Maven - Error de compilacion con MAVEN2

Tengo tres proyectos
1- Root
2- Java
3- Web

Orden de dependencias
Root<--Java<--Web

Por alguna razón, que no entiendo, tengo que correr el maven reiteradas veces antes que pueda generar el WAR como corresponde. Suele tener distintos errores. Entre ellos el mas recurrente es el que adjunto abajo.

Estoy trabajando con maven 2.0.9 JDK/JRE1.4 y Eclipse.
Lamentablemente no puedo subir la version de ninguno de estos.
Las opciones de maven son(variables de entorno) MAVEN_OPTS -Dfile.encoding=cp1252 -Xmx1024m -Xms512m

Nota: A veces, y solo a veces, veo que haciendo un CLEAN al proyecto desde el eclipse parece que sale todo OK. Pero tampoco es que sale siempre.

La pregunta del millon es ¿Porque después de tirar vaaarias veces el intall de maven logra hace el SUCCESEFUL y no a la primera?




el error:

C:\User\JOSE\Workspace Brasil\desWeb>mvn install
MAVEN_OPTS=-Dfile.encoding=cp1252 -Xmx1024m -Xms512m

Hola Jose,

te comento que en mi caso suelo generar el (JAR o WAR) independientemente y no tengo problemas, para ello utilizo el Eclipse Helios e integro el Maven en este IDE.

Saludos

Hola Jose,

Parece que tienes un problema a la hora de copiar recursos estaticos. Yo miraria dos cosas, por un lado la configuracion del maven resources plugin, que se encarga por lo general de empaquetar estas cosas, y por otro lado, la salida del comando $mvn clean install -X -e para ver la informacion de depuracion completa a ver si arroja mas informacion
