Unknown argument: -XfragmentCount

[pierre.q...@gmail.com]

Hi,

I'm trying to compile GWT with Eclipse and Maven and I'm nearly desesperate to see that after two struggling days, it doesn't work for the moment.
Please let me know if you have any idea on how to resolve this issue.

Thanks !


This is a sample of my pom.xml :

            <!-- GWT Maven Plugin -->
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>gwt-maven-plugin</artifactId>
                <version>2.5.1</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>compile</goal>
                            <goal>test</goal>
                            <goal>generateAsync</goal>
                        </goals>
                    </execution>
                </executions>
                <!-- Plugin configuration. There are many available options, see gwt-maven-plugin
                    documentation at codehaus.org -->
                <configuration>
                    <runTarget>TMobile.html</runTarget>
                    <hostedWebapp>${webappDirectory}</hostedWebapp>
                </configuration>
            </plugin>

And here a sample of the output log :

The problem is that you're using the gwt-maven-plugin 2.5.1 with GWT 2.0.3. gwt-maven-plugin 2.5.1 is only supposed to work with GWT 2.5.1.

That said, passing "-XfragmentCount -1" as argument whereas you didn't specify anything in your pom.xml is probably a bug too, but it doesn't seem to be an issue with GWT 2.5.1.

[pierre.q...@gmail.com]

Hi,

I don't understand why GWT 2.0.3 is used.

Above, in my pom.xml, GWT is defined as :

    <properties>
        <!-- Convenience property to set the GWT version -->
        <gwtVersion>2.5.1</gwtVersion>
        <!-- GWT needs at least java 1.5 -->
        <webappDirectory>${project.build.directory}/${project.build.finalName}</webappDirectory>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <dependency>
            <groupId>com.google.gwt</groupId>
            <artifactId>gwt-servlet</artifactId>
            <version>${gwtVersion}</version>
            <scope>runtime</scope>
        </dependency>
        <dependency>
            <groupId>com.google.gwt</groupId>
            <artifactId>gwt-user</artifactId>
            <version>${gwtVersion}</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>com.googlecode.mgwt</groupId>
            <artifactId>mgwt</artifactId>
            <version>1.1.2</version>
        </dependency>

Any idea ?

Thanks !

[Thomas Broyer]

I'd blame mgwt (though honestly, the real culprits are Maven and GWT, in this order).

Either use an <exclusion>, or explicitly depend on gwt-dev:2.5.1 (with scope=provided) to override the transitive dependency on gwt-dev:2.0.3.

[pierre.q...@gmail.com]

Moreover, my GWT SDK is linked to 2.5.1

A grep in my directory shows :
grep -ri "2.0.3" .
Binary file ./Mobile/target/Mobile-0.0.1-SNAPSHOT/WEB-INF/lib/gwt-dev-2.0.3.jar concordant
Binary file ./Mobile/target/Mobile-0.0.1-SNAPSHOT/WEB-INF/lib/gwt-servlet-2.5.1.jar concordant
Binary file ./Mobile/target/Mobile-0.0.1-SNAPSHOT/WEB-INF/lib/gwt-servlet.jar concordant
Binary file ./Mobile/target/Mobile-0.0.1-SNAPSHOT/WEB-INF/lib/mgwt-1.1.2.jar concordant

But I do not know where gwt-dev-2.0.3 is coming from !

[Thomas Broyer]

"mvn dependency:tree" will tell you, but I'd bet mgwt.

BTW, mgwt should probably have scope=provided.

…and there's no reason for that un-versionned gwt-servlet.jar. You're using M2Eclipse to import your project in Eclipse, aren't you?

I'm getting same error due to gwt-maps-api (https://github.com/branflake2267/GWT-Maps-V3-Api) dependency.

Solution is to have a dependency on gwt-dev in my own pom with a version I want.

<dependency>
 <groupId>com.google.gwt</groupId>
 <artifactId>gwt-dev</artifactId>
 <version>${gwt.version}</version>
 <scope>provided</scope>
 </dependency>

This however, results in a warning "[WARNING] Don't declare gwt-dev as a project dependency. This may introduce complex dependency conflicts".

Is there any better way to resolve this issue?

You could add an exclusion to your gwt-maps-api dependency, or (untested) set the gwt-dev version in your dependencyManagement.

[Joseph Lust]

A known problem fixed for future releases.

Nice job.

Exclusion solves the problem! Thanks everyone.

Perhaps we should update the Home page of gwt-maps-api lib (with interim solution) so that new users don't have to go through this painful route of Googling and asking on forums.
