Is the latest version of antlr4 compatible with jdk8 jar?

[melin]

Many big data components depend on antlr4. For example: spark, antlr4 cannot be upgraded to the latest version for compatibility with jdk8.

grammars-v4 some grammars in 4.10 later, unable to upgrade the JDK version, lead to cannot use: for example: https://github.com/antlr/grammars-v4/commits/master/sql/tsql/

Is the latest version of antlr4 compatible with jdk8 jar?

Antlr runtime is compatible with jdk8. Antlr tool requires jdk11. Can you provide a concrete example of this Spark incompatibility (stack trace) ?

jdk switch to 11, ready to compile. Thanks!
jdk8 is used a lot, which is not very convenient，For example, spark antlr4 can only be upgraded to 4.9.3
apache/spark#37814

Do you mean we can using Java 11 and Antlr tool to generate java file from .g4 file, and then using Java 8+Antlr runtime to use java file at runtime?

The stack trace below is not a Jdk issue.Rather there is a mismatch between the antlr version used to generate the parser and the runtime Envoyé de mon iPhoneLe 23 mars 2023 à 11:19, melin ***@***.***> a écrit : Antlr runtime is compatible with jdk8.

Why does Antlr tool need at least jdk11? This requires that mvn requires jdk11 to run

Just set MVN_HOME ?Envoyé de mon iPhoneLe 25 mars 2023 à 15:58, melin ***@***.***> a écrit : Why does Antlr tool need at least jdk11?
