grails run-app genera casualmente: java.lang.NoClassDefFoundError: Lorg/codehaus/groovy/grails/plugins/web/async/api/ControllersAsyncApi

Question

All'avvio della mia app Grails 2.2.0, ottengo a caso il messaggio di errore come sotto, ma riesce anche casualmente ad avviarsi senza un errore. Nessuna modifica al codice, cerco solo di eseguire lo grails dev run-app più volte.

$ grails dev run-app 

Ho anche provato un grails clean prima, ma che non fa differenza; l'errore si verifica ancora in modo casuale.

Errori all'avvio:

Ambiente:

• Mac OS X Lion
• JDK 1.6.0_31

post simile, ma ancora diverso, come I' m non funziona Tomcat:

• Grails application running on Tomcat6 - Context initialization failed

Answer 1

Provare per contrassegnare la versione servlet come v3.0. Ho avuto lo stesso problema sporadico e risolto passando a v.3.0

File: BuildConfig.groovy

grails.servlet.version = "3.0" // cambiare a seconda rispetto contenitore di destinazione (2.5 o 3.0)

Dopo che graal-plugin-async-2.2.0.jar apparso sul classpath:

% home% .grails \ edera-cache \ org.grails \ graal-plugin-asincroni \ vasetti \

Answer 2

Dopo aver modificato la versione delle servlet da 3.0 a 2.5 (e viceversa) e questa eccezione a ppeared.

Ho risolto questo problema digitando:

grails clean 
grails clean-all 

Le dipendenze è stata scaricata di nuovo e l'applicazione si mise a correre.

Answer 3

Cercare di rimuovere manualmente il target nel caso in cui la pulizia non funzioni.
