Java annotation processing: how do I know that a round is the last?

When abstractprocessor is extended, it is possible to override init (...), but there is no "opposite" method, which will be called after all rounds are processed

This is a problem: when you have to append the information collected in each round to the same file, you cannot close the file because your last round is not known Therefore, the file is never closed and remains empty

Using Shutdown hook also doesn't work. Hooks are never called

Any ideas?

Solution

Processor. The process method includes a parameter of type roundenvironment Maybe roundenvironment The processingover method can help
