These are the steps I followed:
Created a maven project in eclipse.
Converted the project into faceted form.
Added the project to the server.
Now whenever I make any changes to my project resources, it gets reflected in server. But my WEB-INF/lib directory doesn't contain any maven dependency jar files.
How to fix this?
If you use Eclipse WTP, Maven dependencies are provided by WTP to the application server using some kind of special classpath container (as you see it in your project in Eclipse). So they are not copied to WEB-INF/lib directory but rather somehow "injected" by the WTP extension. But if you build Maven artifact (mvn package) everything should be OK.
I installed m2e integration for WTP and now it is copying the maven dependecies jars into WEB-INF/lib of the server installed apps directory.

I'm starting to use Maven (M2E) on Eclipse.
I have two projects
->Tools
->Main
The Main project requires the Tools project. I add "Tools" under the "Main"->"Deployment assembly" option, and when exporting to WAR, the WAR will automatically contain also Tools.jar. This is correct.
Now I installed M2E on the Main Project, to manage some spring dependencies. When I edit the pom.xml, Maven starts, and correctly downloads the Spring jars, but it removes the Tools project from the "Deployment assembly" option (it disappear from the org.eclipse.wst.common.component eclipse configuration file)
As a result, when I export the WAR from Eclipse->Export, the war will not contain Tools.jar, so the webapp will not work.
How do I configure pom.xml to do what Eclipse does with the "deployment assembly"?
That is, package all classes and resources and jar dependencies of the Tools project?
I think that I'm missing some understanding of Maven, but I've not been able to google about it?
thank you
I'm using the Eclipse "Internal Glassfish 3.1.2.2" server with the Eclipse Glassfish plugin (http://download.java.net/glassfish/eclipse/juno). I'm also using Maven with the m2e Eclipse plugin. The Glassfish plugin correctly deploys my EAR modules to the Internal Glassfish, but it does not deploy my dependency jars, which I believe should end up in a folder called "lib".
I found a partial solution here, which is to add my maven target lib folder to the EAR Deployment Assembly (double-click in the Deploy Path box to edit). This works, but m2e (or m2e-wtp) undoes the config change when I do Maven > Update Project.
There ought to be a cleaner solution. The Eclipse Ear Module Assembly dialog has a field to name the "EAR library directory", so it's aware of the lib folder. Where does Eclipse EAR assembly (without Maven) look for jars to put in the lib folder? I assume the Glassfish plugin is looking in the same place.
You can use the following steps to find the source of the problem:
Take Eclipse out of the equation and build EAR on command line using Maven, does it turn out ok? If not, look for a solution in your pom.xml.
If ok so far, open Eclipse and perform Maven -> Update Project. Then export EAR using Eclipse (look for EAR export wizard under File -> Export). Did the exported EAR turn out ok? If not, file a bug report for m2e-wtp plugin. It is still pretty raw, so it wouldn't be surprising if it doesn't setup Eclipse metadata correctly in some cases.
If ok so far, then it is time to look for a problem in Glassfish plugin. I doubt that you will get this far, but if you do I will help you to follow up.
I have configured my POM to include the Maven-Surefire plugin, as well as a dependency to a repository with some Selenium stuff.
After running mvn eclipse:eclipse, my project now has 100 jars, including the Jetty, Spring, and Selenium jars, all at the root of the project.
The project builds and runs fine, but how can I put the jars into a directory so it doesn't look so bad? Is this something I can configure in the POM?
Instead of using the maven eclipse plugin ("mvn eclipse:eclipse"), you could use maven eclipse integration plugin (m2eclipse), all your jars will stay in the local repository.
We have existing maven project. I have imported it with m2eclipse plugin.But
I can not run the project. Tomcat can not see resources(WAR files under target folder).
What am I missing? BTW we have multi-module project(2 WAR files).
Thanks in advance!
You need to add the tomcat server in your eclipse.
The maven project should be a web based project
You need to add the web project to the tomcat server.
You need to add J2EE Module Dependencies - Eclipse 3.3 ( To enable all library dependencies to be available at runtime to tomcat). Paths that point to your m2 repo & the lib files.
It may be Java EE Dependencies in earlier versions.
Both your projects needed to be added similarly.
How can I import a maven EAR project into Eclipse 3.4, and be able to use the IDE (WTP) to deploy the ear successfully to Weblogic (9.2)?
The main issue is that the dependent jars are not being included in the ear (under APP-INF/lib) when it gets deployed through the IDE. When I build from command line, the ear is exactly how I want it.
I am using the APP-INF/lib configuration for the ear plugin, and have included the jarModule sections for all the required jars.
When editing the eclipse EAR project's Java EE components, all the jars are listed, but not in the APP-INF/lib. Only when I open a dependent jar project do those specific jars get set under that subfolder. All the 3rd party jars are showing they will end up in the wrong place.
If you need more info, just let me know. Thanks!
You might want to use maven to create the eclipse WTP projects for you. This might be helpful.
The Using maven-eclipse-plugin in multi-module projects with WTP of the maven website describes how to develop Multi-module projects with Maven and Eclipse efficiently using the best of both Maven 2 and Eclipse's WTP. This covers projects that have EJB and EAR modules.
An fully working example of a multi-module projects, containing some JAR-, a WAR- and an EAR-project is even available for download if necessary.
