The plugin uses Java2Html Ant task to convert Java (and other) source code (complete files or snippets) to HTML, RTF, TeX and XHTML with syntax highlighting. The task is only available to projects that apply the Java or Groovy plugin.

To use the Java2HTML plugin, include in your build script:

apply plugin: 'com.bmuschko.java2html'

The plugin JAR needs to be defined in the classpath of your build script. It is directly available on Bintray. Alternatively, you can download it from GitHub and deploy it to your local repository. The following code snippet shows an example on how to retrieve it from Bintray:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.bmuschko:gradle-java2html-plugin:2.0.1'
    }
}

To define the Java2HTML dependency please use the java2html configuration name in your dependencies closure.

dependencies {
    java2html 'de.java2html:java2html:5.0'
}

The Java2HTML plugin defines the following tasks:

• java2htmlConvertCode: Converts source code files to Java2HTML documentation.
• java2htmlGenerateOverview: Generates HTML overview files for Java2HTML documentation.

The Java2HTML plugin defines the following convention properties in the java2html closure. This closure itself contains two closures for each of the tasks: conversion and overview.

In the closure conversion you can define property values for converting the source code:

• srcDirs: Source directories to look for source code files for conversion (defaults to file('src/main/java') for a Java project and to files('src/main/java', 'src/main/groovy') for a Groovy project).
• destDir: Destination folder for output of the converted files (defaults to file('build/docs/java2html')).
• includes: File mask for input files (defaults to **/*.java,**/*.groovy).
• outputFormat: File format for conversion output (defaults to html). Valid values are html, xhtml11, xhtml, tex, rtf and xml.
• tabs: Width in spaces for a tab character (defaults to 2).
• style: Sets the table name for the output style (defaults to eclipse). Valid values are eclipse, kawa and monochrome.
• showLineNumbers: Show line numbers in conversion output (defaults to true).
• showFileName: Show the file name in conversion output (defaults to false).
• showDefaultTitle: Sets the title of generated html pages (if any) to the relative name of the source file, e.g. de/java2html/Java2Html.java (defaults to empty false).
• showTableBorder: Show a border around the conversion output (defaults to false).
• includeDocumentHeader: Add a document header at the beginning of the output file (defaults to true).
• includeDocumentFooter: Add a document footer at the end of the output file (defaults to true).
• addLineAnchors: Add html-anchors to each line for html output (defaults to false).
• lineAnchorPrefix: String that will be added as prefix for the line anchors for html output (defaults to '').
• horizontalAlignment: Horizontal alignment of the output (defaults to left). Valid values are left, center and right.
• useShortFileName: Use short (ClassName.html) or long (ClassName.java.html) filenames for output (defaults to false).
• overwrite: Overwrite existing files even if the destination files are newer (defaults to false).

In the closure overview you can define property values for generating the HTML overview files:

• srcDirs: Source directories to look for generated files by Java2HTML (defaults to file('build/docs/java2html') of all modules in project).
• destDir: Destination folder for HTML overview files (defaults to file('build/docs/java2html')).
• pattern: Java2HTML file pattern to be included in HTML overview (defaults to **/*.html).
• windowTitle: Window title in overview (defaults to project name).
• docTitle: Document title in overview (defaults to project name).
• docDescription: Document description in overview.
• icon: Icon file to be use in overview.
• stylesheet: CSS stylesheet file to be use in overview (defaults to JavaDoc stylesheet).
