I checked out a maven project and imported to my Eclipse (Indigo) with maven integration via the m2eclipse plugin. I configured the project as a maven project. When I r click on my project and click Run As... I'm able to see all the maven configurations (maven build, maven clean, maven install etc.) The project icon has an m indicating that it's a maven project. When I r click an go to Maven I'm able to see
Add Dependency

Disable Workspace Resolution
Disable Maven Nature
-I was told that I'd be able to see 'Update Dependencies' under the Maven menu but it seems to be missing. Is this to be expected given my Eclipse version or something? Or do I have to configure the project in some way to get 'Update Dependencies' to show up under the Maven menu?
Are you able to see the option "Convert to Maven Project" under the "Configure" menu?
This answer is based on m2e in Eclipse Helios, I haven't tried it in later Eclipse versions yet.
On the latest m2e version I installed today, I've found I need to go to Maven / Update Project... in the context menu, then select the options you want. (The Update Dependencies option seems to be fixed in the "on" position on mine.)
It may be that the current version can still be configured to show the menus as they used to be; I don't know. I say this because my old version was of a later date than the original post here, but still had the Update Deps and Update Project Conf options in the Maven menu.

Do I have to go update project first before run as maven build in Eclipse? (Refer to pics)
Update Project as seen in picture
Run as Maven build... option as seen in picture
Can I just select the run as Maven build... option? Will there be any implications if I did that?
No, it is not required to run update project before building with "Run as Maven build ...".
You usually use update project to sync the Eclipse project with the content of the pom.xml. So you use it after changing something in the pom.xml.

What does Maven Update Project do in Eclipse?
In an eclipse project, I referenced a class that was currently not in project's build path.
In the context sensitive pop-up that opens by hovering the mouse over the error, "Fix project setup" option has offered me to add a jar to the build path of the project. This jar is in my local maven repository.
However, the "correct" way to fix it is obviously by adding the relevant dependencies to my project's pom, instead of adding this jar to the build path of the project.
So is there a way to configure eclipse, so that it won't offer to add a maven repo jar to the build path, but it will offer to fix the project's pom?
This feature used to exist in m2eclipse (the predecessor of m2e), see e.g.
https://blog.sonatype.com/2010/03/adding-dependencies-using-m2eclipse/ which shows a "Search dependency for XXX" quickfix above the "Fix project setup..." quickfix.
Unfortunately it didn't make it into m2e, see https://www.eclipse.org/lists/m2e-users/msg01130.html
Make sure:
your project is fine outside of eclipse using only maven/pom, mvn
clean install (or similar) in an external shell/console
your eclipse project has maven nature
Eclipse -> Project -> Build Automatically is checked
Refresh your eclipse project
Do something in the pom.xml (save file) should trigger a build
I have the newest IntelliJ, and the create Maven project button is gone. I also cant find it in any of the lists.
See the intellij menu
You can see the difference here, in IntelliJ's Getting Started with Maven page:
https://www.jetbrains.com/help/idea/2016.1/getting-started-with-maven.html
Anyone know how to get it back?
I want it because then you get the structure, and the pom.xml file automatically.
You need to install the Maven plugin.
Go to Plugins (in IntelliJ; press shift-shift, and search for "plugins"). In Plugins window, search for Maven and install the Maven Plugins.
You can create java project and later right click on your project -> add framework support -> choose maven.
I am learning building a Java project in Eclipse using Maven. I created a Java project HelloWorld from
“maven-archetype-quickstart” template in a folder D:/maven_projects. Then to convert the Maven project to support Eclipse IDE, I navigated into the project folder and issued the commands:
mvn eclipse:eclipse and mvn package .
Then I imported the project in Eclipse and did the necessary Eclipse configurations like setting the Maven local repository in Eclipse classpath. Now the project in D:/EclipseWorkspace folder. I ran the project successfully in Eclipse printing "helloworld".
Now if I want to go on develop the project and for that reason want to add new dependencies in pom.xml in Eclipse, then the new jars are not added in classpath when I run the project.
So my question is after importing a Maven project into Eclipse how can I add more and more dependencies in pom.xml, then build and run the project? What is the recommended and efficient way to do this?
I would recommend you don't use the m2eclipse command line tools (i.e. mvn eclipse:eclipse) and instead use the built-in Maven support, known as m2e.
Delete your project from Eclipse, then run mvn eclipse:clean on your project to remove the m2eclipse project data. Finally, with a modern version of Eclipse, just do "Import > Maven > Existing project into workspace..." and select your pom.xml.
M2e will automatically manage your dependencies and download them as required. It also supports Maven builds through a new "Run as Maven build..." interface. It's rather nifty.
1.Update project
Right Click on your project maven > update project
2.Build project
Right Click on your project again. run as > Maven build
If you have not created a “Run configuration” yet, it will open a new configuration with some auto filled values.
You can change the name. "Base directory" will be a auto filled value for you. Keep it as it is. Give maven command to ”Goals” fields.
i.e, “clean install” for building purpose
Click apply
Click run.
3.Run project on tomcat
Right Click on your project again. run as > Run-Configuration.
It will open Run-Configuration window for you.
Right Click on “Maven Build” from the right side column and Select “New”.
It will open a blank configuration for you.
Change the name as you want. For the base directory field you can choose values using 3 buttons(workspace,FileSystem,Variables). You can also copy and paste the auto generated value from previously created Run-configuration. Give the Goals as “tomcat:run”. Click apply. Click run.

