Maven Could not find artifact after downloading from Nexus

we have got a problem. I set up job on jenkins and while building a project it fetches artifacts from nexus. But even though it downloaded them job failed with artifacts could not be found. It happened only to artifacts we manually imported to the nexus.
Any hints?

I think it has not downloaded completely yet, you can check in ~/.m2/repository for dependency.
Because its showing only "downloading" in actual case it will appear downloaded message.
first check for the n/w settings and internet.
if n/w is not the issue delete the ~/.m2 folder and retry once again

Do you see the dependency in Nexus?
Does Information in pom file in nexus correspond to your pom?
http://nexusUrl/nexus/content/repositories/central/checkstyle/checkstyle/4.1/checkstyle-4.1.pom
<?xml version="1.0"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>checkstyle</groupId>
<artifactId>checkstyle</artifactId>
<version>4.1</version>
<dependencies>
...
</dependencies>
</project>
and in your pom:
<dependency>
<groupId>checkstyle</groupId>
<artifactId>checkstyle</artifactId>
<version>4.1</version>
</dependency>
and check your settings for access to Nexus (settings.xml).

Install manually jar file

Install manually jar file into repository.
I want to install this SDK as maven dependency.
https://developer.intuit.com/docs/0100_quickbooks_online/0400_tools/0005_accounting/0200_java/0002_installing_the_java_sdk_for_quickbooks
I tried this:
mvn install:install-file -DgroupId=com.intuit.code.devkit.v3 -DartifactId=ipp-v3-java-devkit -Dversion=2.5.0 -Dpackaging=jar -Dfile=c:\lib\ipp-java-qbapihelper-1.2.1-jar-with-dependencies.jar
But I get

When I browse my local repository I can't find any jar file into the directory. Can somebody give some advice how I can fix this?

What I've done in the past to make this work is:
Copy the jar file(s) of interest to a temp folder i.e. project root/tmp
Run the following command (adjusting the parameters accordingly) in the command line from the the project root directory:
mvn install:install-file -Dfile=tmp/<filename>.jar -DgroupId=intuit.code.devkit.v3 -DartifactId=ipp-v3-java-devkit -Dversion=2.5.0 -Dpackaging=jar -DlocalRepositoryPath=<repo path> (i.e. src/dependencies/jars)
After that command you should see a src/dependencies/jars/com/... directory with maven artifacts under it
Add dependency to your pom.xml
<!— <project> is the parent element —>
<repositories>
<repository>
<id>system-jars</id>
<url>file://${basedir}/src/dependencies/jars</url>
</repository>
</repositories>
<!— Add the dependency —>
<dependency>
<groupId>com.intuit.code.devkit.v3</groupId>
<artifactId>ipp-v3-java-devkit</artifactId>
<version>2.5.0</version>
</dependency>
Perform a maven clean and package. Verify the classes are included in the end artifact and then delete the tmp directory once everything is correct.

Downloading metadata information from Artifactory

At the company I work for we are using artifactory like tool of repository management. Now I'm working on a modular project that look like at the following:
Now, I realized that each day the first time that I try to build my application through the command
jetty:run
I get the following information:
[INFO] Downloading: http://myRepo/artifactory/repo/it/myCompany/services/0.0.1-SNAPSHOT/maven-metadata.xml
[INFO] Downloaded: http://myRepo/artifactory/repo/it/myCompany/services/0.0.1-SNAPSHOT/maven-metadata.xml

[INFO] Downloaded: http://myRepo/artifactory/repo/it/myCompany/model/0.0.1-SNAPSHOT/maven-metadata.xml

[INFO] Downloaded: http://myRepo/artifactory/repo/it/myCompany/test/0.0.1-SNAPSHOT/maven-metadata.xml
I think that these xml files are converted in maven-metadata-repo.xml in the corrisponding folder inside the local repository. For example the file maven-metadata-repo.xml of the model project contains the following info:
<?xml version="1.0" encoding="UTF-8"?>
<metadata>
<groupId>myCompany</groupId>
<artifactId>model</artifactId>
<version>0.0.1-20140417.095713-1</version>
<versioning>
<snapshot>
<timestamp>20140417.095713</timestamp>
<buildNumber>1</buildNumber>
</snapshot>
<lastUpdated>20140512073542</lastUpdated>
<snapshotVersions>
<snapshotVersion>
<extension>pom</extension>
<value>0.0.1-20140417.095713-1</value>
<updated>20140417095713</updated>
</snapshotVersion>
<snapshotVersion>
<extension>jar</extension>
<value>0.0.1-20140417.095713-1</value>
<updated>20140417095713</updated>
</snapshotVersion>
</snapshotVersions>
</versioning>
</metadata>
Now I want to ask you Why i get the informations of download only the first time (each day) that i run the command jetty:run?
Also I configured the snapshot repository in artifactory in this way
Is this the reason of these continuous download?

