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:
    Comparable<Task>, org.gradle.api.internal.DynamicObjectAware, org.gradle.api.internal.IConventionAware, org.gradle.api.internal.TaskInternal, ExtensionAware, Task, PatternFilterable, org.gradle.util.Configurable<Task>

      @CacheableTask
      public 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:

       apply plugin: 'java'

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

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

       apply plugin: '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")
       }

          @PathSensitive(value=RELATIVE)
          public FileTree getSource()

      Returns the source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.
      Overrides:
        `getSource` in class `SourceTask`
      Returns:
        The source.

    - #### getToolChain

          @Incubating
          @Inject
          public JavaToolChain getToolChain()

      Returns the tool chain that will be used to generate the Javadoc.

    - #### setToolChain

          @Incubating
          public void setToolChain(JavaToolChain toolChain)

      Sets the tool chain to use to generate the Javadoc.

    - #### getDestinationDir

          @Internal
          public File getDestinationDir()

      Returns the directory to generate the documentation into.

      Returns:
        The directory.

    - #### getOutputDirectory

          @OutputDirectory
          protected File getOutputDirectory()

    - #### setDestinationDir

          public void setDestinationDir(File destinationDir)
