Is there a way to deploy a jar without restarting in Tomcat 9?

I know this question has came up before here, however this is in regards to tomcat 9.

Is there anything that has changed in latest tomcat releases that allows to deploy a jar file without restarting tomcat ? We have been using tomcat 7 in our development and all developers restarting tomcat has been time consuming. Its application that has 700 java files that gets built in to a .jar file and about 1000 jsp files that rely on those .jar file, we are not using war. Can WatchedResource be used for this ?

If you are using Eclipse IDE, then you can simply use FileSync plugin to hot deploy the .class files into tomcat WEB-INF/classes folder.

Basically, you need to map YOUR_PROJECT/target/classes folder to WEB-INF/classes so that they will always be in sync.

This is what we do in our project to avoid the restarts of Tomcat because of source file changes.

You can always restart your webapp and not your Tomcat instance as long as the JAR resides in WEB-INF/lib and not in CATALINA_BASE/lib.
