I just tried to send a Maven-based project to another computer and HORROR, red markers everywhere!!
However, mvn clean install is building just fine.
When using lombok on a fresh installation of Eclipse or STS, you have to:
Install the lombok jar which you can get at https://projectlombok.org/download. Run the jar (as Administrator if using windows) and specify the path to your Eclipse/STS installation.
Restart your IDE (Eclipse or STS)
Give some time for eclipse to generate the class files for lombok (Might take a up to 4 mins in some cases)
