I started to use Maven in Eclipse (m2eclipse) recently. Unfortunately lately I've been unable to run the application from Eclipse. I get the error:
Loading modules src.main.java.com.ohapp.webconfuturo.WebConfuturo
Loading inherited module 'src.main.java.com.ohapp.webconfuturo.WebConfuturo'
[ERROR] Unable to find 'src/main/java/com/ohapp/webconfuturo/WebConfuturo.gwt.xml' on your
classpath; could be a typo, or maybe you forgot to include a classpath
entry for source? [ERROR] shell failed in doStartup method
I already checked and the file is there. Isn't visible in Eclipse but is in the file system.
Strangely if I run the program through Maven (mvn gwt:run) it works just fine.
My pom.xml (without the dependencies) is the following:

What am I doing wrong?
Thanks
I figured this one out. The arguments in my Run settings where wrong. I had the the gwt.xml file referenced with full path and not relative to source folder:
src.main.java.com.ohapp.appname.AppName
I changed it to:
com.ohapp.appname.AppName
And problem solved.
I don't know how this happened since it wasn't me who made the changes.

I'm trying configure my Eclipse (Kepler), when I execute Run as -> Maven Clean, that works. After I execute Run as -> Maven Install, this error below is showed in console.
There's a solution? Thanks for attention.

I have a strange problem with maven. I am using the filtering option to put some version information into a properties file. I then include that in the jar file, so that "Help/About" can tell me something useful. The problem I am having is that the version in the jar file is the previous version. So, if, for example I run a build at 0930, and another at 0940, then the version of the properties file in the jar generated at 0940 will have a build time of 0930. I am using the buildNumber plugin as well, but this issue is present whether or not I enable it.
What is even stranger is that when I run my build from within eclipse and run the program, the "old" file shows up on help/about, but then when I "Refresh" (F5) the eclipse project and re-run the program, I get the correct version. So could it be that maven is taking the eclipse version somehow? And why do you need to "refresh" in eclipse to get it to have the most up to date version.
Anyway, my pom.xml is

The first thing is to activate the filtering of your resources like this:
<build>
<resources>
<resource>
<directory>src/main/resources/</directory>
<filtering>true</filtering>
</resource>
</resources>
...
</build>
This will activate the filtering for all files which are in the folder (and subfolders) of src/main/resources. Sometimes you need the filtering only for a limited number of files. In such sutuations just put those files into a subfolder and change the above configuration appropriately.
Next is to define a property file (in src/main/resources folder) which contains all information you need like this:
version=${project.version}
buildNumber=${buildNumber}
buildTime=${maven.build.timestamp}
Furthermore do the configuration for the buildnumber-maven-plugin like this:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>false</doCheck>
<doUpdate>false</doUpdate>
<revisionOnScmFailure>UNKNOWN</revisionOnScmFailure>
<format>{0,date,yyyy-MM-dd_HH-mm}_{1}</format>
<items>
<item>timestamp</item>
<item>${user.name}</item>
</items>
</configuration>
</plugin>
After that you can simple remove the usuage of the maven-replacer-plugin which you don't need in such simple scenarios.
I've ran the mvn
mvn archetype:generate \
-DarchetypeGroupId=org.codehaus.mojo \
-DarchetypeArtifactId=gwt-maven-plugin \
-DarchetypeVersion=2.5.1
As described: http://mojo.codehaus.org/gwt-maven-plugin/user-guide/archetype.html
Then in Eclipse I import the project via "Import Maven Projects"
I get the following error:
gwt-maven-plugin:2.5.1:i18n (1 errors)
No marketplace entries found to handle /pom.xml in Eclipse. Please see Help for more information.
Any suggestions?

Add the following to your pom.xml

<plugins>
<!--This plugin's configuration is used to store Eclipse m2e settings
only. It has no influence on the Maven build itself. -->
<plugin>
<groupId>org.eclipse.m2e</groupId>

It will tell eclipse to ignore this error.
I have created gwt maven project and I want run it so from command line I am providing:
mvn compile gwt:run -DrunTarget=com.engile.Engile/Engile.html
But In logs it shows:

In build path in source section I am providing outputfolder of src/main/java is target/classes and default output folder is:
engilev2_with_mavenold/src/main/webapp/WEB-INF/classes
is anything is wrong, I don't understand the webapp/classes folder and target/classes folder where java classes are compiled to ?
You have not configured gwt-maven-plugin in your build tag. You are only configuring maven-compiler-plugin and lifecycle-mapping plugin. The gwt-maven-plugin under lifecycle-plugin is only to inform eclipse to avoid invoking gwt compilation in refresh cycles,
You have the same issue in the other stackoverflow question too -
The parameters 'runTarget' for goal org.codehaus.mojo:gwt-maven-plugin:2.5.0:run are missing or invalid
Add another plugin tag in your pom.xml under buil tag after maven-compiler-plugin
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>gwt-maven-plugin</artifactId>
<!-- <versionRange>[2.5.0,)</versionRange> -->
<version>${gwtVersion}</version>
<goals>
<goal>resources</goal>
<goal>compile</goal>
<goal>i18n</goal>
<goal>generateAsync</goal>
</goals>
<configuration>
<runTarget>Engile.html</runTarget>
<hostedWebapp>${project.build.directory}/${project.build.finalName} </hostedWebapp>
<modules>
<module>com.engile.Engile</module>
</modules>
<!-- <runTarget>com.engile.Engile/Engile.html</runTarget> -->
</configuration>
</plugin>
After some tries, I don't get to make the hosted mode to work with maven. My pom.xml is the following and I'm using a standard maven structure:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>gwt-maven-plugin</artifactId>
<version>2.4.0</version>
<executions>
<execution>
<goals>

<configuration>

</configuration>

Any ideas?
Here is the POM I used in a presentation today that works if you want to compare them: https://github.com/checketts/gwt-spring-demo/blob/master/pom.xml.
I noticed two missing tags <outputDirectory> under build and <module> under gwt-maven-plugin configurations.
Also reference - http://code.google.com/p/google-web-toolkit/source/browse/trunk/samples/dynatablerf/pom.xml
<build>

Try adding these configuration entries :
<warSourceDirectory>${basedir}/src/main/webapp</warSourceDirectory>
<webappDirectory>${project.build.directory}/${project.build.finalName}</webappDirectory>
<hostedWebapp>${basedir}/src/main/webapp</hostedWebapp>
The last one may be the real needed one actually
