how to debug Encountered " "|" "| "" at line 129, column 43.

[thetoaster]

what should I do, if Roo stopped working and only returns:

roo> Encountered " "|" "| "" at line 129, column 43.
Was expecting one of:
    <IDENTIFIER> ...
    "..." ...

I have no clue which file should have some error in it. I have no compile errors, but Roo is not working.
thanks for any advice!

seems multi-catch is not working with spring roo, see my reported error https://jira.springsource.org/browse/ROO-3314

but it would still be interesting on how to find such errors, resp. the place they occur, instead of needing a bash-file to grab all files!

Yeah, I've also encountered this error with multi-catch and was about to raise it in JIRA, so thanks for doing it already. Even with "development mode true" the roo shell does not output the filename where the problem occurs.

Note a similar error occurs when you have code such as "new ArrayList<>()", which roo also can't handle. We can live with that, but not the crash on multi-catch blocks. It makes roo completely unusable for us if we have to replace all multi-catches.
