Javadoc plugin using maven central only vs defined repositories

I have some snapshot artifacts deployed to Sonatype that I’d like to perform some verification against, however, when attempting to build the javadocs, Gradle is only searching Maven central vs the defined Sonatype repository - the build itself is fine.

Here’s the error:

> Could not resolve all files for configuration ':javadocAggregatorClasspath'.
   > Could not find com.oracle.coherence.ce:coherence-bom:22.06-SNAPSHOT.
     Searched in the following locations:
       - https://repo.maven.apache.org/maven2/com/oracle/coherence/ce/coherence-bom/22.06-SNAPSHOT/maven-metadata.xml
       - https://repo.maven.apache.org/maven2/com/oracle/coherence/ce/coherence-bom/22.06-SNAPSHOT/coherence-bom-22.06-SNAPSHOT.pom

The build script:

buildscript {
    repositories {
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath "io.micronaut.build.internal:micronaut-gradle-plugins:5.3.10"
    }
}

subprojects { Project subproject ->
    group "io.micronaut.coherence"
    ext {
        micronautVersion = '3.5.2'
    }
    repositories {
        //jcenter()
        mavenCentral()
        maven { url "https://s01.oss.sonatype.org/content/repositories/snapshots/" }
        maven {
            url "https://oss.sonatype.org/content/repositories/snapshots"
            mavenContent {
                snapshotsOnly()
            }
        }
        maven { url "https://oss.sonatype.org/content/groups/staging" }
        mavenLocal()
    }
...

That has nothing to do with the built-in plugin. This JavaDoc aggregation is done by io.micronaut.build.docs.JavadocAggregatorPlugin, so without more information it is hard to tell anything. Maybe you should ask the maintainer of that plugin.
