# Javadoc

@CacheableTask
abstract class Javadoc : SourceTask(source)

Generates HTML API documentation for Java classes.

If you create your own Javadoc tasks remember to specify the 'source' property! Without source the Javadoc task will not create any documentation. Example:

    plugins {
        id 'java'
    }

    task myJavadocs(type: Javadoc) {
      source = sourceSets.main.allJava
    }

An example how to create a task that runs a custom doclet implementation:

    plugins {
        id 'java'
    }

    configurations {
      jaxDoclet
    }

    dependencies {
      // jaxDoclet "some.interesting:Dependency:1.0"
    }

    task generateRestApiDocs(type: Javadoc) {
      source = sourceSets.main.allJava

      options.docletpath = configurations.jaxDoclet.files.asType(List)
      options.doclet = "com.lunatech.doclets.jax.jaxrs.JAXRSDoclet"
      options.addStringOption("jaxrscontext", "http://localhost:8080/myapp")
    }
