Update jacoco to latest release v0.8.0

[shobhitagarwal1612]

Some of the unit tests were not getting included in the code coverage report due to some bug in the old jacoco version that we were using. The latest version v0.8.0 is supposed to fix all that issue.

For eg. Validator.java is 100% covered but in codecov it displays 0%.

What has been done to verify that this works as intended?

Tried running the report locally for unit tests and the code coverage increased as expected (Validator file showing 100% coverage and many others)

Why is this the best possible solution? Were any other approaches considered?

Tried approaching the firebase-community and they suggest this as one of the possible solutions

Are there any risks to merging this code? If so, what are they?

Before merging, we need to ensure that the file generated by
firebase is also of the same version so that the report can be properly generated.

Do we need any specific form for testing your changes? If so, please attach one.

no

Heya @shobhitagarwal1612! The reason for the downgrade was to be able to work with Firebase. Do you have any new information that suggests they've upgraded?

[shobhitagarwal1612]

@lognaturel I have updated the description for the PR

@lognaturel Should I remove the master filter from circle-ci config and try to rebuild the branch just to ensure if everything works fine? I'll revert it back after that

Seems Firebase continues to generate 0x1006 files. If it didn't, the current report would fail, right?

Great idea to reach out to the firebase community. Do you want to link that post here for future reference?

I used the slack channel. Can that be linked?

It works !!! Check out this link
The code coverage increased to 28%

@lognaturel I've cleaned the commits and removed unncessary changes

Well isn't that great! Thanks, @shobhitagarwal1612!! Mysterious that 0.7.9 didn't work... but oh well!
