Add code coverage in codecov

[taojintianxia]

as we could see on https://app.codecov.io/gh/apache/shardingsphere there have been no code coverage updates in the last three months, please add the code coverage in codecov.io.

I am assuming update the coverage need an access to the project in codecov and it could not be accessed without being part of the organization (apache) or contributor to this repo ?

If we dont need extra access for this, maybe I can pick this up since it sounds pretty straightforward to me.

Hi @taojintianxia , I know you are busy, so I make another comment here to increase visibility.

Please feel free to let me know if I could pick up this task and if I need extra permission to update the coverage icon.

Thank you!

Further investgation pointed out that if any maintainer of this repo could access repo settings > secrets and variable > actions and properly set the variable of CODECOV_TOKEN=EXAMPLE

I could make the following steps in the nightly-check.yml or other CI you proposed to enable this feature

- name: Upload coverage reports to Codecov
  uses: codecov/codecov-action@v3
  env:
    CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}

there is no settings for the Apache project since all the settings are maintained by apache infra team. we have to raise up an Apache Ticket to apache infra team.

and as I can see, it will not take an effect if only add the upload codecov action, let me explain this to you : Codecov is a webiste to show the code coverage for a repository, but codecov itself will not execute any test and generate the code coverage, it just read the test report from a repository. the most popular report is jacoco report, whenever we launch up a test task, generate the jacoco report and then upload that report to codecov, after that , codecov read and parse then show the code coverage on it's website.this is the correct process.

however after we upgrade the test to Junit 5, it will not generate jacoco report correctly, that's the reason codecov disply nothing.

and, BTW, I read the document for codecov action several month ago, I remember the public repositoy does not need the token

@Zhenye-Na I have a suggestion, you could fork the shardingsphere project and test the action for you own fork, cause in your fork repository, you have the permission to modify settings. ^_^

[Zhenye-Na]

I see. Thanks for the explanation, I always forget that I have my own fork which could be used to test things out.

Let me get back to you and publish a PR if I find the way to solve this
