how can i use it with gradle?

[raul-sr]

What do I need to apply it in gradle?

[el-hult]

My attempt is

apply plugin: 'java'

repositories {
    mavenCentral()
    maven {url "https://jitpack.io"}
}
configurations {
    pumldoclet
}
dependencies {
    pumldoclet 'com.github.gboersma:uml-java-doclet:1.1'
}

javadoc {
    options.doclet = 'info.leadinglight.umljavadoclet.UmlJavaDoclet'
    options.docletpath = configurations.pumldoclet.files.toList()
}

but I cannot get it to run, since I have JDK 11, and this tool only works with JDK 8.

Please let me know if you have any luck making it run.

There is an alternative plantuml-taglet with following syntax:

/**
 * Description.
 *
 * <img src="example.svg">
 *
 * This package/class ...
 *
 * @plantUml example.svg
 * Alice -> Bob: Authentication Request
 * Alice <-- Bob: Authentication Response
 * 
 */

Result:
