如何在Mac OS El Capitan的终端上添加永久的CLASSPATH？

Question

I want to add the java-servlet-api.jar to the classpath variable.

export CLASSPATH=/.../java-servlet-api.jar

adds the class path to only one session of the terminal. How do I permanently add this to CLASSPATH?

I looked at a few links which asked me to modify the bashrc file, but I am unable to locate it on EL Capitan. Can someone help me with this?

Answer 1

You choose 1 of 2 solutions below:

Solution 1 : Open Terminal, then type:

export CLASSPATH=$CLASSPATH:/path/to/file/java-servlet-api.jar

then:

source .bash_profile

Solution 2 : Open terminal, type command:

vim ~/.bash_profile

you will see something like this:

press i , add your file to classpath like sample.

then, press esc , type :wq , then return

Make effective: don't need restart, type:

source .bash_profile

Answer 2

By default, I am not sure that Mac OS terminal launches the .bashrc file. But it launches the .profile for sure.

Open a new terminal and launch this command :

echo 'export CLASSPATH=/.../java-servlet-api.jar' >> $HOME/.profile

Then open a new terminal and your environment variable should be ok.
