+The jMonkeyEngine's default IDE (xref:sdk/what_s_an_ide.adoc[Integrated Development Environment]) bases on the link:http://platform.netbeans.org[NetBeans RCP (Rich Client Platform)]. There is a RCP for Eclipse too, so why don't we use Eclipse as IDE for jMonkey? Well, there's several reasons:
 
 .  Eclipse uses a proprietary +++<abbr title="Graphical User Interface">GUI</abbr>+++ system (SWT), NetBeans uses the Java-default AWT implementation for which a high-performance canvas display exists in LWJGL/jME3. AWT compatibility allowed e.g. integration of plugins like NeoTexture.
 .  Eclipse projects are proprietary and they can not be opened without Eclipse. The NetBeans Platform uses the ANT standard which works outside the IDE as well, and can be extended by other build processes that use ANT (e.g. Android deployment). Furthermore, Eclipse can open projects generated by the NetBeans-based jMonkeyEngine SDK if needed.
