I wasn't able to get Java 8 to work within the JMonkey IDE. However I was able to do it the other way round; add JMonkey libraries to Netbeans 8.
<ul>
<li>Install <a href="https://netbeans.org/downloads/" rel="nofollow noreferrer">Netbeans 8</a></li>
</ul>
Then you follow the instructions <a href="http://hub.jmonkeyengine.org/wiki/doku.php/jme3:setting_up_jme3_in_eclipse" rel="nofollow noreferrer">for adding JMonkey as a library to annother IDE</a>. The instructions are for eclipse (as JMonkey IDE is based on Netbeans it would normally make no sense to do this).
<ul>
<li><a href="https://github.com/jMonkeyEngine/sdk/releases" rel="nofollow noreferrer">Download the most recent build of JMonkey</a>
</li>
<li>Unzip and save in your user directory
</li>
<li>Open Netbeans 8
</li>
<li>Either open an existing JMonkey project or Start a new project
</li>
<li>Open the project properties
<img src="https://i.stack.imgur.com/5FCn2.png" alt="enter image description here" />
</li>
<li>Select to add JARs
<img src="https://i.stack.imgur.com/ZaBIA.png" alt="enter image description here" />
</li>
<li>Browse to where you saved the JMonkey build and open the lib folder
<img src="https://i.stack.imgur.com/KgNwL.png" alt="enter image description here" />
</li>
<li>Select all the libraries and add them
<img src="https://i.stack.imgur.com/RmqWq.png" alt="enter image description here" />
</li>
</ul>
At this point it is now possible to create a JMonkey program using Java 8 code within Netbeans 8. However; the assets folder may still be missing,
If you opened an existing project it will likely be there otherwise, again, we follow similar instructions within <a href="http://hub.jmonkeyengine.org/wiki/doku.php/jme3:setting_up_jme3_in_eclipse" rel="nofollow noreferrer">Setting up JME3 in Eclipse</a> but its arguably easier in netbeans. Its pretty much identical to adding the JARs so I won't include screenshots.
<ul>
<li>Open the project properties (again)</li>
<li>Open the libraries tab</li>
<li>Click add JAR/Folder</li>
<li>Browse to assets folder</li>
<li>Click open</li>
</ul>
Now you can run your project just as within the JMonkey IDE, using <code>AssetManager</code> to load assets. Of course you won't have all the nice JME specific features of JMonkey IDE.
Note; <a href="http://hub.jmonkeyengine.org/forum/topic/include-last-updated-date-on-the-download-page/#post-265058" rel="nofollow noreferrer">JMonkey is untested with Java 8</a>, I got a basic program to run, this does not guarantee success with a more complex program (That said I have now used this technique to move my 500 class game across with zero issues; I love java)

I want to use lambda expressions, so i need JDK 8. I have set the project to JDK 8, in properties, but editor of the code gives errors when i use lambda. When trying to build it gives error like this:
<code>warning: [options] bootstrap class path not set in conjunction with -source 1.7
Test.java:17: error: lambda expressions are not supported in -source 1.7
 Runnable r = () -&gt; System.out.println();
 (use -source 8 or higher to enable lambda expressions)</code>
 So how to set JMonkeyEngine working on JDK 8?
Thanks.

我想要使用lambda表达式，所以我需要JDK 8。我已经在属性中将项目设置为JDK 8，但是代码编辑器在使用lambda时会出现错误。当尝试构建时，会出现如下错误：warning: [options] bootstrap class path not set in conjunction with -source 1.7 Test.java:17: error: lambda expressio