This is related to the way Maven is checking whether there is an updated SNAPSHOT version of your dependencies (Maven3 is using unique SNAPSHOT versions). Maven downloads the maven-metadata.xml file and checks if it has the latest SNAPSHOT version cached in the local Maven repository or it needs to download a newer one from Artifactory.
The default update policy for SNAPSHOTS is checking once a day ("daily"). You can configure this policy in your settings.xml file, for example:
<repositories>
<repository>
<id>central</id>
<url>my-server-url</url>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
<releases>
<enabled>true</enabled>
<updatePolicy>daily</updatePolicy>
</releases>
</repository>
</repositories>
Possible values for are: "always", "daily" (default), "interval:XXX" (in minutes) or "never" (only if it doesn't exist locally).

Maven is not using repo1, it's going over to maven.glassfish.org and failing my build

I have this repo section:
<repositories>
<repository>
<id>Repo1</id>
<url>http://repo1.maven.org/maven2</url>
<releases>
<enabled>true</enabled>
<checksumPolicy>fail</checksumPolicy>
</releases>
</repository>
<repository>
<id>EclipseLink</id>
<url>http://download.eclipse.org/rt/eclipselink/maven.repo</url>
</repository>
</repositories>
and this dependency:
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-client</artifactId>
<version>1.9.1</version>
<scope>compile</scope>
</dependency>
Why is maven continuously going to download.java.net and maven.glassfish.org ? It's not in my poms anywhere

EDIT:
As a debug step, I've nuked ~/.m2... I don't know what is going on, but this build used to work.
MOR EDIT:
Ok, so I should have mentioned, the repositories section is in the parent pom and the dependency is in the child pom. If I put the configuration into one big pom it works. Two poms, it fails. What the heck??
EVEN MOR EDIT:
This is absolutely crazy where maven is getting the extra repositories at, I even checked the artifact poms. Anyway, here is my solution to the unexplained behavior. Put this in my settings.xml:
<settings>
<mirrors>
<mirror>
<id>central-mirror</id>
<url>http://repo.maven.apache.org/maven2</url>
<mirrorOf>*,!eclipselink</mirrorOf>
</mirror>
</mirrors>
</settings>
This forces maven to use central, except for when I'm using the eclipselink repo. Sigh, argh!

This forces maven to use central, except for when I'm using the eclipselink repo. This doesn't answer my question, but it's a workaround for whatever crazy reason maven is contacting these external repos.

Repositories can also be specified in your settings.xml and other dependencies' poms. Regardless of which repositories you do directly or indirectly name, maven doesn't guaranty the search order for those repositories, If maven happems to find a bad artifact in one repository, it fails (obviously) and doesn't try any other repositories.
If you can find a good version of the artifact that's giving you trouble, you might try manually placing that artifact in your local .m2 repository.

Maven - webstart could not be activated

I am trying to launch a Scage Project. I never used maven before.
I created a pom.xml file and downloaded the files with intellij
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

This worked just fine. I also created the main file, as pointed in the tutorial
import net.scage.ScageScreenApp
import net.scage.ScageLib._
import net.scage.support.Vec
object HelloWorldExample extends ScageScreenApp("Hello World") {
private var ang = 0f
actionStaticPeriod(100) {
ang += 5
}
backgroundColor = BLACK
render {
openglMove(windowSize/2)
openglRotate(ang)
print("Hello World!", Vec(-50, -5), GREEN)
}
}
As pointed in the tutorial I have to use this command to build it mvn clean package -Pwebstart

Now the output is a .jar file instead of a .jnlp file, also nothing happens if I doubleclick the .jar file.
Any ideas what went wrong?

You are missing the webstart profile in your pom.xml
look at the pom.xml inside the scage example project: https://code.google.com/p/scage/downloads/detail?name=scage-example-project.zip&can=2&q=
it is quite large, but among others has thing it has the profile specified
