java - Ubuntu Maven environment variable setting trouble -


i trying set environment variables jdk & maven in ubuntu .profile file . relevant lines :

if [ -d /etc/profile.d ];   in /etc/profile.d/*.sh;     if [ -r $i ];       . $i     fi  m2_home=/usr/local/maven/apache-maven-3.3.3 m2=$m2_home/bin maven_opts="maven_opts=-xms256m -xmx512m" catalina_home=/usr/local/tomcat/apache-tomcat-8.0.23 java_home=/usr/local/java/jdk1.7.0_80 jre_home=$java_home/jre path=$m2:$path:$jre_home/bin:$java_home/bin:/bin  export java_home export jre_home export m2_home export m2 export maven_opts export path done   unset fi

when , unable run maven , , have edit out maven variables & export them separately on terminal window.

what can maven installation working , while keeping above mentioned variables in .profile file ?

why not use package manager? 

sudo apt-get install maven
