I have been trying to deploy a project that I created within eclipse but when I right click on the tomcat server and click "Add and Remove...", I got the message "There are no resources that can be added or removed from the server".
From what I understand it has something to do with the facets? I am not really sure to understand what is going wrong here.
Here is what I did for know:
I created a Maven project.
executed mvn eclipse:eclipse through the command line on the folder of the project
installed m2e
tried to add the project to the tomcat server
You probably want to use either mvn eclipse:eclipse OR m2e, but not both. m2e has gotten MUCH better in the last couple years, so that's what I would suggest.
Make sure you are using Eclipse for Java EE, otherwise you will need to install other plugins like WTP
Install m2e.
Install maven integration for wtp (from the eclipse marketplace)
make sure the artifact type for your project is war
Import Existing Maven Project in eclipse and browse to your pom to import the project.
It should give the correct facets to your project so it looks like a web project.

I am new to Maven and if you feel i am asking really basic question then please forgive me.
I am facing couple of problems with Maven mentioned below.
I am using Eclipse Luna 4.4.1 (Which comes with the Maven Plugin).Now i installed two plugins..out of which one is for subclipse(with SVNKit) and m2e-Subclipse which is used for integrating the maven with SVN.I downloaded the project in eclipse using svn plugin as "checkout as Maven project" and i could see the project being downloaded and now to remove all the errors related with the POM.XML i downloaded the Maven and given the local path of the Maven in the preferences > Maven > installations and changed the Global Settings and user settings files which are project specific.
1). Now even after doing all this circus i still can not see the Maven build options in my Eclipse.
2). I am not even able to clean the project from command prompt.
when i go to my project directory and type "mvn -version" which shows me the correct version of maven.
But when i try to clean it using mvn clean. it does not work.
Please help.
Regards.
I want to setup my work project in Eclipse, with following features:
1) Connect to SVN repository
2) It is a maven - multi module project
3) It is a spring project
If I import this project as Maven project I am not able to connect it to SVN repository.
If I check - out SVN repository, I am not able to set it up as Maven/Spring project.
And ideally I want to make it hot deployable, (as eclipse dynamic web project), so Development can be efficient.
How can I possibly do this.
I have setup eclipse Juno SR1 with Maven, STS, and SVN plugins.
What you can do is follow the below steps :-
Checkout from svn to your local drive.
As it is a mave nbuild project you will have the pom.xml file in the root of the project. Do a mvn eclipse:eclipse -Dwtpversion=2.0 on the project.
3.Open eclipse and go to File-->Import--> Existing projects into workspace.
This should do.
FYR see this
After the project is checked out into the Eclipse workspace, just remove the project by using the following action: -
right click at the project ---> delete ---> click ok
Please take a note, do not check the check box named "Delete project content on disk". We have just want to remove and re-import again.
All we need to do is re-importing by using the following action: -
File ---> Import ---> Maven ---> Existing Maven projects
This will help us to integrate the Maven with the SVN in Eclipse. We will see the revision information after the project name, folders, packages, classes, etc.
Anyhow to use Maven in the Eclipse, you should install the Maven Integration (m2e). Furthermore there is a useful plug-in to integrate the Eclipse WTP with the Maven as well. It is named Maven Integration for WTP.
I hope this may help.
I upgraded to Eclipse Juno(for Java EE developers). I installed Maven Integration for Eclipse through marketplace.
Just to test, I created a web app using maven-archetype-webapp. I cannot run on server(There's no menu Run On Server). The same happens with another maven project which runs fine using Eclipse Indigo. A tried deleting .settings, .classpath, .project then re-importing the project but nothing. I was hoping so much on Juno!
Does anyone know a real solution to this problem?
May be Dynamic Web Module in Project Facet is not selected
Go to :- Project > Properties > Project Facets > check Dynamic Web Module
How about installing the m2e-wtp plugin and trying? You would want to confirm that the maven project is of war packaging as well.
Run on server is not a maven feature, it's a "classic eclipse" feature.
