Пытаюсь собрать проект, на определенном этапе выводит:

Как я понял, ошибка в нехватке PermGen space.
Выставлял параметры такой командой: export JVM_ARGS="-Xmx1024m -XX:MaxPermSize=256m"
MaxPermSize выставлял и 512m и 1024m.
Может ошибка не в этом? Или я неправильно выставляю параметры?

Вообще у мейвена своя переменная окружения - MAVEN_OPTS. Попробуйте выставить ее. Но вообще это мягко говоря странно, что при сборке проекта вылезает OOM PermGen. Что собираете, если не секрет ?

Собираю MAP шлюз https://github.com/RestComm/jss7/
Команда export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=256m" помогла, спасибо!
