I created a simple maven project that contains a basic index.jsp file with the IDE IntelliJ IDEA
when I click on "valide index.jsp file"
I get the error:
Error:org.apache.jasper.JasperException: The -uriroot option must specify a pre-existing directory
1) what is the operation " valide index.jsp file" ?
2) that caused the error and how to fix this ?
