standalone - Maven+Selenium+Jetty-ClassNotFoundException cuando Jetty se está apagando

selenium server standalone

Question

Estoy ejecutando una prueba de integración con Maven, Selenium y Jetty. Las pruebas se ejecutan correctamente, pero cuando el servidor se cierra, el servidor Jetty lanza una java.lang.ClassNotFoundException: org.codehaus.groovy.runtime.dgm$371 . Aquí está el rastro completo de la pila:

Answer 1

Parece que falta la maravillosa dependencia del tiempo de ejecución. Consulte http://docs.codehaus.org/display/GMAVEN/Groovy+Runtime

Answer 2

Resolví esto, agregando esta dependencia

        <dependency>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jsp-2.1</artifactId>
            <version>6.0.0</version>
          </dependency>

Answer 3

Intente agregar un stopWait a la configuración del muelle:

<configuration>
  <scanIntervalSeconds>10</scanIntervalSeconds>
  <stopKey>stop</stopKey>
  <stopPort>8005</stopPort>

  <stopWait>5</stopWait>

</configuration>

Esto asegura que el muelle se detenga antes de que se ejecute el siguiente objetivo de maven y, lo que es más importante, antes de que se complete la construcción.

Es en este caso en el que Jetty está intentando apagar cuando la compilación de Maven ha completado que verá este ClassNotFoundError.
