best practice: how to host server-side code in the maven repository

Question

What is the best way to put javascript/html/css code in the maven repository, so that is easily usable by java projects.

Is there a way to do it such that the included project can be easily made "web-visible" by the including project?

For example assume I write a very useful tricks.js file an put it in the mvn repository.

Is it possible to create a web project that adds tricks.js as a dependency and then doing

<script src="/some/thing/tricks.js"/>

causes the tricks.js file to be served?

Answer 1

You can pack it into jar and then unpack it by maven plugins.

Answer 2

External resources should be packaged into an artifact and published to the repository (for simplicity use a jar artifact, but you could specify an assembly to package a zip instead to make it clear what the artifact is for). The maven-dependency-plugin unpacks the jar's contents into a specified location in the war project. That folder is then specified as an external web resources directory for the maven-war-plugin.

The following configuration will unpack the contents of my-resources into the target/external-resources directory, then include the contents of that folder in the war as if they'd been defined in src/main/resources.

  <groupId>org.apache.maven.plugins</groupId>

  <executions>
    <execution>
      <id>unpack</id>
      <phase>generate-resources</phase>

      </goals>
      <configuration>

            <type>jar</type>
            <overWrite>false</overWrite>
          </artifactItem>
        </artifactItems>
        <outputDirectory>${project.build.directory}/external-resources</outputDirectory>
        <overWriteReleases>false</overWriteReleases>
      </configuration>
    </execution>
  </executions>
</plugin>
