[FIXED] Intellij: maven clean verify: Failed to execute goal org.jasig.mojo.jspc:jspc-maven-plugin:2.0.2:compile: Failed to compile JSPS

Issue

My project POM has following plugins-

I'm using apache-maven-3.6.3 and Intellij IDE for building my project. But when executing mvn clean verify, I get the error-

Failed to execute goal org.jasig.mojo.jspc:jspc-maven-plugin:2.0.2:compile: Failed to compile JSPS

Solution

It is due to in tomcat 7 by default SKIP IDENTIFIER CHECK feature is false.

Hence supply-Dorg.apache.el.parser.SKIP_IDENTIFIER_CHECK=true as an argument while maven clean installing.

Alternatively a work around is also to use org.apache.sling jspc-maven-plugin

             <plugin>
               <groupId>org.apache.sling</groupId>
                <artifactId>jspc-maven-plugin</artifactId>
                <version>2.2.2</version>
                <executions>
                    <execution>
                        <id>compile-jsp</id>
                        <goals>
                            <goal>jspc</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
