Sencha Cmd installation on Mac: Java not found

Question

Trying to install Sencha Command 3.1.1 on my iMac (10.8.3). The installer is saying:

The installer could not find a valid Java(tm) on this machine.
Supported versions: Vendor : Any  min. 1.6.0 max. any

Following another Stack Overflow thread, I tried linking /usr/bin/java to /Library/Internet Plugins/JavaAppletPlugin.plugin/Contents/Home/bin/java. Now, I get this on the command line:

~ 🍔  java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

So that looks good, but the installer still complains that it cannot find Java. Why can't it?

Answer 1

What eventually fixed this for me, after consulting with Sencha support, was installing the full JDK rather than just the JRE. I don't know exactly why this fixed it, or what the root cause was, but now Command installed successfully and is working fine.
