In the SVN repository browser I can right click on 'trunk' which gives me the option to 'checkout as maven project'. I have two problems:
When it checks out the project, it is giving it the directory structure mavenxxxx > trunk > src. How do I configure this so it is MyProjectName > src and skip the trunk folder and only check out it's contents?
When I check out my project it appears as a java project when I want it to be a web application project, is it supposed to be picking up that it is a web application from my pom file, or do I have to follow any other additional steps to configure it?
Thanks
Check Out From SVN
It sounds like you are not selecting the "trunk" folder when you checkout your project. If your project name is Mavenxxxx and you select 'Mavenxxxx" when you check out, then you will get see the behavior you've described.
In your post, you said you did, in fact, right-click on "trunk." So I would suggest checking out your project another way. Try this:
File > New > Other...
Type "SVN"
Select "Project from SVN"
Click "Next" then choose/create your repository and click "Next"
Click Browse... and navigate to your project
Highlight the "trunk" folder and click "Ok" then click "Finish"
In the popup window, choose "Check out project with the name specified"
Click "Finish"
If that doesn't work, then there must be folder at the root level of your project named "trunk." As in Mavenxxxx > trunk > trunk.
Enable Web Application Project
To answer your question:
...is it supposed to be picking up that it is a web application from my
pom file, or do I have to follow any other additional steps to
configure it?
What you are trying to do is change the nature of your project. That can't be done from the POM file.
Instead, right click your project, go to the "Project Facets" section.
That is where you should be able to set it as a web application project.
If you see a link that says, "convert to faceted form..." then do that. Next, choose the facet related to WebApps. I don't have my eclipse setup for Web Application projects so I can't tell you the exact wording that you'll see. I think you need the Eclipse IDE for Java Developers to see that and I have the J2EE version.
I hope that helps...
You mentioned that you're using Subclipse, I highly recommend using Subversive SVN Team Provider over Subclipse. gmale's instructions should work from that point on.

I'm trying to import a Java project from my teams subversion repository. So I go through the import GUI for subversion, select my repository and the project, then choose to check it out as a project into the workspace.
However, the project now appears in my workspace simply as a folder:
Trying to add a new class tells me "source folder is not a java project". Is there something I am missing? Thanks.
Check out as a project only does what you want if you have checked-in the Eclipse .project, .classpath files etc. In that scenario those files get checked out and configure the Eclipse project. Otherwise you are just getting an Eclipse "Simple Project" which does not have the Java tools configured.
I assume you do not have those Eclipse files in your repository, so you want to use the other option that lets you run the Eclipse Create Project wizard as part of the checkout. This lets you choose the project type and setup some of the configuration. You can skip most of the configuration since you can also do that after the checkout finishes if you prefer.
See: Subclipse Checkout Documentation
I'm wondering why I can't see following folders in src node in Package Explorer
src/main/java
src/main/resources
src/test/java
src/test/resources
I can access those folders as direct children of the project and they exist in the file system.
I'm using Spring Tool Suite (STS of Eclipse).
Maybe I can configure Eclipse somehow ?
I have solved this issue by below steps:
Right click the Maven Project -> Build Path -> Configure Build Path
In Order and Export tab, you can see the message like '2 build path entries are missing'
Now select 'JRE System Library' and 'Maven Dependencies' checkbox
Click OK
Now you can see below in all type of Explorers (Package or Project or Navigator)
src/main/java
src/main/resources
src/test/java
Eclipse filters out folders that are marked as source from the "raw" folder path. That is, they are visible only as source folders:
If you can't see them in either place, then they
are either filtered out in the settings: check your settings for Package Explorer (the Package Explorer bar, downwards menu arrow -> Filters...)
or they were created externally and Eclipse haven't noticed them: Refresh your project in this case.
or they don't exist: right-click on the project, select New->Folder and input the path, e.g. src/test/java (not "Source Folder"). After you use Maven->Update Project... on the project, they will be automatically added as source folders, provided you have the default configuration.
Now, as I said, those folder will only be used as source if you preserved the default configuration in your POM. If you defined other resources and/or testResources, those will be used instead. In general, Eclipse m2e synchronizes Eclipse's project source folder configuration with what's in your POM.
EDIT: maybe this is unclear - see those folders at the top? The ones labeled with the /-separated paths? These are your folders. These are the same folders that you would expect to find in main and test, just represented differently.
I used to get the same problem, but solved it by pointing to the right jre used for the project.
Right click on the project
properties
java builpath
see the jre selected
edit it
select alternate jre
installed jre
select the right one
ok
After changing right click on project>maven>update project
Hope it helps.
Attaching screen shot.
If you are looking for Simple/quicker way, you can follow this solution.
Right click on your project.
Goto > Build Path > Configure Build Path > Java Build Path
Goto 'Source' tab, there, you can see like <<your_project_name>>/src/main/java(missing).
Click on it and remove.
Click on Apply and Close.
Now, right click on project and >New > Source folder > add source folder "src/main/java".
happy learning and do not forget to upvote :)
I had the same problem, I changed my Eclipse project view from Package explorer to Project Explorer.
After 2 hours of trying everything...
