Eclipse STS 4 Error: Could not find or load main class

Question

I got following error on my latest version of Eclipse STS 4.

Could not find or load main class com.infoflow.report.ReportApplication

here is my STS Version:

Spring Tool Suite 4
Version: 4.5.1.RELEASE

Build Id: 202001211336

My Spring Version

2.0.6.RELEASE

I have tried following actions but seem no luck yet:

1. Re-Import the Project
2. Maven Clean / Project Clean
3. Change the JRE to JDK
4. List item

Any help regarding this would be very appreciated.
