Although I love lombok, it gives too much problems while configuring sometimes, specially in Linux. When I was trying to install it, I was getting the following error:
On Linux, I copied lombook.jar file to STS folder. Then, I added below lines in STS.ini file
-vmargs
-Xbootclasspath/a:lombok.jar
-javaagent:lombok.jar
However it still didn't solve the issue. After starting STS with -clean it did work.
Go to the folder containing the STS file, and on the console run ./STS -clean.
