I use https://github.com/libgdx/box2dlights in my game, But its not working, I get the following error in eclipse
Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.NoSuchMethodError: com.badlogic.gdx.graphics.glutils.FrameBuffer.getColorBufferTexture()Lcom/badlogic/gdx/graphics/GLTexture; at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:120) Caused by: java.lang.NoSuchMethodError: com.badlogic.gdx.graphics.glutils.FrameBuffer.getColorBufferTexture()Lcom/badlogic/gdx/graphics/GLTexture; at box2dLight.LightMap.render(LightMap.java:41) at box2dLight.RayHandler.render(RayHandler.java:338) at box2dLight.RayHandler.updateAndRender(RayHandler.java:269) at com.mygdx.game.box2dTest.render(box2dTest.java:182) at com.badlogic.gdx.Game.render(Game.java:46) at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop(LwjglApplication.java:207) at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:114)

I believe you have an old version of libGDX. Change gdxVersion field to gdxVersion = "1.7.0"in build.gradle in the root folder of your project.
