Plugin gradle dependencies not included in plugin artifact

Hi,

I am working on a tool integration plugin that calls some REST APIs to internal services. This requires some dependencies like org.json et.al. which I've declared in build.gradle:

plugins {
    id 'java'
    id 'org.jetbrains.intellij' version '1.3.1'
}
group 'my.company'
version '1.0.0-SNAPSHOT'
dependencies {
    implementation 'org.json:json:20211205'
    implementation 'io.socket:engine.io-client:2.0.0'
    implementation 'com.miglayout:miglayout-swing:11.0'
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.8.1'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.8.1'
}
intellij {
    version = '2021.3.2'
}
patchPluginXml {
    version = project.version
    sinceBuild = '211'
    untilBuild = '213.*'
    changeNotes = """..."""
}
buildSearchableOptions {
    enabled = false
}

test {
    useJUnitPlatform()
}
