Investigate failed Sonarqube builds

[fzhao99]

Description

Sonarcube seems to be intermittently failing to build in CI jobs. See examples here and here

Steps to reproduce

1. Open a PR
2. Sonar will try building but fail with the following error code

> Your project contains .java files, please provide compiled classes with sonar.java.binaries property, or exclude them from the analysis with sonar.exclusions property.

Kicking the job seems to fix it somehow, so wondering if it's just an issue on first creation?

Expected behavior

Sonar building on the first try when unrelated code is put up for review

@shanice-skylight I seem to be able to repro this pretty consistently when I'm manually rerunning the sonar job, even after the first build succeeded. See this PR for an example

Notes on why this error is triggered:

• Compiled .class files are required for java projects with more than one java file. If not provided properly, analysis will fail with the message:

Your project contains .java files, please provide compiled classes with sonar.java.binaries property, or exclude them from the analysis with sonar.exclusions property. Reference used

I added the sonar.java.binaries property, now I'm working through fixing a message that says Could not calculate hash for class, fixed the hash error by providing the full path to java classes
