Maven Eclipse Integration - eclipse

I have recently started out on Maven. I am trying to integrate Maven+eclipse(Juno)+tomcat7.
I have downloaded m2e-wtp plugin for eclipse and created a Maven project whose structure follows a standard Maven project structure. It is also configured a dynamic web project.
It is a multi module project with two modules of flex(f1 AND f2) and one module of webapp(w).I have configured all the plugins correctly and there is no problem with configuration of POMs.
What I want to achieve is :
When I clean and Build project in Eclipse using Project-->Clean,Eclipse does not build the war in target folder of my web application project (w). I also does not copy any of the flex resources to target folder. However,
When I run the project as maven build by right-clicking the web application project and running it as a "maven install" it creates everything as expected.
My question is that if it is possible to achieve what I mentioned in point (1)? Or the only correct way to do this is the way mentioned in point (2).
I am also not able to deploy the generted files in step 2 automatically in tomcat.
Do I need to use another maven plugin for this?
Please note that this i my first experience with Maven + eclispe. I have followed certain tutorials. So, Please be lenient while voting negatively.

From what I know it is not possible to force Eclipse to use Maven directly (I would gladly be proven wrong).
Eclipse does not use Maven to build (1). Using the m2e plugin, it is possible to run maven to perform the build as you discovered (2).
If you are looking for that kind of tight integration you can look at NetBeans or IntelliJ who are using Maven natively.
EDIT:
About (3) there is a Tomcat-Maven-Plugin that can deploy the WAR file created on a running tomcat instance. Check the Usage page for more details.

Eclipse-Kepler, Maven and Setup Tomcat 7 debug (hot deploy)

I have maven based project with following structure:
main_project
module_webproject
module_java_proj_1
module_java_proj_2
module_java_proj_3
... ...
Everything compiles and packages fine with command line maven goals execution. I need to setup this project into eclipse environment for developers with tomcat deployment. Anyone know setup instructions?
Also, i am looking into tomcat hot deploy for debugging capabilities.
I have tried mvn eclipse:eclipse, this does only creation of .project and .classpath files. But projects directories are not treated as java or web projects.
Answer from following forum some what helps...
[Running Maven project on Tomcat from Eclipse
There can be a few reasons why you don't see the project in the Add/Remove projects dialog for Tomcat. Verify the following:
You have m2e installed (http://eclipse.org/m2e/download/)
You have m2e-wtp installed (http://www.eclipse.org/m2e-wtp/download/)
Your Maven project imported as a Dynamic Web Application. Look for a Deployment Descriptor entry when you expand the project, it should be somewhere in the first few entries. It is the second one down for me on Eclipse Juno. Not there? It's probably not a web app. Go back and verify 1 & 2, then remove and re-import your project.
Make sure that your web application is not too new for the version of Tomcat that you are using. Right-click the project and go to Properties > Project Facets. Look for Dynamic Web Module and check the version. If this version is too new for your Tomcat version, Eclipse won't let you add it. For instance, your Dynamic Web Module version is 3.0 and you're using Tomcat 6.

Use Maven for dependencies together with GWT Plugin?

So far I'm not using maven for a GWT project. When I deploy it to the GAE Google App Engine, I just have to right click > Google > Deploy to App Engine. Then the war folder is generated automatically and everything runs fine.
If I change the project to maven structure, the menu point in project settings > Google > Web Application tells me: Launch and deploy from this directory (disabled because Maven).
As a result, when deploying, the war folder is not generated/updated!
So: how can I use maven for dependency management, and still use the GWT/GAE Eclipse Plugin to deploy and start my app?
You might want to go through this introductory exercise in maven : http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html
What you are describing is possible, but takes some work and understanding of maven to accomplish. If you would like to convert your project to maven, it might take a bit more work than just changing the project to the maven structure in eclipse. An example maven project for App Engine is here : https://github.com/GoogleCloudPlatform/appengine-guestbook-java . Some App Engine specific docs on maven are here : https://developers.google.com/appengine/docs/java/tools/maven

