I am not able to create a maven project from eclipse neon/mars.
I have searched for the same problem. There are a couple of suggestions tried from the old threads, but nothing seems to be working.
Could someone please help me how to solve this issue.
Tried the following ways:
window>preferences>Maven>Archetypes>added catalog file as: http://repo1.maven.org/maven2/archetype-catalog.xml
and description as maven catalog
window>preferences>Maven>user settings> under user settings section select the settings.xml file from \conf\settings.xml
but still I get this error:

I just checked out maven based java project from svn to local box in eclipse where maven 3.0.2 is available. However while reviewing class path configuration many of dependencies are broken such as org.restlet-2.0.15.jar. Strange part is C:/Users/daeyoung/.m2/repository has that broken jar file but .lastUpdated is appended. After reading many posts from WWW, the way I understood to fix the problem is delete *.lastUpdated file then re-download it from central repo.
But when I reviewed pom.xml file there is no mention of repository (strange...) and as soon as I delete *.lastUpdated file, it comes back (e.g. org.restlet-2.0.15.jar.lastUpdated).
I am new to Maven.
I'd appreciate if someone can guide me to a right direction to fix this problem.
[update]
I created following user settings.xml file under /Users/daeyoung/.m2/ directory. I thought at least that would take care of downloading org.restlet package.
However when I ran mvn command (literally mvn) inside of project folder, system was saying..
I don't want to modify pom.xml file but rather via user settings.xml I thought I could connect to maven restlet repo and download specified target package but I am not sure what I am missing in here. I think contents of settings.xml is not correct.
I just want to say thanks to all who have given me advice. First I was not well equipped to understand the advice but more I looked at the problem/read about maven articles. It was clear what needs to be done to fix the problem.
Bottom line is I manually downloaded dependencies to ${user_name}/.m2/repository for missing jars. I configured ${MAVEN_HOME}/conf/settings.xml to point to local repository then I ran mvn validate/clean/package sequentially from eclipse via m2e plugin (or I could have done same thing from command line).
I am trying to follow some existing tutorials on Hadoop that I found online.
I have installed cloudera and am using it as the setup environment for all of the work. However when I try to create a Maven project in Eclipse, I end up having issues referencing to the quickstart archetype.
The error I get is the following:
'Creating maven-archetype-quickstart' has encountered a problem.
Could not resolve archetype org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE from any of the configured repositories
The issue seems to be linked with the ~/.m2/ folder. My settings.xml file has been set up per the tutorial and links to the online repositories.
Could not write artifact lastUpdated status /home/cloudera/.m2/repository/org/... (Permission denied)
Please note that I created the whole directory .m2/ as it did not exist. I am running out of ideas, maven is clearly installed on the VM. I am just unsure why everything is referenced back to ~/.m2/ which did not exist and had to be created (and therefore isn't populated).
Whatever help would be appreciated, thanks again for your time!
After importing a Maven GWT project into Eclipse the debugger doesn't work, complaining that it's
Unable to find ProjectName.gwt.xml on your classpath
How do you fix this error?
It turns out that when you debug some GWT project as Web Applications, Eclipse does not append the module name (i.e. the gwt.xml file) to the list of arguments. I tried adding it manually, but forgot to add the complete package name that houses the gwt.xml file. The module should have been referred to as com.company.project.Project.gwt.xml, not just Project.gwt.xml.
I found that Davek804's comment helped me: I simply deleted the debug configuration (Run=>Debug Configuration=>right click and deleted project will run
Try going to Run -> Run Configurations in the menu and then select the Classpath tab and add the missing project.
Trying to set up a new project, and running into a weird issue. I made a new app context file named backend-context.xml, I've added spring-context as a dependency, and am trying to add namespaces through the bean config file, but it's showing as 1 error, with no explaination.
If I browse into problem explorer, it states the following error:
'Unable to load schema mappings from location [META-INF/spring.schemas]'
If I browse through the Maven Dependencies I can see this file located under the spring-beans jar.
If anyone has ideas on how to fix this, that'd be awesome!
Thanks!
Ended up being caused by a local maven jar being corrupt. Found this out by uploading the code to github and trying on a different computer which worked like a charm. So, cleaned out my local repository from all spring jars and redownloaded.
Coming from Visual Studio, I'm pretty new to the Eclipse IDE.
And finding it very difficult. I seem to get error messages of the type "missing ..." a LOT.
The latest issue I'm having, where I just can't get around is this:
I"m trying to compile & run this sample project: http://code.google.com/p/gwtgae2011/
When I choose "checkout maven projects from SCM" my SCM drop down is empty...
So I just checked it out with Hg manually. No problem.
Trying Import > Existing Maven Project. Seems to read the pom.xml alright, but shows an error:
"No marketplace entries found to handle maven-gae-plugin:0.8.1:unpack in Eclipse. Please see Help for more information."
Since I can't find it through updates or market within eclipse I downloaded maven-gae-plugin (http://code.google.com/p/maven-gae-plugin/downloads/list). I figured just dropping it into the "plugins" or "dropins" folder should be enough. Apparently not so...
Question: How do I fix this error?
(I tried both 3.6 & 3.7)
Links to some good eclipse tutorials covering these kinds of topics are very welcome too!
THANKS!
maven-gae-plugin is in central repo so it should be found.
Did you set the path to your local repo? http://united-coders.com/phillip-steffensen/maven-2-part-3-configuring-eclipse-for-apache-maven-2-projects
I ran into this error, what worked for me was:
Comment the plugin
Import into eclipse
Uncomment the plugin
Discover an error in the plugin XML
Fix error found in the plugin XML
I am not certain, but it seems like this is a unclear error that something about the pom.xml is invalid.
