Alas, this plugin is unmaintained.
Consider instead:
A Maven plugin that compiles JSPs into class files, copies these into the final artifact, and updates the web.xml to reference the compiled classes. This is a fork of the Codehaus jspc-maven-plugin that resolves some long standing issues and gets the Tomcat 7 support released.
See the Maven Project Documentation for goal documentation.
Plugin Usage is also documented on the maven site.
The available JSP compilers can be found by browsing org.jasig.mojo.jspc GroupId.
The JSPC plugin is a wrapper around Tomcat's JSP Compiler. For issues relating to JSP syntax please report the issue to tomcat. Tomcat 6 issue tracker Tomcat 7 issue tracker Tomcat 8 issue tracker
Issues relating to maven or configuration options should reported to the JSPC issue tracker
Invocation of static methods on interfaces fails with the latest minor version of every tomcat compiler below 9.x.
