Visit https://spring.io/tools This product includes software developed by the Eclipse Foundation https://www.eclipse.org This product includes software developed by the Apache Software Foundation https://www.apache.org Lombok v1.18.12 "Envious Ferret" is installed. https://projectlombok.org/ I have the same problem… No matter what eclipse build I find myself using, it seems to only ever take a few months and suddenly the whole workspace starts acting wonky. I really hope someday the answer isn't simply "re-install the whole app". I'm getting sick of recreating my entire environment from scratch every time Eclipse decides to break itself amidst normal usage.
