问题:

I downloaded the eclipse Javascript IDE from the official download page however, when i start the application it says "A Java Runtime Environment or Java development Kit must be available in order to run eclipse." I already have a java IDE copy of eclipse that runs fine so I don't understand why its asking for another JDK.

I just want to develop Javascript in Eclipse, does anyone have any idea how to? Are there special tools or plugins i'm meant to get to get it to work?

回答1:

For best experience doing JS/HTML/CSS I recommend you using Aptana as plugin. Here you can download it http://www.aptana.com/products/studio3/download Be sure to check Eclipse Plug-in Version option.

Maybe other copy of eclipse use -vm variable in eclipse.ini file, therefore, it work correctly. Make sure you have JAVA_HOME in Environment Variables or add -vm configuration into eclipse.ini file.

Check your version of the runtime that you installed. You can upgrade or downgrade (i.e. if JDK 7, then try JDK 8 and vice versa you can even try JDK 6) and see if it works.

On Ubuntu 14.10 open JDK 7 did not help me much but the older (open JDK java 6 runtime) and the newer open JDK Java 8 helped me out.
