GitHub provides an incredible feature that allows us to easily push Maven generated site to our project’s GitHub repository.
Here’s how to do it…
STEP 1: Define GitHub credential
Go to ~/.m2/settings.xml and add your GitHub username and password:-
<settings ...="">
<servers>
<server>
<id>github</id>
<username>USERNAME</username>
<password>PASSWORD</password>
</server>
</servers>
</settings>
STEP 2: Define GitHub’s site-maven-plugin
GitHub provides its own site-maven-plugin that can be used to deploy a Maven generated site to a gh-pages branch so that it can be served statically as a GitHub Project Page.
In pom.xml, add the following plugin configuration:-
<project ...="">
...
<build>
<plugins>
...
<plugin>
<groupid>com.github.github</groupid>
<artifactid>site-maven-plugin</artifactid>
<version>0.11</version>
<configuration>
<message>Creating site for ${project.version}</message>
<server>github</server>
</configuration>
<executions>
<execution>
<goals>
<goal>site</goal>
</goals>
<phase>site</phase>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
</project>
STEP 3: Define project URL
In pom.xml, define <url> tag that points to the project’s GitHub repository.
<project ...="">
<groupid>...</groupid>
<artifactid>...</artifactid>
<version>...</version>
<url>https://github.com/USERNAME/PROJECT-NAME</url>
...
</project>
If this is not defined, Maven will throw the following error when executing mvn clean site:-
Failed to execute goal com.github.github:site-maven-plugin:0.11:site
(default) on project PROJECT-NAME: No GitHub repository (owner and
name) configured -> [Help 1]
STEP 4: Generate Maven site and push to GitHub
Finally, run the following command: mvn clean site.
The generated site can be viewed from https://USERNAME.github.io/PROJECT-NAME/ .
That’s it…. very simple.
