Prerequis : common usages

Configuration

to generate apidocs / scaladoc for your scala sources, add this to your pom.xml

with maven 2.x

<project>
  ...
  <reporting>
    <plugins>
      ...
      <plugin>
        <groupId>org.scala-tools</groupId>
        <artifactId>maven-scala-plugin</artifactId>
      </plugin>
      ...
    </plugins>
  </reporting>
  ...
</project>

with maven 3.x

<project>
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-site-plugin</artifactId>

To generate api

Place scala sources files in : 

src/main/scala

Then use the standard maven phases : 

          
# generate a site
mvn site

Or the plugin specifics goal : 

          
# generate only the doc
mvn scala:doc

See the result under target/site/scaladocs/

To use a custom api generator

You need to declare the main class to call (with the same parameter as scaladoc). And you need to list the additional artifact(jar) to use : 

<configuration>
  <scaladocClassName>org.scala_tools.vscaladoc.Main</scaladocClassName>
  <scalaJars>
    <scalaJar>
      <groupId>org.scala-tools</groupId>
      <artifactId>vscaladoc</artifactId>
      <version>1.0</version>
    </scalaJar>
  </scalaJars>
</configuration>

Then use the standard maven phases : 

          
# generate a site
mvn site
# or generate only the doc
mvn scala:doc

See the result under target/site/scaladocs/

To use vscaladoc

vscaladoc have a shortcut way to use it (instead of using the custom way describe above) : 

<configuration>
  <vscalaVersion>1.0</vscalaVersion>
</configuration>

Then use the standard maven phases : 

          
# generate a site
mvn site
# or generate only the doc
mvn scala:doc

See the result under target/site/scaladocs/
