IntelliJ 2022.1 parser generation issue. #528

Closed hanohrs closed 2 years ago

hanohrs commented 2 years ago

Generating a parser for Hello.g4 in Getting Started with ANTLR v4 failed with a NullPointerException.

Although it says "parser for Hello.g4 generated", nothing is there.

The root cause might be the startup issue, #527.

Stacktrace:

java.lang.NullPointerException

Confirmed that this is a duplicate of #495 and fixed in the snapshot version, "https://github.com/antlr/intellij-plugin-v4/files/8192836/antlr-intellij-plugin-v4-1.18-SNAPSHOT.zip".

I'm sorry for rashly issuing. I hope to use a release version in near future.
