The Jetty Maven plugin with the scanIntervalSeconds
configuration set to a positive value performs complete application restart when the given number of seconds have elapsed since the last Java change.
For instance:
<plugins>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.4.36.v20210114</version>
<configuration>
<scanIntervalSeconds>2</scanIntervalSeconds>
</configuration>
</plugin>

Since the plugin performs a full server restart, all Java changes are picked up.
This includes modifications to server startup listeners, as well as changes to code that connects front-end and back-end components, such as adding a new LitTemplate
class, or adding a new CSS import and using it in Java via the @CssImport
annotation.
However, the session isn’t preserved during the restart.
