Yes. Although the EPL and GPL are usually incompatible, we added an exception that allows you to use and distribute an unmodified, binary version of IGE under the terms of the GPL v2 or later. However, if you do this, you also have to make both the binary and source code available under the same license as IGE.
Our license allows you to reuse our code only if you distribute your code under the same license. If you'd like to reuse our code in a project that's not related to IGE, you can however ignore our GPL exception and distribute your code under the normal EPL.