(I hope this answer will help someone come after the topic of the question)
Dependencies can be updated by using "Maven --> Update Project.." in Eclipse using m2e plugin, after pom.xml file modification.
Just install the m2e plugin for Eclipse. Then a new command in Eclipse's Import statement will be added called "Import existing maven projects".
answer 1
Right click on your project in eclipse
go to maven -> Update Project
answer 2
simply press Alt+F5
after updating your pom.xml. This will build your project again and download all jar files
Right Click on your project
Go to Maven>Update Project
Check the Force Update of Snapshots/Releases Checkbox
Click Ok
That's all. You can see progression of build in left below corner.
When you add dependency in pom.xml , do a maven clean , and then maven build , it will add the jars into you project.
You can search dependency artifacts at http://mvnrepository.com/
And if it doesn't add jars it should give you errors which will mean that it is not able to fetch the jar, that could be due to broken repository or connection problems.
Well sometimes if it is one or two jars, better download them and add to build path , but with a lot of dependencies use maven.
If you are getting this error :in cucumber Exception
Cucumber Exception: java.lang.ClassNotFoundException:
cucumber.io.ResourceLoader :
then add following jar file to your pom.xml
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-core</artifactId>
<version>1.1.8</version>
</dependency>
Run the maven build once and should be gone
I am in Eclipse Indigo and I have installed m2eclipse plugin. I saw in Eclipse Helios there is an option Maven in the right click menu, when I clicked on a Project, but this option is not present now.
I have installed Maven from both of the marketplace and also from adding site in Install new software option in Eclipse(Help->Install New Software).
What I am doing wrong.
This question was asked before in SO, but I tried the solution provided there.
Is this option is really not present? What I want is to enable Maven Dependency Management of a Dynamic Web Project of Eclipse.
You have to do a right click on the project, then choose Configure → Convert to Maven project
Right Click on the Project --> Configure --> Convert to Maven Project.
It will show Maven Related Options.
One way is to import the project as Maven project.
If you are trying to install in Eclipse older versions, use YOXOS Marketplace - by EclipseSource. Search for "Maven" in marketplace. You will get Maven Integration for Eclipse provided by Sonatype. Use that to install.
After installing m2eclipse plugin, go to Window -> Preferences. Check "Maven" is enlisted at the left panel list
this happened to me because I imported a parent folder as a project. so all my projects where sub directories of this parent folder and not a project them selves. after deleting them (only) from the workspace and re importing them as separate projects, maven worked fine.
