Arthas: illegal ENV, please set $JAVA_HOME to JDK6+

[lanshiqin]

OS Version: CentOS 7 64bit
JDK Version: 1.8.0_181
When I execute the command :

1. [root]# ./as.sh
   Arthas script version: 3.0.2
   Try out Arthas online: /arthas/web-console
   illegal ENV, please set $JAVA_HOME to JDK6+

1. [root]# echo $JAVA_HOME
   /usr/local/jdk1.8.0_181

I have configured the $JAVA_HOME environment variable in the .bash_profile file, and the input java-version is also output normally. When I execute ./as.sh, I am prompted to set the variable？

Hi, could you paste the debugging output of executing as.sh?

bash -x as.sh

I guess the reason is the JVM version /usr/local/jdk1.8.0_181 is not recognizable to Arthas.

It looks like your JAVA_HOME is not correctly configured.

Please run export JAVA_HOME=/usr/local/jdk1.8.0_181 before starting Arthas.

export VERY IMPORTANT

Thank You!
Because of a problem with my .bash_profile configuration
Old configuration：

JAVA_HOME=/usr/local/jdk1.8.0_181
PATH=$JAVA_HOME/bin:$PATH
export PATH

New configuration:

JAVA_HOME=/usr/local/jdk1.8.0_181
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
