  • Creating support scripts for Java environment

In this section, support scripts are created in order to configure and reconfigure the Java environment in the machine quickly and easily.

1-      Create the directory and files to fill

cd ~
mkdir bin
cd bin
touch setenv7.0.80_BASE
touch setenv7.0.80_FULL
chmod ugo+x setenv7.0.80_BASE
chmod ugo+x setenv7.0.80_FULL 

2-      Fill in the scripts with their respective contents

Contens of ~/bin/setenv7.0.80_BASE 

 
#!/bin/bash

  1. -----------------------------------------
  2. NOTE: To be invoked as "source ..."
  3. -----------------------------------------
    export JAVA_HOME=/usr/local/jdk1.7.0_80
    export PATH=$JAVA_HOME/bin:$PATH
    clear
    echo JAVA_HOME[${JAVA_HOME}]
    echo PATH[${PATH}]
    java -version 

Contents of ~/bin/setenv7.0.80_FULL 


#!/bin/bash

  1. -----------------------------------------------------------------
  2. NOTA: para ser invocado como "source ..."
  3. -----------------------------------------------------------------
    export JAVA_HOME=/usr/local/jdk1.7.0_80
    export ANT_HOME=/usr/local/apache-ant-1.9.9
    export M2_HOME=/usr/local/apache-maven-3.3.9
    export GROOVY_HOME=/usr/local/groovy-2.4.9
    export M2=$M2_HOME/bin
    export MAVEN_OPTS="-Xms256m -Xmx512m -Dmaven.artifact.threads=3"
    export PATH=$JAVA_HOME/bin:$M2:$ANT_HOME/bin:$GROOVY_HOME/bin:$PATH
    clear
    echo JAVA_HOME[${JAVA_HOME}]
    echo PATH[${PATH}]
    java -version
    ant -version
    mvn --version
    groovy –version  

3-      Add alias for scripts to: .bashrc
