  • have you added Mvp4gModule's jar in your java build path? – RAS May 28 '12 at 10:13
  • no,it added by dependency in ivy.xml. – Kiran Bhalerao May 29 '12 at 06:30
  • I don't know much about Ivy but yesterday only I got the same exception. I'm using Java. So the problem was that it was expecting the jar in build path as well as at physical location (in lib folder where it goes to find all jars). & my problem got solved. Hope this information helps you. – RAS May 29 '12 at 07:24
  • I also tried same way my application compile properly but when i try to run it on console following two lines are coming and the url for app not generating.ERROR [Reflections] - given scan urls are empty. set urls in the configuration [WARN] No startup URLs supplied and no plausible ones found -- use -startupUrl – Kiran Bhalerao May 29 '12 at 10:30

Analysis

After digging around the project homepage, I've discovered that the missing XML file is actually located inside the jar file:

unzip -t ./Mvp4g_Layout_Part2/war/WEB-INF/lib/mvp4g-1.4.0.jar | grep xml
testing: com/mvp4g/Mvp4gModule.gwt.xml   OK
testing: META-INF/maven/com.googlecode.mvp4g/mvp4g/pom.xml   OK

This means while the may have been downloaded by ivy, it is not present on your compile classpath.

Assumption

You haven't specified how you're using the jar, so I must assuming the above error was thrown by the ANT javac task.

Example

ivy.xml

I'd declare the dependency in ivy and associate it with a compile configuration as follows:

<ivy-module version="2.0">
    <info organisation="com.myspotontheweb" module="demo"/>

    <configurations>
        <conf name="compile" description="Required to compile application"/>
    </configurations>

    <dependencies>
        <dependency org="com.googlecode.mvp4g" name="mvp4g" rev="1.4.0" conf="compile->default"/>
    </dependencies>

</ivy-module>

build.xml

In the ANT file I'd use the ivy cachepath task to create an ivy managed ANT path.

<target name="init">
    <ivy:resolve/>

    <ivy:report todir='${ivy.reports.dir}' graph='false' xml='false'/>

    <ivy:cachepath pathid="compile.path" conf="compile"/>
</target>

This path is then used as normal in the javac task (or any other ANT task that can accept a classpath reference)

<target name="compile" depends="init">
    <javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false" debug="true" classpathref="compile.path"/>
</target>