Just go on window -> show view -> project explorer
and in project explorer you can view of all files solution
I had a similar issue when I checked out a web project from a github repo on my eclipse. src/main/java was directly inside the project root in Package Explorer. My expectation was that src/main/java be visible inside a source folder "Java Resources". There were few things which I did to achieve this.
Right click on Project > Build Path > Configure Build Path..
Select filter "Java Build Path" and click on Tab "Libraries"
Verify your "JRE System Library". If it is not pointing to your latest JDK, then you can click on Edit Button and follow the subsequent dialog boxes to select most appropriate JDK home path in your system.
Once done click Apply, Apply and Close, Finish to close all the associated open boxes for the current filter.
Select filter "Java Compiler" and ensure your JDK Compliance points to correct JDK. Click Aapply
Select filter "Project Facets". Ensure both Java and Dynamic Web Module is selected with correct version.
Click Apply and Close.
Source folder "Java Resources" gets created with src/main/java in it when viewed in Project Explorer.
Navigate > Show In > Package Explore
Right click the Maven Project
-> Build Path -> Configure Build Path
Go to Order and Export tab,
you can see the message like '2 build path entries are missing'
Now select 'JRE System Library' and 'Maven Dependencies' checkbox
Click OK

I used this tutorial to create my maven web project http://crunchify.com/how-to-create-dynamic-web-project-using-maven-in-eclipse/ and eclipse did not create src/main/java folder for me. When i tired to create the source folder src/main/java eclipse did not let me. So i created the folder outside eclipse in the project directly and then src/main/java appeared in eclipse.
I was not able to see the build path option in the properties as well. Also the
src/main/java
was not visible in Project Explorer. below solution worked for me
Go to Project root
Select "Project facets" from Properties
Check "Java"
This fixes the issue
If none of the answers worked for you. You might be in the wrong "Window". I was in "Package explorer" and switching to "Project Explorer" showed me the folders.
Right click on the project > Build Path > Configure Build Path > Source > Add Folder > Select src/main/java > apply and close > refresh the project.
This error happens when there are no files inside /src/main/java
Just make some empty files inside and the problem will go away.
A side note: lots of version control systems (mercurial for example) do not commit folders if there are no files inside.
After creating the project go to properties --> build path --> configure build path --> order and export tab and check jre and maven dependencies. You will then have the folder.
Right click on eclipse project go to build path and then configure build path you will see jre and maven will be unchecked check both of them and your error will be solved
My problem was kind of the same at first and then a little different in the sense that when /java folder showed up, it was deep down in a nested folder somewhere in src/main/resources/java.
Initallially the problem was being in the Package Explorer and not in the Project Explorer as many people have talked about. So,
a. right-click on your project root
b. show in, and select Project Explorer
However, the main problem was I missed to notice a checkbox at the second step of Maven Project Creation from the wizard. That got me created a complicated structure and not a clean direct one.
Once I marked it checked I got a clean project structure as what asked.
I was also facing the issue but I open POM xml file and keep it open. Wait for some time till maven read pom then Automatically it will come.
I tried all the solutions mentioned in this post but none of them worked for me.
The solution for me was to go to build-path and then into Source tab. I found src/main/java folders present there and there was no error. I double clicked on this folder and a window opened like this:
Do not make any change and click on Finish. The folders will appear suddenly.
My Eclipse does not show the 'Java Build Path' option in my Java project's properties. The properties screenshot is attached below. What might be the reason for this? On the left side there should be an option for 'Java Build Path'.
To resolve this issue follow the below options
1) Go to Project root
2) Select "Project facets" from Properties
3) Check "Java"
This fixes the issue
I was in the same situation, and found two different solutions for this.
Right click on the src folder and check if you can see the option to configure the build path. After that, right click on the project and do Maven > update project.
If this does not work,
Right click on the project > properties > project facets and click on the link saying convert the project into faceted project.
Right click on the project, hit Refresh and check if you get the option to configure build path now.

How do I add a builder to a given project
OR check this post
Eclipse adding your own build command
Build your project using Project->Build Project in Eclipse .This will automatically adds build path to your project.
I had to delete my maven .m2/repository folder and that made my build path reappear.
I had the same problem when trying to compile a project. The solution was to go to "run configurations" and choose the right Runtime JRE.
Make sure your project's root directory contains .classpath and .project file.
The .classpath file should look like this -
The .project file should look like this -
With these changes in place you should be able to see the proper folder structure as well as the "Build Path" option when you right-click the project.
If it was working fine previously and now its not, check whether you are in Enterprise tab or the Navigator tab, because if you're in the Navigator tab it won't work.
I am struggling with maven in Eclipse even though I have m2e.
I checked out a maven project from CVS and cannot navigate anywhere. If I try References > Project, I get a pop up saying:
"Problems opening an editor Reason: services does not exist".
services is the name of the main project, which has sub projects within it. It all builds successfully so I am not sure why Eclipse does not work.
I suspect something related to classpath but have no idea how to edit it since it is not available from the project's properties. I actually tried to manually create a .classpath file but it did not help.
I also converted the project to a maven project but that did not help either.
Any ideas? I am using Eclipse JUNO.
