Adding the JSON service registry feature requires adding a new dependency to the Maven project object model and rebuilding the server.

Add the JSON service registry to the project object model

To add JSON service registry support to the CAS server, edit the file pom.xml in the cas-overlay-template directory on the master build server (casdev-master) and locate the dependencies section (around line 69), which should look something like this:

<dependencies>
    <dependency>
        <groupId>org.apereo.cas</groupId>
        <artifactId>cas-server-webapp${app.server}</artifactId>
        <version>${cas.version}</version>
        <type>war</type>
        <scope>runtime</scope>
    </dependency>
</dependencies>

Insert a new dependency for the JSON service registry:

<dependencies>
    <dependency>
        <groupId>org.apereo.cas</groupId>
        <artifactId>cas-server-webapp${app.server}</artifactId>
        <version>${cas.version}</version>
        <type>war</type>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.apereo.cas</groupId>
        <artifactId>cas-server-support-json-service-registry</artifactId>
        <version>${cas.version}</version>
    </dependency>
</dependencies>

Rebuild the server

Run Maven again to rebuild the server according to the new model:

casdev-master# ./mvnw clean package
