Maven build error on maven install - maven

I imported a maven project onto my eclipse. I clicked on Run As->Maven Install. But I got the following build error. Please help
plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-jar-plugin:jar 2.3.2:Could not transfer artifact org.apache.maven.plugins:maven-jar-plugin:pom: 2.3.2 from/to central(http://repo1.maven.org/maven2):Error transferring file: repo1.maven.org: Unknown host repo1.maven.org
I checked /m2/repository. But could not find anything related.

Somehow it is not able to download the required artifacts from the Maven Central repo.
A suggestion please check your network connectivity, are you behind any firewall or try to change your proxysettings.
Otherwise in the worst case try to download required artifacts manually and put them in .m2/repository (as per ur local system) and try to install again.

It should work.
Thanks

Git runner - problem to download dependency

I have one project that uses the git runner.
The command mvn package works fine on local, all dependencies are downloaded from my local nexus.
When I execute build command at the git runner environment, all dependencies from my local nexus where downloaded without problem too, but only one dependency is a problem, lets see:
[ERROR] Failed to execute goal on project sic: Could not resolve dependencies for project com.example:sic:jar:0.0.1-SNAPSHOT: Failed to collect dependencies at br.com.sspds:ojdbc6:jar:1.0.1: Failed to read artifact descriptor for br.com.sspds:ojdbc6:jar:1.0.1: Could not transfer artifact br.com.sspds:ojdbc6:pom:1.0.1 from/to Nexus (http://172.25.100.75:8090/repository/maven-public/): Transfer failed for http://172.25.100.75:8090/repository/maven-public/br/com/sspds/ojdbc6/1.0.1/ojdbc6-1.0.1.pom: No route to host (Host unreachable)
One big detail: the library ojdbc6-1.0.1.jar was developed by our team and made available manually on our nexus server.
My configuration from nexus server is into my pom.xml.
Any idea about this problem?

Can't download jar files using maven

I've been using Maven for few years now, installing it on different machines and OS's and never had problem with it. Ten days ago i installed in on new Windows 7 machine and since than
i can't find the reason why it can't download jar file's from remote repo's.
I am able to download jar file by typing URL in browser but when i run mvn install in console it start to download the jar, wait some time and then i am getting error message:
"...Could not transfer artifact org.primefaces:primefaces:jar:5.0 from/to central (http://repo.maven.apache.org/maven2):
GET request of: org/primefaces/primefaces/5.0/primefaces-5.0.jar from central failed:
Read timed out ... java.net.SocketTimeoutException: Read timed out".
I read all articles here, tried everything but without success.
Can anyone help?
Primefaces artefacts are not in Maven Central. You need to setup a supplemental repository to get those artifacts. I would suggest to start using a repository manager.

Maven - unable to download dependencies behind Proxy Error Code - 307 Temporary Redirect

I am using Maven to run a Java project. My issue is that I am not able to download the dependencies. It is giving the following error
[ERROR] Plugin org.apache.maven.plugins:maven-surefire-plugin:2.7.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-surefire-plugin:jar:2.7.1: Could not transfer artifact org.apache.maven.plugins:maven-surefire-plugin:pom:2.7.1 from/to central (http://repo1.maven.org/maven2): Failed to transfer http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-surefire-plugin/2.7.1/maven-surefire-plugin-2.7.1.pom. Error code 307, Temporary Redirect -> [Help 1]
The settings.xml is properly configured with the proxy details (since I am behind a proxy) Still, I am not able to access the maven repo to download.
UPDATE: Thanks a lot landal79.I revisited this issue after some time. Still this issue gives me a nightmare.
Currently, I am not able to create any Maven Project. I am 100% sure this is due to a proxy issue. But not able to
nail it down to where exactly the issue.
When I try creating a project selecting an archetype, I am not able to create a maven project. I am getting the below error
"Could not resolve archetype org.apache.maven.archetypes:maven-archetype-quickstart:RELEASE from any of the configured repositories.
Could not resolve artifact org.apache.maven.archetypes:maven-archetype-quickstart:pom:RELEASE
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-
quickstart:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-quickstart/maven-metadata.xml in local (C:\Users\rrr.m2\repository)
Failed to resolve version for org.apache.maven.archetypes:maven-archetype-quickstart:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-quickstart/maven-metadata.xml in local (C:\Users\rrr.m2\repository)"
I try creating this project through Eclipse. The settings.xml point to the right proxy ( cross checked with the Network connections dialog (window ->General->NetworkConenction Dialog). But the issue still persists.
So what I did was installed standalone Maven and create a maven project from command prompt. To my surprise,I am not able to download the archetypes in Maven Repo though other plugins are getting downloaded (Surefire plugin and JUNit jar for example)
Is there any work around to resolve the archetype download issue?
I tried your solution, but the issue still persists. When I create a simple maven project (without using any archetypes) I am getting "Unable to build Project " Error
PS: The proxy settings are defined in settings.xml and they are correct. Also, the eclipse proxy settings are correct (Since I am able to install plugins from Eclipse MarketPlace)
Eclipse experts - please help me resolve this issue. Thanks a lot in advance for help.
Thanks

Jenkins could not resolve dependencies

I have a problem with jenkins version 1.500. i am trying to build a project with a dependency to another project of mine.
The error is:
[ERROR] Failed to execute goal on project projectname: Could not resolve dependencies for project projectname:jar:1.0.0: Failure to find reference-project:jar:1.0.0 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
If I build this project via console and Maven, the whole projects build succeed.
I checked the dependency jar file in the repository, it is there at the right place.
Does Maven have a own repository or did I miss something?
But under the Jenkins system settings, I chose "Default(~/.m2/repository)" and I did not check the checkbox "use own repository" at the project settings. Any ideas?
UPDATE
I created a extra job for the dependency in jenkins and called the Maven goal install and then everything works fine. Before this step I installed the dependency via Console and mvn install.
Why is there a difference? (i tried the given solution with delete and reinstall, but this did not help)
Simple solution delete the folder from the ~/.m2/repository which represents the artifact you've written about. ~/.m2/repository/${groupId}/... and rebuild. That happens sometimes if you have some problems during download of the artifact etc.
I too have similar problem and tried deleting the folder in ~/.m2/repository/
still its now downloading dependencies from remote repository location to local
