在Eclipse Luna版本（4.4.0）中安装Maven时出错

Question

我正在尝试在Eclipse版本Luna Release（4.4.0）上安装Maven并最终出现错误

  Harney_Transects <- readOGR(dsn = ".", layer = "Transect_HN")

  MeanTreeHeightHarneyBefore=raster('HN_TrMean_B_Clip.tif')
  ScanAngleHarneyBefore= raster('HNScanAngle_B_Clip.tif')
  MeanShrubHeightHarneyBefore= raster('HN_MeanShrub_B_Clip.tif')

  Extraction_Shrub_Harney= extract(MeanShrubHeightHarneyBefore,Harney_Transects)
  Extraction_Tree_Harney= extract(MeanTreeHeightHarneyBefore,Harney_Transects)
  Extraction_ScanAngle_Harney= extract(ScanAngleHarneyBefore,Harney_Transects)

我尝试使用Maven位置：http://download.eclipse.org/technology/m2e/releases

也在MarketSpace上尝试过

可能是我的问题很基本，但是却破坏了我的生活。 ：（

为此寻求帮助。:)

谢谢
