java.lang.ClassNotFoundException: it.geosolutions.jaiext.range.Range

Question

Ich habe vor kurzem mein erstes Programm mit GeoTools gestartet, in dem ich auch JAI-Java Advanced Imaging verwendet habe. Ich fand folgende Fehler

Exception in thread "main" java.lang.NoClassDefFoundError: it/geosolutions/jaiext/range/Range at it.geosolutions.jaiext.crop.CropDescriptor.(CropDescriptor.java:62) at it.geosolutions.jaiext.crop.CropSpi.updateRegistry(CropSpi.java:56) at javax.media.jai.OperationRegistry.registerServices(OperationRegistry.java:2056) at javax.media.jai.ThreadSafeOperationRegistry.registerServices(ThreadSafeOperationRegistry.java:620) at javax.media.jai.OperationRegistry.initializeRegistry(OperationRegistry.java:373) at javax.media.jai.JAI.(JAI.java:566) at com.rgb.NDRI.createNDI(NDRI.java:17) at com.rgb.RGBSpliter.main(RGBSpliter.java:71) Caused by: java.lang.ClassNotFoundException: it.geosolutions.jaiext.range.Range at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 8 more

Die oben ist, was ich in der Konsole zu sehen. Ich weiß nicht aus allen Gläsern in Geotools 14.4, welches Glas fehlt.

Der Code ist wie unten

Answer 1

ich die fehlende Range-Klasse hier: https://github.com/geosolutions-it/jai-ext/tree/master/jt-utilities/src/main/java/it/geosolutions/jaiext/range

Also, versuchen Sie jt-Dienstprogramme und jt-Iteratoren zu einem Projekt hinzuzufügen.
