关于java使用geotools中的GeoTiffReader读取tif图像时报错：找不到类 javax.media.jai.PlanarImage 的错误
代码放上：

import java.io.File;
import org.geotools.coverage.grid.GridCoverage2D;
import org.geotools.gce.geotiff.GeoTiffReader;
import org.geotools.geometry.Envelope2D;
import org.opengis.referencing.crs.CoordinateReferenceSystem;

public class ImageExt {
    public static void main(String[] args) {
        GetImageExt("E:\\database\\overview\\\\J46\\J46D001001.tif");
    }
    public static String GetImageExt(String strImageUrl){
        String strExtent = "";
        try {
            String ImageUrl=strImageUrl.replace("\\", "\\\\");;
            File ImageFile=new File(ImageUrl);
            GeoTiffReader reader=new GeoTiffReader(ImageFile);
            GridCoverage2D coverage = reader.read(null);
            CoordinateReferenceSystem crs = coverage.getCoordinateReferenceSystem2D();
            Envelope2D coverageEnvelope = coverage.getEnvelope2D();
            double coverageMinX = coverageEnvelope.getBounds().getMinX();
            double coverageMaxX = coverageEnvelope.getBounds().getMaxX();
            double coverageMinY = coverageEnvelope.getBounds().getMinY();
            double coverageMaxY = coverageEnvelope.getBounds().getMaxY();
            
        } catch (Exception e) {
            // TODO: handle exception
        }
        System.out.println(coverageMinX);    
        return strExtent;
        
    }

}

报错：

Exception in thread "main" java.lang.NoClassDefFoundError:

zy3dms.ImageExt.GetImageExt(ImageExt.java:18) at
zy3dms.ImageExt.main(ImageExt.java:11) Caused by:

我不解的是两个工程同样的类，一个运行正常，一个报错。
