Можно запустить файл JAR.Ошибка JNI после сборки maven.Classpath может быть сломан

Question

Я пытаюсь запустить файл .jar, созданный с помощью maven.Когда я запускаю свой проект в InteliJ IDE, он работает нормально, но когда я строю его с помощью maven, я не могу его запустить.

Команда, используемая для запуска run:

java-cp target \ xmpp-server.jar com.wedevol.xmpp.server.EntryPoint

Вывод команды:

c:\Repos\remindanyoneserverapp>java -cp target\xmpp-server.jar com.wedevol.xmpp.server.EntryPoint
Error: A JNI error has occurred, please check your installation and try again

Полагаю, это проблема с classpath.Я попытался сгенерировать classpath с помощью IDE, но не могу его найти ... Пожалуйста, дайте какой-нибудь совет, как начать с classpath, если это так.Возможно, лучше настроить Maven для сборки всех зависимостей в jar.

Answer 1

pom.xml пришлось обновить следующим образом:

a

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>fully.qualified.MainClass</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
</plugin>
