in the process of using IDEA, the service is often broken or restarted. Recently, when the service is interrupted and restarted, a startup error is encountered:
error: the main class
cannot be found or loaded
guess: 1, failed to compile;
try: menu -> Build – “Rebuild Prodject p>
result: the startup service still reports the same error
2, caching problem;
try: menu — “File–” Invalidate Caches/Restart select Invalidate and Restart or just Invalidate, clear the cache, and then Rebuild Project
results: start successfully, problem solving
