Create Jar from Checker Framework enabled build?

I'm adding Checker Framework to an existing Java Gradle build. I have Checker integrated and raising issues and that's all working great. But now that I've added it, my build is no longer producing a .jar file as it once did.

Previously, I'd get a .jar at build/libs/myproject.jar. Now instead I see build/checkerframework and build/main but no build/libs and no .jar.

My build.gradle is below. Anyone attempted this before? Any success?

I guess I'd also accept an answer that shows how run Checker outside of the build, e.g. gradle check to run a build with Checker, and gradle build to produce a .jar. But I'd really prefer to have just a single build step if at all possible.

Thanks!

plugins {
    id "org.checkerframework" version "0.5.18"
    id 'application'
}

apply plugin: 'org.checkerframework'

checkerFramework {
    checkers = [
        'org.checkerframework.checker.nullness.NullnessChecker',
        'org.checkerframework.checker.units.UnitsChecker'
    ]
}

repositories {
    jcenter()
}

java {
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}

jar {
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE

    // Embed all dependencies to create a "fat jar" as required for AWS deployment.
    // Exclude 3rd-party signing files to prevent security errors at runtime
    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    } {
        exclude 'META-INF/*.RSA', 'META-INF/*.SF', 'META-INF/*.DSA'
    }

    manifest {
        attributes('Main-Class': 'client.CliMain')
    }
}

If the build is passing, then adding -processor should not affect whether a .jar file is produced. (Unless you pass -proc:only or the like.)

If the build is failing, then Gradle won't build the jar files. You said the Checker Framework is "raising issues", so maybe the build is failing.
