Fix maven JSTL 1.2.1 dependency so maven-war-plugin doesn't package JARs that offend Tomcat 7

Question

My setup: jdk 7, Tomcat 7.0.29, ,Eclipse Juno (with m2e[Maven 3.0.4 embedded], m2eclipse-wtp)

I have a Dynamic Web Project with this JSTL dependency:

Answer 1

Figured it out, the jsp-api was sneaking into the WEB-INF\lib as a transative dependency of the jstl, the fix is to exclude like so.

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>javax.servlet.jsp.jstl</artifactId>
    <version>${javax.jstl.version}</version>
    <exclusions>
        <exclusion>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
        </exclusion>
        <exclusion>
            <artifactId>jsp-api</artifactId>
            <groupId>javax.servlet.jsp</groupId>
        </exclusion>
    </exclusions>
</dependency>

Answer 2

For version 1.2.1 use:

<!-- add the selvlet-api that tomcat provides as provided -->
<dependency>
    <groupId>javax.servlet.jsp.jstl</groupId>
    <artifactId>javax.servlet.jsp.jstl-api</artifactId>
    <version>1.2.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>javax.servlet.jsp.jstl</artifactId>
    <version>1.2.1</version>
    <exclusions>
         <!-- jstl-api was adding selvlet-api 2.5 and jsp-api-->
        <exclusion>
            <artifactId>jstl-api</artifactId>
            <groupId>javax.servlet.jsp.jstl</groupId>
        </exclusion>
    </exclusions>
</dependency>

Because if not the jstl-api 1.2 will be added as a dependency. It is the jstl-api that added the jsp-api and servlet-api dependencies.
