IntelliJ: Exception in Plugin - NullPointerException #618

Closed MartinHaeusler closed 1 year ago

MartinHaeusler commented 1 year ago

The following happened to me today while using the ANTLR plugin. Sorry, I've found it at the end of a lengthy session in my IntelliJ logs, I don't know exactly how/when that happened.

IntelliJ version: 2022.3.1 (Community Edition) ANTLR Plugin version: 1.19.3-3

Stack Trace:

GenerateLexerRulesForLiteralsAction#update@EditorPopup (org.antlr.intellij.plugin.actions.GenerateLexerRulesForLiteralsAction), actionId=antlr.DefineLexerRulesForLiterals, text='Generate lexer rules for literals'

OpenSuse tumbleweed.

Only happens on some input files (with the same grammar) and happens after re-install

I switched to using ANTLR4IDE plugin for eclipse. It has its own issues and is far from perfect, but at least it works. https://github.com/antlr4ide/antlr4ide
