Java: Can't use ANTLR 4.11.1 on Java 8

[raylras]

I am using Java 8, Gradle 7.4.2 and ANTLR 4.11.1 to develop. When I run the gradle task generateGrammarSource I got an exception:

Execution failed for task ':generateGrammarSource'.
> org/antlr/v4/Tool has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

The build.gradle file:

plugins {
    id 'java'
    id 'antlr'
}

java {
    sourceCompatibility = '1.8'
    targetCompatibility = '1.8'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.antlr:antlr4-runtime:4.11.1'
    antlr 'org.antlr:antlr4:4.11.1'
}

sourceSets {
    generated {
        java.srcDir 'generated-src/antlr/main'
    }
}

generateGrammarSource {
    maxHeapSize = '64m'
    arguments += ['-visitor', '-listener', '-long-messages']
    outputDirectory = new File(buildDir.toString() + '/generated-src/antlr/main')
}

That means that ANTLR 4.11.1 on maven central uses Java 11 to build and does not work with Java 8.
I noticed that the project readme is still marked Java 7+, so I guess this might be a build error.
I tried downgrading ANTLR to 4.9.3 and it worked fine with Java 8.

See the release notes for antlr 4.10 https://github.com/antlr/antlr4/releases/tag/4.10 starting in 4.10 antlr must be built with java 11 but can still be run on Java 8.

Everything works fine after using Java 11 SDK and setting the language level to Java 8. Problem solved, thank you.