In order to run a maven project on a server you must adopt a plug-in (e.g a Jetty plug-in for your webapp) and the run the proper maven goal (e.g jetty-run).
Said this, you can run a web project on a server with (right-click) > Run as > Run on server if you have the proper runtime environment configured.
Enabling "Dynamic Web Module" in Project Facets may not help here in maven projects.
Because maven projects are structured differently (target/sampleApp-1.0-SNAPSHOT.war) than the normal Dynamic Web Projects (WebContent/).
So, If you use Dynamic Web Module manually, then eclipse will try to use "WebContent" directory structure as deployment directory for Application Server which won't be the case in maven projects.
Solution is to use m2e-wtp plugin to do the deployment.
If you installed m2e-wtp plugin, it'll automatically detect your maven project type & it'll show you the "Run as Server" option in "Run as" menu in "Project".
I'm running through the jboss as7 getting started guide here http://hudson.jboss.org/jenkins/job/JBoss-AS7-Docs/lastSuccessfulBuild/artifact/guides/developer-getting-started-guide/target/docbook/publish/en-US/html/helloworld.html . The tutorial has us setting up an example helloworld quickstart maven project.
I'm able to deploy this project from the command line successfully
mvn package jboss-as:deploy
but when I attempt to deploy the helloworld example from Eclipse - the 'run on server' option is missing from the run menu. I have Eclipse 3.7 and maven wtp installed.
Not sure how to fix, any advice appreciated.
The run on server related options only appears if your project has the Dynamic Web Moudle project facets.
You can try to configure it using the Project Facets options in your project properties
To help any other developer with this problem.
I was dealing with this issue recently. Maven projects are structured differently than Dynamic Web Projects. So when you manually add the Dynamic Web Module using Project Facets, eclipse may not register it properly as a Maven project.
To solve this, you have to install the m2e plugin and M2E Eclipse WTP plugin (this tells Eclipse how to run your maven projects).
Go to Help -> Eclipse Marketplace to search for the plugins.
After installing, you will need to restart Eclipse then you will be able to use "run on server" for your Maven projects.
Note: You may need to remove/delete the previous project then import/create it again after the restart.
You have to add maven eclipse pluginin your pom.xml file..
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.9</version>
</plugin>
According to Red Hat's site, The M2E Eclipse WTP plugin (m2eclipse-wtp) has been deprecated in favor of the newer m2e-wtp plugin. If you don't want to go through the marketplace, the URL for the new plugin is http://download.eclipse.org/technology/m2e/releases.
After copying the project and refreshing it, closing and reopening it, removing and re-adding it (right-click on server) and updating Maven... the option reappeared.
I think it occurs when you up the version of the Java compiler in your .pom file, when you up the compiler in project properties or it has to do with using the newer Jersey (2) version or when you both include local libraries and maven dependencies, it may also be a consequence of a combination of these. It's pretty unclear.
Note though, that you can still add/remove projects by right-clicking on the server in the servers tab.
I successfully created a project using Wicket quickstart and turned it into an Eclipse dynamic web project by running
mvn eclipse:clean eclipse:eclipse -Dwtpversion=2.0
I imported the project to Eclipse without any issues, but got this warning for each JAR:
Classpath entry M2_REPO/**.jar will not be exported or published.
Runtime ClassNotFoundExceptions may result.
I can fix this by using right click → QuickFix on each warning and selecting "Mark the associated raw classpath entry as a publish/export dependency," but this takes a lot of time and would not be possible if there were a lot of dependencies.
There must be a way to have Maven do this for me; what is it?
EDIT: I've found out that using m2eclipse core + Maven Integration for WTP (from m2eclipse extras) resolves my issues.
I'm still interested in how to achieve this without m2eclipse, though, just out of curiosity :p
The two Maven plugins needed to work with web projects in Eclipse are available from the Eclipse Marketplace.
Maven Integration for Eclipse (included in the Java version of Eclipse)
Maven Integration for Eclipse WTP
