Re: [jbehave-user] use of maven embedder and scope=provided dependencies

[Mauro Talevi]

Hi Brian,

the JBehave mojos use the @requiresDependencyResolution <scope> to 
resolve dependencies, where the default scope is "runtime", which does 
not include "provided" dependencies.

In general, this tends to work as JBehave stories are run either at 
compile scope - in their own Maven project - or in test scope.

May I ask you why you feel the need to declare your dependency as 
provided in a testing module?

I've tried out your project and it works fine if you declare your 
dependencies at "compile" scope.   I'm using latest Maven release 3.0.4 
and latest JDK 1.6.

Else, explicitly declaring the dependency in the plugin <dependencies> 
also works.

Cheers, M

Hi,

I've created a dumb project on github using a jbehave artifact: 
https://github.com/bclozel/jbehave-scope-provided
Maven documentation 
<http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope> 
says scope=provided dependencies are within compile + test classpaths. 
JBehave embedder is using both depending on configuration.

    mvn --version
    Apache Maven 3.0.3 (r1075438; 2011-02-28 18:31:09+0100)


With this configuration, my embedder classpath does not contain the 
javax.servlet JAR. When the dependency scope is changed to "compile", 
then this JAR is listed in classpath elements.

Any pointer here would be really helpful.

Thanks,

    Hi Brian,

    can you provide us with a sample project (with pom.xml and the
    simplest source possible) reproducing this issue?

    Thanks

    Hello there

    I've been trying to use jbehave on a project and I ran into some
    problems.
    When running the maven goal, I got the following error:

        [ERROR] Failed to execute goal
        org.jbehave:jbehave-maven-plugin:3.6.7:run-stories-as-embeddables
        (default-cli) on project springmvc-router: Execution
        default-cli of goal
        org.jbehave:jbehave-maven-plugin:3.6.7:run-stories-as-embeddables

        org.jbehave:jbehave-maven-plugin:3.6.7:run-stories-as-embeddables:
        javax/servlet/http/HttpServletRequest


    It looks like jbehave's Embedder classloader can't locate
    the HttpServletRequest. This dependency is declared in my main
    POM like this:

              <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
                    <version>2.5</version>
                    <scope>provided</scope>
                </dependency>


    If I ever change the scope to "compile", I get another error saying:

        Caused by: java.lang.InstantiationException:
        org.myproject.OneOfMyProjectClasses
        at java.lang.Class.newInstance0(Class.java:340)

org.jbehave.core.embedder.EmbedderClassLoader.newInstance(EmbedderClassLoader.java:37)
        ... 24 more



    Is there a typo/bug in my configuration?
    I've browsed jbehave-maven-plugin (AbstractEmbedderMojo to be
    precise) but couldn't anything on dependencies in provided scope.
    Should I open an issue about that?

    This is the maven config I've added to my POM:


                    <plugin>
        <groupId>org.jbehave</groupId>
        <artifactId>jbehave-maven-plugin</artifactId>