I figured out my issue. I had to check out the project from CVS. Then (that's the important part), perform a maven import of an existing project within eclipse. That created maven "ready" projects where I could use all of the IDE's functionality.
Yes, you're right. If you import directly from a repository, hovering, linking and opening declarations isn't gonna work. Your solution is right, although another one more direct is use the "File->New->Other->Maven->Checkout Maven Projects from SCM". If then, you have problems because you can't select any SCM type, check Checkout Maven project from SCM - no connectors. If with connectors installed you still have problems: http://forum.springsource.org/showthread.php?102665-SCM-types-not-available-in-Checkout-Maven-Projects-from-SCM.
If you have checked out project from svn, project checked out is not generally a eclipse project thats why general functionality of eclipse does not work for the same.
To achieve the same functionality of eclipse like eclipse reader and all other shortcuts,we have to convert the checked out project to eclipse project.
Steps to Convert checked out project to eclipse project:
Right Click on Checked-out Project.
Point to Configure.
Click on Convert to Maven Project.(if checked out project is maven project)
These steps will convert the project to Maven project.
All the eclipse functionality will work for the same.
In addition to ensuring that the projects are configured as Maven projects, you may also go to Project Properties (right-click on the project in Package explorer) > Project References, and add projects in the workspace that the selected project may have references to.
I had this problem, too.
It looks like after a search-in-workspace Eclipse opened a wrong file.
I pressed Strl+Shift+H (Open Type in Hierarchy), typed in the class name, and opened it. The file opened in a new tab, and everything was navigable again.
The difference in icons is:
I have tried posting this question on the Eclipse Maven forums but it seems very quiet there so here goes...
My setup:
-Eclipse Indigo Java EE bundle
-m2e
-Subversive
We have a fairly simple multi module maven project on our repo. It has a parent project/pom and 3 child projects/poms.
Steps I am taking to import:
1) I import the project by using "import->import->->Maven->Check out Maven Projects from SCM".
2) On the next dialogue box I select svn as the SCM URL type and enter the rest of the repo URL. I leave the check boxes checked for "Checkout Head Revision" and "Checkout all Projects" and under "advanced" I leave the check box "Resolve Workspace Conflicts" checked too. I do not enter anything under "Profiles" or "Name Template".
3) On the next dialogue box I leave "Use default Workspace location" checked and leave "Add projects(s) to Working set" unchecked and click "finish".
4) I wait a minute or so for the next dialogue box to appear. It asks me to select maven projects and has a file structure as it should be-parent project/pom and 3 child projects/poms with a checkbox beside all 4 items. I have tried to select either just the parent, just the children or all 4 without success.
5) When I select just the parent and uncheck the children above, the project appears to be imported. The parent appears in the project explorer and the three children appear as sub-folders of the parent with each having a pom.
6) If I right click on the parent, I get a Maven item in the context menu and indeed I can "run as->Maven build, install etc.." ON THE PARENT ONLY. The Child projects have no such Maven context menus nor the ability to "run as->Maven x".
If I try to import all 4 projects in step 4 above, it imports with the same structure as outlined in 5 above but with the children appearing additionally as separate "independent" Maven projects (with errors).
Ultimately I just want to import the multi-module Maven project and be able to deploy it on my Eclipse Tomcat installation, so if I change a file in one of the child projects (called frontend) the change will be deployed quickly and I can check the effect out in a browser.
Thank you very much for any and all help with this issue! I am happy to answer any further questions to help trouble shoot the problem.
My projects occasionally also lose this ability (though they have it right after import). Usually it helps to refresh Maven configuration, refresh/clean projects, or restart Eclipse. Note that it should still be possible to run it the long way, so "Run -> Run Configurations -> Maven".
I'm running Helios SR 2, m2e 1.0.0.20110607-2117.
Pretty sure each module would have to have it's own .project settings that you would need to commit.
Did you install the m2e WTP extension? At least in theory that should be a better option than tinkering with project settings outside of Maven/m2e control.
I probably explained the problem poorly in my initial question. The main problem was that I was not able to deploy the webapp component of the multi-module maven project to Tomcat. I was making a couple of basic errors:
I was importing the parent project without selecting the children, assuming Maven would get them all and that would suffice, but it did not: I had to select the parent and all children when importing as Maven project from svn.
I then failed to convert the webapp part of the project to a faceted type, and further failed to select "dynamic web app". I needed (according to a colleague) to then select version 2.5 to avoid incompatibilities with older servlet containers. (not sure how relevant this is to Tomcat 6, which is what I use).
Once this was done I had the parent project and 3 subfolders and also the 3 child projects in their own right appearing in the project explorer (but on file system they all exist under the parent project, as it should be). I could then right click on the webapp module (the eclipse project explorer project, not the subfolder) and run as Maven project (clean, build etc.).
I could then right click and "run on server". I had an error upon publishing about various files being out of sync. I just refreshed the child projects in eclipse and then they would publish successfully.
Eclipse has so many versions, with so many incompatible plugins etc. that it gets confusing very quickly-lots of the tutorials are highly specific to particular versions etc.
Thanks for helping anyway guys.
