I am currently migrating our build process from Eclipse/Ant to Maven/M2Eclipse/Artifactory. I have a Webapp as a WTP project in Eclipse. I have migrated it to Maven with m2eclipse.

The compilation runs fine from the Eclipse IDE.

However, when I try to compile from Maven CLI (mvn clean & mvn compile), Maven complains about not finding the libraries provided by the Tomcat Environment (like annotations-api, servlet-api, etc, ...).

Fair enough : Indeed, these dependencies are provided by WTP, as Java resources / Libraries / ApacheTomcat6. Maven is not aware of them.

I could deactivate this in the build path, and add each corresponding dependency in my POM, but I'm afraid this would lead Maven to deploy them again in my webapp (WEB-INF/libs).

So, what is the good way to say to maven "this application will run in a well known environment, providing the following libraries ". Is there some common Tomcat POM that I could add as a dependency ?

Thanks in advance for your advice. regards,

Raphael

One way to handle this is to declare these dependencies with scope provided. These dependencies will be available for compile and test, but will not be packaged by maven into the webapp. For example,

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.0</version>
            <scope>provided</scope>
        </dependency>

    Above is the way you need to define in your pom. change the scope to provided so maven does not include those jars in your final build.

    Thanks,Do you know if Tomcat provides a POM project with all libraries already listed as "provided" ? I could then add it as a dependency.

  • @RaphaelJolivet that would be neat, also looking for this (but for Glassfish, actually). Did you find anything?

  • Is it possible to have m2eclipse (or mvn eclipse:eclispe) add the dependencies to the generated project/classpath ?
