For the maven multi-module project built by idea, jsp, will not be updated when tomcat starts. Will jsp take effect only after maven install is required?

Artifacts has been set to war exploded, and tomcat has been set to
clipboard.png
but jsp is still not updated automatically, and it is useless for
to restart tomcat.
will only take effect after maven install&compile, but this development is too inefficient.
have you ever encountered similar problems?

is now in use of jsp.
jsp is automatically recompiled as soon as it is changed. It does not work because it is not copied to the application directory of Tomcat. I usually use the maven-resources-plugin plug-in implementation of maven to copy related files to tomcat,. This plug-in behavior I bind to valadate, this is the first command in the maven life cycle, and the execution step is relatively fast
