Archivos duplicados en el archivo .war de Gradle

Question

Tengo un problema de archivos duplicados con mi script de construcción de Gradle.

Mi estructura de directorios es el estándar experto, además de algunos directorios adicionales para diversas configuraciones de construcción:

/src/main/java 
/src/main/resources 
/src/main/dev/resources 
/src/main/prod/resources 

Los archivos de /src/main/resources y /src/main/dev/resources aparentemente están manejados por tanto tarea de la processResources y la war, y terminan en el archivo .war dos veces. ¿Cómo puedo evitar que esto ocurra sin excluir manualmente cada archivo en la configuración de guerra?

Todo mi build.gradle se incluye a continuación; La nota buildEnvironment se establece en dev de forma predeterminada, pero también podría ser prod.

No he probado la configuración aquí, pero creo que es porque va a añadir a main.resources.srcDirs += "src/main/$buildEnvironment/resources" sourceSets. Al añadir este que tiene ahora los siguientes sourceSets si buildEnvironment = 'dev':

• src/main/java
• src/main/resources
• src/main/dev/recursos

Esto significa que si que ha llamado un recurso myfile.txt tanto en src/main/resources y src/main/dev/resources se podrían obtener los siguientes archivos:

• WEB-INF/classes/MyFile.txt
• WEB-INF/classes/dev/MyFile.txt

Para solucionar este problema, sólo podía mover sus recursos dev/prod fuera del src/main, ex. de esta manera:

• src/main/java
• src/main/resources
• src/dev/recursos
• src/prod/recursos

y utilizar los siguientes sourceSet vez :

main.resources.srcDirs += "src/$buildEnvironment/resources" 

Luego, todos los recursos dev/prod anularán la res las fuentes en src/main/resources.
