Question

quelqu'un Espérant peut me aider avec cette étrange. Je suis en train de lancer le plugin webstart mais il ne semble pas être en mesure de trouver la classe principale dans le pot étant produits. Le pom est aussi simple qu'il peut obtenir, et le test existe de classe, et est compilé et placé dans le pot. Quelqu'un peut-il s'il vous plaît me diriger dans la bonne direction? 

<project>
  <modelVersion>4.0.0</modelVersion>
  <name>Desktop Components</name>
  <groupId>com.test</groupId>
  <artifactId>test</artifactId>
  <version>1.0</version>
  <packaging>jar</packaging>
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo.webstart</groupId>
        <artifactId>webstart-maven-plugin</artifactId>
        <executions>
          <execution>
            <phase>process-resources</phase>
            <goals>
              <goal>jnlp-download-servlet</goal>
            </goals>
          </execution>
        </executions>

        <configuration>
          <jnlpFiles>
            <jnlpFile>
              <jarResources>
                <jarResource>
                  <groupId>com.test</groupId>
                  <artifactId>test</artifactId>
                  <version>1.0</version>
                  <mainClass>Test</mainClass>
                </jarResource>
              </jarResources>
            </jnlpFile>
          </jnlpFiles>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

Ceci est un problème MainClass pour JNLP

Vous avez besoin de quelque chose comme ceci 

<configuration>
   <jnlp>
      <mainClass>com.test.Test</mainClass>
   </jnlp>
<configuration>
