Maven Problem Missing Artifact (jsf-api.jar)

Question

I installed M2Eclipse Plug-In for Eclipse. I'm not very experienced with maven. My Problem is that I can't download two Artifacts:

    13.07.10 08:53:30 MESZ: Build errors for test; org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project test: Missing:
----------
1) com.sun.faces:jsf-api:jar:2.0.0-b13

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=com.sun.faces -DartifactId=jsf-api -Dversion=2.0.0-b13 -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=com.sun.faces -DartifactId=jsf-api -Dversion=2.0.0-b13 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency: 
   1) de.studi:Studentenportal:pom:pom:0.0.1-SNAPSHOT
   2) com.sun.faces:jsf-api:jar:2.0.0-b13

2) com.sun.faces:jsf-impl:jar:2.0.0-b13

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=com.sun.faces -DartifactId=jsf-impl -Dversion=2.0.0-b13 -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there:

  Path to dependency: 
   1) de.studi:Studentenportal:pom:pom:0.0.1-SNAPSHOT
   2) com.sun.faces:jsf-impl:jar:2.0.0-b13

2 required artifacts are missing.

for artifact: 
  de.studi:Studentenportal:pom:0.0.1-SNAPSHOT

from the specified remote repositories:
  central (http://repo1.maven.org/maven2, releases=true, snapshots=false)

Here is my POM.XML:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </dependency>
  </dependencies>
  <build>

  </build>
</project>

I tried it with several versions of JSF2 with no success.

I added following to my pom.xml:

<repositories>
    <repository>
      <id>maven2-repository.dev.java.net</id>
      <name>Java.net Repository for Maven</name>
      <url>http://download.java.net/maven/2/&lt;/url&gt;
      <layout>default</layout>
    </repository>
</repositories>

But the problem is still there. Is there someting wrong with that?

Okay I got it! The project can be built. Unfortunately I don't know why. I didn't changed something :-)

Now I get only Warnings from Maven:

It doesn't look so good -.- Especially the Missing POM warnings are anxious.

Update

First I changed it to myfaces and then I added the appropriate repository to the settings.xml in the .m2 directory. Like that:

<profile>
  <id>jdk-1.6</id>

  <activation>
    <jdk>1.6</jdk>
  </activation>

  <repositories>
        <repository>
        <id>JBOSS</id>
        <name>JBoss Repository</name>
        <url>http://repository.jboss.org/maven2/&lt;/url&gt;
    </repository>
  </repositories>
</profile>

But there is still the problem that maven can't find the artifacts. Pls help :-)

Answer 1

It seems you don't have, neither in your pom.xml and its parent, nor in your settings.xml defined a list of maven repositories allowing you to access to these artifacts.

Typically, when encountering that kind of issue, my first move is to go check on mvnbrowser where are the artifacts availables. In the case of jsf-api, the reply is quite simple : you have to add JavaNet repository to your pom.xml repositories.

Answer 2

Your groupId's dependency is wrong. Enter mvnrepository and look for your dependencies there.

com.sun.faces should be javax.faces (version number might be wrong too)

If you got that dependency from some blog or web page try to find out from where is it downloading it.
