Gradle XJC generate equals and hashCode methods

The project has a gradle module to build JAX2B classes. The XJC configuration already uses annotations:

    bindingFiles = project.files("$projectDir/src/main/resources/binding.xjb",
      "$projectDir/src/main/resources/annotations.xjb")
    // Needed to execute custom annotations
    options.add("-Xannotate")
}

I thought I could add options to get equals() and hashCode()

xjc {
    bindingFiles = project.files("$projectDir/src/main/resources/binding.xjb",
      "$projectDir/src/main/resources/annotations.xjb")
    options.addAll("-Xannotate", "-Xequals", "-XhashCode")
}

The methods are not on the class and there are no errors or warnings in the build log. How do I generate those methods?

PS: Here are the build file dependencies

dependencies {
    implementation(project(":xxx:xxx-api"))
    implementation("com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.11.2")
    xjcPlugins("com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.11.2")
    xjcPlugins("org.jvnet.jaxb2_commons:jaxb2-basics-annotate:1.1.0")
}

Thanks to @thokuest for spotting a missing dependency.

The project has a gradle module to build JAX2B classes, but I'm getting build errors adding the "-Xequals" option:

build/generated/sources/xjc/java/org/pen/ProductOutputType.java:16: error: package org.jvnet.jaxb2_commons.locator.util does not exist
import org.jvnet.jaxb2_commons.locator.util.LocatorUtils;
                                           ^
build/generated/sources/xjc/java/org/pen/ProductOutputType.java:47: error: cannot find symbol
public class ProductOutputType implements Equals2
                                         ^

I've created a minimum example as a gist -- build.gradle.kts

gradle xjc jaxb java

equals() and hashCode() are contributed by the jaxb2-basics plugin.

xjcPlugins 'org.jvnet.jaxb2_commons:jaxb2-basics:1.11.1'

According to the project's wiki, there's a runtime dependency to org.jvnet.jaxb2_commons:jaxb2-basics-runtime:1.11.1 that you would need to add as well.

Update

Dependency org.jvnet.jaxb2_commons:jaxb2-basics-runtime:1.11.1 must be in scope implementation as otherwise a build error as described in the question occurs.
