In Dreamweaver 2014, the prompt does not appear when you launch Dreamweaver. However, you are prompted to install Java SE 6 runtime while logging in to PhoneGap Build service (Site > PhoneGap Build Service > PhoneGap Build Service).
In the pop-up window that appears, click Install and follow the onscreen instructions to install Java SE 6 Runtime.

In Dreamweaver 2014, you can't log in to PhoneGap Build service without installing Java SE 6 Runtime.
Important: Ensure that you install Java SE 6 Runtime only by clicking Install in the pop-up window. If you install Java SE 6 or 7 Runtime through any other means (for example, by directly accessing Java.com), Dreamweaver could still display the prompt.
Even if you have installed Java SE 7 Runtime, you still need to install Java SE 6 Runtime as described above.
