to save the error log, and report to the community to investigate.

Sounds reasonable, committers can trigger it manually and contributors can trigger by an empty commit, that's what I want. Thanks @ralf0131 :)
