Build and install nodes

This section explains how to build and install authentication nodes for use in authentication trees.

Build and install a custom authentication node

Change to the root directory of the Maven project of the custom nodes.

For example:
```
$ cd /Users/Forgerock/Repositories/am-external/openam-auth-trees/auth-nodes
```
Run the mvn clean package command.

The project will generate a .jar file containing your custom nodes. For example, auth-nodes-version.jar.

Include the custom .jar file in the AM .war file, as described in Customize the AM WAR file.

Delete or overwrite older versions of the nodes .jar file from the WEB-INF/lib/ folder, to avoid clashes.

If you are using custom nodes with version 0.0.0 in trees, you must remove them from the trees before restarting AM and reinsert them after the restart. If you do not do this, the entire tree cannot be viewed in the UI after the restart.

Restart AM for the new nodes to become available.

The custom authentication node is now available in the tree designer to add to authentication trees:

For more information on using the tree designer to manage authentication trees, refer to Configure authentication trees.

For information on upgrading custom nodes, refer to Upgrade nodes and change node configuration.