Implementing simple modules or extensions for axis2 as an eclipse project

I wish to setup an eclipse project for implementing a simple module but not a service for axis. I wonder if there're any templates I could use?
Secondly, I would like to ask if there are any information sources such as links around on how to build complex Axis2 applications in eclipse mainly focusing on module building as well
I appreciate your hints.
Best regards,
Alex
I could come along with this issue with my own solution:
Using an customized build.xml based on axis2 module builds I am able to build a module project in Eclipse using ant. I trigger this via key shortcut.
The build.xml has an deploy.module target that puts the module back to the axis2 $HOME/repository folder. Running there ant build.xml will deploy axis2 at whole as an war-file (EAR) the module containing there within to be ready to deploy in a container such as jboss.
The eclipse project is based on common java project (no dynamic web project) containing the $AXIS2/lib in CLASSPATH.
Since Jboss supports hot deployment on update, you can run jboss in a terminal or withing eclipse. I customized the latter build.xml to support easy jboss deployment.
This is a good solution for me.

Integrate War-Plugin for m2eclipse into Eclipse Project

I set up a small web project with JSF and Maven. Now I want to deploy on a Tomcat server. Is there a possibility to automate that like a button in Eclipse that automatically deploys the project to Tomcat?
I read about a the Maven War Plugin but I couldn't find a tutorial how to integrate that into my process (eclipse/m2eclipse).
Can you link me to help or try to explain it. Thanks.
I set up a small web project with JSF and maven. Now I want to deploy on a Tomcat Server.
During development I recommend to use Eclipse Web Tools Platform (WTP). M2Eclipse provides support for it (assuming you have Maven Integration for WTP installed) and your project should be recognized as a Dynamic Web Project runnable on a Server.
So, declare Tomcat as a Server (show the Servers view and right-click in it to add a Server via New > Server). And deploy your project to it (right-click on your project then Run > Run on Server).
There are other options like using the Tomcat Maven Plugin or the generic Cargo Maven Plugin but I wouldn't use them for development and, since you are a Maven beginner, I don't recommend them at all. Use your IDE.
I read about a the Maven War Plugin but I couldn't find a tutorial how to integrate that into my process.
Actually, the Maven War Plugin is only responsible of the packaging of your webapp project (it is bound automatically on the package phase when using a <packaging>war<packaging> for your project). It isn't used for deployment. But as I said, use your IDE to deploy your application during development.
The war plugin is for generating war files, not for deploying them. What you are asking for may be provided by the Cargo Plugin. Another interesting candidate for you could be the jetty-maven-plugin.

Can't get compile on save / hot deploy feature to work with maven based webapp in eclipse or netbeans

So our new webapp project is based on maven. I'm really liking the dependency management and IDE agnostic approach but I'm having problems with compilation and debugging.
Here's how I would currently get a clean copy of the project working
Check out the main project from SVN
Open the project in IDE (I've tried in eclipse 3.4 and netbeans 6.7)
The IDE will automatically open two subprojects one being the webapp, the other being a supporting utils jar.
From the command line I run mvn war:inplace on the webapp module which builds a working copy of the webapp with all dependencies in WEB-INF/lib/
This then runs fine but whenever I change a java class I have to clean and build / reload the app context.
I've googled high and low but no one seems to be complaining about this so I guess there must be something really obvious I'm missing. How is everyone else handling incremental compilation and hot deploy with maven?
To clarify all I'm looking for is the replicate the behavior I used to have before maven where I could make simple changes to java classes and they would be instantaneously compiled and hot deployed to a running webapp. I don't need anything fancy like jRebel etc I just want the new tool to give me the same functionality I enjoyed with my old tools.
If you can use mvn jetty:run it will read the classes and resources directly from the project. Using Maven2 Eclipse plugin and running the server embedded in Eclipse has auto-publishing, which gets you there in the end, although it's slower. And JRebel starting with 2.0 (as you may know) can map the Maven module directly to the deployed application, so you get instant build and redeploy. Those are the only solutions I know of.
Netbeans should support it out of the box. Though, there remains a bug related to this: http://netbeans.org/bugzilla/show_bug.cgi?id=177230
In-place deployment works for me with Netbeans 7.0.1 and Tomcat 6.0.x if I use Tomcat 7.0.x in-place deployment doesn't work. Tomcat always copies application to $CATALINA_HOME/temp :(
