Version: 7.9.5  
My coverage reports are spiking high and low. For example each time sonar builds coverage report the % of code covered will be in the 80% then when i build again it unexpectedly drops to 30%. If i build again a few more times it jumps back to 80%. And so on so forth. This happens even if there is no code change, I’ve exhausted everything that i can try. Hoping someone here can help me figure out why it is spiking.

Hey there.

First of all – you should know that SonarQube _v7.9 LTS_ is an EOL version of SonarQube. You should upgrade to at least _v8.9 LTS_ at the earliest.

I would suggest checking your build/scanner logs and making sure that between runs (one high, one low):

- A full rebuild of your code is taking place
- The number of successful tests are the same (example for Maven)

```auto

T E S T S

-------------------------------------------------------

Running com.acme.basic.HelloWorldTest

Hello World!

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.043 sec

Results :

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

```

- The number of indexed files are the same (scanner logs)

`INFO: 15 files indexed`

If it doesn’t become obvious where the issue is, try upgrading to _v8.9 LTS_ and come back so we can provide more help.

Thank you,  
I’ll check those three and hopefully that reveals it self.
