Package org.gradle.api.tasks.javadoc

## Class Javadoc

- java.lang.Object
- - org.gradle.api.internal.AbstractTask
  - - org.gradle.api.DefaultTask
    - - org.gradle.api.internal.ConventionTask
      - - org.gradle.api.tasks.SourceTask
        - - org.gradle.api.tasks.javadoc.Javadoc

- All Implemented Interfaces:
    `java.lang.Comparable<Task>`, `org.gradle.api.internal.DynamicObjectAware`, `org.gradle.api.internal.IConventionAware`, `org.gradle.api.internal.TaskInternal`, `Named`, `ExtensionAware`, `Task`, `PatternFilterable`, `Configurable<Task>`

      @CacheableTask
      public abstract class Javadoc
      extends SourceTask

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

      Returns the source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

      The `PathSensitivity` for the sources is configured to be `PathSensitivity.ABSOLUTE`. If your sources are less strict, please change it accordingly by overriding this method in your subclass.

    - #### isVerbose

          @Deprecated
          @Internal
          public boolean isVerbose()

      This method duplicates the functionality of `getOptions().verbose()`. It will be removed in Gradle 9.0.
      Sets whether Javadoc generation is accompanied by verbose output or not. The verbose output is done via println (by the underlying Ant task). Thus it is not handled by our logging.
      Parameters:
