java.lang.OutOfMemoryError: Errore spazio permGen

Question

Ho letto tutti i tipi di soluzioni per questo. Un link in un commento in

Dealing with “java.lang.OutOfMemoryError: PermGen space” error

è il migliore che ho trovato finora. Piuttosto complicato da seguire però.

Il punto è che ho ricevuto questo errore semplicemente compilando un progetto con Maven.

A mia conoscenza non esiste un server di applicazioni finora. COSÌ cosa sta succedendo?

E cosa posso fare?

Questo è il mio errore:

Exception in thread "main" java.lang.OutOfMemoryError: PermGen space 

Answer 1

Si prega di vedere questa domanda: "java.lang.OutOfMemoryError: PermGen space" in Maven build

(o)

Si prega di consultare questo link: http://vikashazrati.wordpress.com/2007/07/26/quicktip-how-to-increase-the-java-heap-memory-for-maven-2-on-linux/

If you get an error OutOfMemory error while doing mvn site, because of all the reports that you are generating, just increase the heap size for maven2. The way to do that on linux.

In your mvn.sh add this as the first line after the copyright and other comments.

export MAVEN_OPTS=”-Xmx512m”

note than Maven 2.0.6 onwards some users have reported that the double quotes give problems, hence you might want to use

export MAVEN_OPTS=-Xmx512m
