Unable to startup RESTEasy Maven project through Tomcat7 Maven plugin (ExecutionException)

I am working on a Maven Java project that uses RESTEasy 3.0.6.Final as its REST provider framework. Because this application will be deployed to AWS Elastic Beanstalk through its Tomcat 7 container, I have set up the project to use the Tomcat Maven Plugin as its local web container. I have the following relevant dependencies and plugins in my pom.xml file:

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-guice</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson2-provider</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-servlet-initializer</artifactId>
    <version>${resteasy.version}</version>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
</dependency>
...
<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <path>/</path>
    </configuration>
</plugin>

Then, when I build and run the project using mvn clean install tomcat7:run, I get the following errors in my console, which fails the build:

Does anyone have any idea about what might be the problem? Note that I have tried this with both an empty web.xml file (besides setting a <listener-class> to a child of GuiceResteasyBootstrapServletContextListener in order to customize Guice in RESTEasy) and a web.xml file that uses servlet configuration for standalone servlet containers for Servlet version pre 3.0 (link). Thanks in advance.

NOTE: If I were to instead start-up my application with the Maven Jerry plugin, via mvn clean install org.mortbay.jetty:jetty-maven-plugin::run, then my project will indeed build successfully.

È stato utile?

Soluzione

SOLVED!

One issue was that I should've been using mvn clean tomcat7:run-war instead of mvn clean tomcat7:run. As well, in contrast to what was said in the RESTEasy documentation, I needed to add a <servlet> tag for org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher in web.xml, despite the fact I was using a Servlet 3.0+ container.

Altri suggerimenti

Use

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>
