Create runnable jar with maven 3.1 using maven-dependency-plugin doesn't create runnable jar

Question

Using Maven 3.1
Eclipse Helios

Aspekt:

Try to create a runable jar file using maven-jar/dependency-plugins.

Problem:

Answer 1

Are you sure your java version, launched at command line, is equal or greater than that used by maven when compiling? try java -version

Answer 2

via command line, go to the parent dir of "dependency-jars" and run: java -jar program.jar

Answer 3

The simplest solution is to use maven-assembly-plugin like this:

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <!-- NOTE: We don't need a groupId specification because the group is
             org.apache.maven.plugins ...which is assumed by default.
         -->
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.4</version>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
        [...]
</project>

Answer 4

Ok, i solved the second/updated Problem:

I first startet to use eclipse with maven plugin to create the runable jar file. This runs in the described problems.

After all i tried to use maven 3.1 from console application and after all it works. Seems that eclipse maven plugin has some problems.

Not sure what's going on, but this is what my pom looks like for building a runnable jar using shade:

 <build>
        <resources>
            <resource>
                <directory>${basedir}/src/main/resources</directory>
                <filtering>false</filtering>
                <includes>
                    <include>schema.xsd</include>
                </includes>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <executions>
