Por motivos de segurança, sudo
pode limpar as variáveis de ambiente e é por isso que provavelmente ele não está pegando $ JAVA_HOME. Procure no seu arquivo /etc/sudoers
para env_reset
.
De man sudoers
:
env_reset If set, sudo will reset the environment to only contain the following variables: HOME, LOGNAME, PATH, SHELL, TERM, and USER (in addi- tion to the SUDO_* variables). Of these, only TERM is copied unaltered from the old environment. The other variables are set to default values (possibly modified by the value of the set_logname option). If sudo was compiled with the SECURE_PATH option, its value will be used for the PATH environment variable. Other variables may be preserved with the env_keep option. env_keep Environment variables to be preserved in the user's environment when the env_reset option is in effect. This allows fine-grained con- trol over the environment sudo-spawned processes will receive. The argument may be a double-quoted, space-separated list or a single value without double-quotes. The list can be replaced, added to, deleted from, or disabled by using the =, +=, -=, and ! operators respectively. This list has no default members.
Então, se você quiser manter JAVA_HOME, adicione-o a env_keep:
Defaults env_keep += "JAVA_HOME"
Como alternativa , defina JAVA_HOME
em ~/.bash_profile
da raiz.
