So I was following http://www.mkyong.com/jsf2/jsf-2-0-hello-world-example/ for a simple tutorial on how to use maven and jsf. I created a maven project by running mvn archetype:generate -Dfilter=org.apache:maven-archetype-webapp in my command prompt. Then I continued with the tutorial, I wound up creating all necessary files, but then when I got to the end, I realized I did have a server created. So I created one real quick, but when it came to the point of adding files to the server (from the add or remove dialog box), no projects or files showed up. I am not on my computer where the project is located so I can't copy/paste the .pom file in, but it looks practically exactly like the pom in the tutorial (only difference is groupId, artifact, ect.) No additional plugins, dependencies, or configs.
Do you want to deploy the webapp within Eclipse to Tomcat? Or as some sort of automatic/continuous deployment?
Within Eclipse you often need to add the Dynamic Web project and JSF facets to your project so Eclipse recognizes the project as deployment capable. If you are using m2eclipse make sure to install the m2eclipse wtp add on so this is done automatically.
If you want to add auto-deployment to the pom.xml I recommend using the maven cargo plugin: http://cargo.codehaus.org/Maven2+plugin - it supports the major containers.
For tomcat you need to modify the tomcat-users.xml to allow auto-deployment and leave the tomcat-manager application in place. If you have startet tomcat and pointing your browser to http://localhost:8080/manager/html/list it should either tell you to login or what to add to that file.
The configured user is then used in the configuration to deploy the war file via the tomcat-manager using the mvn cargo:deploy goal. The configuration has to be added to the pom.xml using war as packaging, not to the parent-pom.xml

I hardly use Maven.The only time for me to use it is for maintaining my web app dependencies.
Now I started to develop web app using Spring Boot. I notice when I run Maven install, a WAR file will be created in the target folder. Then I export WAR using File > Export on my STS IDE and compare the two wars. The size of the 2 files are different. How can this be ? Also, the WAR file created from Maven runs fine on standalone Tomcat 7 while the exported war from Eclipse (STS) doesn't.
What am I missing here ?
It's reasonable to assume that WTP (File > Export > Web etc) would produce a different WAR file from the maven build. Maven build may have plugins applied to the build to produce the desired WAR file. Check your POM file carefully and check if there are any maven plugins used in the build.
Now, I don't exactly know how Eclipse WTP component produces their WAR file (Export WAR file is not from STS - it's Eclipse WebToolsProject) from the project. There might be options in the export wizard to play around with or some configuration file in your project. You'd better off asking that on the Eclipse forum: https://eclipse.org/forums/index.php?t=thread&frm_id=88
Hope this helps.
Forgive me asking following questions. I am totally lost in regards to maven+eclipse. I checked out someone's java project (maven built) from SVN to my local eclipse (kepler). When I click Windows > Preferences, I see Maven.
question 1)
Is this a maven plugin? When developers say maven in eclipse, are they referring to maven plugin? maven and maven plugin are two separate components?
question 2)
when I click on user settings, C:\Users\myName.m2\settings.xml is missing. Exact error message is "User settings file doesn't exist". Does it get created when you install maven plugin at first time?
question 3)
I found three folders may have to do with maven C:\workspace\maven_local_repo_artifactory directory, C:\maven_local_repo and C:\Users\myName.m2\respository but not sure how they get created and what is the relationship among them.
question 4)
Is it ok to remove current maven plugin from eclipse and re-install it then check out the java project from SVN? I think my maven or maven plugin settings are not correct in my local box.
1) Is this a maven plugin? When developers say maven in eclipse, are
they referring to maven plugin? maven and maven plugin are two
separate components?
Yes. This is the maven-plugin. maven-plugin uses the configurations of maven (%M2_HOME%/conf).
If you wanna work with maven, you need to install it on your machine. Then you can run maven commmands. In addition, if you want to invoke maven commands within eclipse (conveniently) - you can install the eclipse-plugin. "maven-plugin" is a plugin for eclipse, that lets you use maven within Eclipse conveniently.
2) when I click on user settings, C:\Users\myName.m2\settings.xml is
missing. Exact error message is "User settings file doesn't exist".
Does it get created when you install maven plugin at first time?
By default, the maven-plugin assumes that your settings.xml (which is the configuration file of maven) is in the path you have mentioned. However, there are cases (like in my case) where the config file is not there, but under %M2_HOME%/conf. you can update it in Eclipse, and the error will disappear.
3) I found three folders may have to do with maven
C:\workspace\maven_local_repo_artifactory directory,
C:\maven_local_repo and C:\Users\myName.m2\respository but not sure
how they get created and what is the relationship among them.
C:\Users\myName.m2\respository is the "local repository". If you learned a bit about how maven works, it holds a local repo on the local machine, and it keeps there all artifacts. It downloads them from the "repository" - if you have one in your company (Nexus, Artifactory, etc) or from Maven Central. However, this path is configurable by Maven's settings. So there might be that someone played with it and changed the path, and these other directories were created. You did not mention what resides inside these paths...
4) Is it ok to remove current maven plugin from eclipse and re-install
it then check out the java project from SVN? I think my maven or maven
plugin settings are not correct in my local box.
Sure it is OK. You may remove the plugin, and the source plus maven itself will not be deleted from your machine.
HTH.
I followed this tutorial http://www.mastertheboss.com/jboss-maven/jboss-maven-example-building-a-java-ee-6-application/ in order to have a simple web application to better understand Java EE and JBOSS. I set up the example project (by archetype) and compiled it.
However, I am stuck after running mvn compile. I want to deploy my application as a war file to my JBOSS webroot directory (in my case /usr/share/jboss-as/standalone/deployments/).
I think mvn package and mvn install must be executed. Where can I specify that I want a war file and that it should be copied to my deployment location on JBOSS?
Obviously, I can use the jboss maven plugin http://docs.jboss.org/jbossas/7/plugins/maven/latest/, which is addressed via console
jboss-as:deploy
Configuration is read from the POM file.
Hi I am trying to port a mid sized Maven project to IntelliJ Idea 12 (from Eclipse).
There are around 30 different modules in the project.
I am running an MVN install on each module via IntelliJ lifecycle management.
The jars are being correctly generated, and deposited into my local repository directory. It is also correctly picking up the third party libraries.
However IntelliJ is sometimes requiring me to then add the generated jars to my classpath as a dependency. (It is not enough to simply say "Add Maven Dependency", I have to physically add the generated jar as a library.)
In other cases it works correctly. Not sure why it is not consistent.
Have you tried updating the local Maven repository in IntelliJ IDEA? You can do so by opening Preferences->Maven->Repositories, than select your local repository and click on 'Update'.
I have maven war project.
I know inplace. it deploys to a given server. But i want to deploy on embedded tomcat and dont want to restart everytime. just say
for first time run deploy
Then change some java class and say redeploy. All in embedded tomcat.
Is this possible ?
Could the Tomcat Maven Plugin help with this?
You can use it by using the command tomcat:run
This page describes how to set up your POM/settings to make calling the plugin easier (using a prefix vs having to use full groupId/artifactId of plugin on the command line).
Maybe you can have a look at the executable war/jar feature see http://tomcat.apache.org/maven-plugin-2/executable-war-jar.html
So that will produce a simple jar which contains tomcat classes. You will be able to simply run: java -jar pathtofile.jar.
