My POM-File looks like that:

        </dependency>
        <dependency>
            ....
        </dependency>
    </dependencies>
</project>

In my project I am using a bunch of jar-Files (like SWT, Log4j and so on, but also own libraries). But all of these are added to my local repository (my own libs I added by mvn install:install-file ..) and in the depedencies of my POM.. In Eclipse my Project "knows" all imports, the code looks fine, has no errors or something like that..

If I only run

mvn package

and then executing my jar

java -cp target\JImp-0.0.1-SNAPSHOT.jar de.my.path.JImp

he throws a ClassNotFoundException because he couldn't find a class of my own lib.. But this lib is added to the local repository and to the depedency in my POM-File.. :/

Maybe you could help me..!!

I appreciate your help very much!

for mvn deploy issue

You need to provide repository address where you want to deploy you arfifact in pom.xml like below

<distributionManagement>
  <repository>
    <id>mycompany-repository</id>
    <name>MyCompany Repository</name>
    <url>your repository url</url>
  </repository>
</distributionManagement>

To run maven artifact jar, you need to use mvn exec command, then only it includes all jars mentioned in pom.xml in your classpath. See example below

mvn exec:java -Dexec.mainClass="de.my.path.JImp"

I found: "Maven will first attempt to use a local copy of the specified artifact. If that artifact does not exist in the local repository, it will then attempt to download from a remote repository" (http://maven.apache.org/pom.html#Repositories) Why do I have to define a repository when I want to use mvn deploy? – mrbela Dec 16 '14 at 10:20
And is it enough to invoke mvn package or do I have to run the whole default life-cylce (validate, compile, test, package, integration-test, verify, install, deploy) by invoking mvn deploy – mrbela Dec 16 '14 at 10:23

`mvn deploy` command get used to upload ***your artifact*** to remote repository. If you just want to add in local repository, then `mvn install` will do. – Adi Dec 16 '14 at 10:24

for your second question, it runs as life cycle, so when you execute in lifecycle phase, say `package`, all phases before it gets automatically executed. – Adi Dec 16 '14 at 10:25
Thank you very much for your help!!! To my second question: Which phase should be invoked by default? I know, it depends on what I want, but are the phases "integration-test" and "verify" usefull to find errors or something like that? I think that I don't need the phases "install" and "deploy", because I don't use my artifact in other projects (locally and from my remote repository) – mrbela Dec 16 '14 at 10:41
as you said, it depend on need, but i found `package` most helpful while doing local development, it cleans project, compile all resources, executes all unit tests and then builds jar artifact. – Adi Dec 16 '14 at 10:46
