Dependency failure

Hi Rick,

Great presentation you did with Victor Rentea, but when I tried to also use this project I got an error from the very beginning:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.10.1:compile (default-compile) on project error-prone-demo: Resolution of annotationProcessorPath dependencies failed: Missing:
[ERROR] ----------
[ERROR] 1) com.github.PicnicSupermarket.error-prone:error_prone_core:jar:2.17.0-picnic-3
[ERROR] 
[ERROR]   Try downloading the file manually from the project website.

[ERROR]   Then, install it using the command:

[ERROR]   Alternatively, if you host your own repository you can deploy the file there:

I could not manually find the dependency on Maven repo either, nor where to manually download it from the project website. Please point me in the right direction.

Many thanks!
