sonar findbugs heap tamanho

Eu sou novo no sonar. Eu estou correndo sonar de Jenkins com sonar pulgin.

Quando estou correndo de Jenkins estou ficando fora da exceção de memória em findbugs

abaixo está o erro:

minha versão do sonar é 2,13

quando eu estou aumentando as opções de jvm no plugin de sonar Jenkins para 1280 é mostrado abaixo erro:

<code>Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit`enter code here`
