如何在Cloude 9（c9）IDE中设置PATH环境变量和/或运行需要Java的npm模块

Question

For various reasons (and because of a recent back injury), I needed to get an "ultra-light" laptop. I went with the recently best-selling Samsung Chromebook , and I can actually get quite a lot of real work done.

I ported one of my projects (very alpha) over to Cloud9 , the service of which is outstanding (really, really good). Because c9 is effectively running NodeJs on NodeJs for each workspace you define: I can run all of my Node tasks; I can Grunt in c9; nearly anything I can do on a "full" OS, I can do in c9.

Except for Java dependent tasks. Specifically with Grunt, there are a few tasks I can't run because no environment variable for Java can be found:

JAVA_HOME is no set, but java is required by jsdoc to run.

Never-minding the grammar, it is possible to run jsdoc (or closure-compiler, etc) by opening c9's proper Terminal which:

somecallmechief@ojs:~/406658 (master) $ which java                                                                                                                                                            
    /usr/bin/java                                                                                                                                                                                                 

knows all about Java. I can even export the path and run my Grunt tasks in the terminal--but only in this Terminal instance.

Given that Java is clearly part of my virtual workspace, is it possible to define the JAVA_HOME environment variable as a constant/persistent value? And if so, how?

Thanks for listening

• and no, npm install java is not the answer

Answer 1

It looks like Cloud9 is tackling this themselves. Based on their latest blog post , the former 'Console' is no more. Instead you get the Terminal right out of the box, and since it's a fully baked, fully configurable bash terminal--that's all you need.
