Spring Tool Suite 4 Error

After installing the SonarLint plugin for Eclipse IDE from Marketplace and restarting the IDE I get the error message, see below, when trying to analyze file(s) in the project. I am new to the SonarLint and not sure how to proceed, any help would be welcomed.

Hi @JKBishop

For some reason your Java classpath seems to contain a file that is not readable.

Could you please enable verbose output in the SonarLint console, and look for the value of the property sonar.java.libraries or sonar.java.binaries for any file located in C:\Users<<user_name>>\AppData\Local\Application Data and see why this file is part of your classpath, and why the STS process is not allowed to access it (maybe an anti-virus software?).

Thanks you for the reply. I enabled the verbose output in the SonarLint Console and te …AppData\Local\Application Data does not show up in the sonar.java.libraries list and yet I still get the error message. I did search the Eclipse project, all files, and there is no reference to that directory yet SonarLint is trying to search it. Any ideas why?
