无法实例协调资源系统java.lang.NoClassDefFoundError：org.geotools.factory.Hints

Question

我试图使用Geotools Java库在我的一个项目，我就用摇篮和14.3版本内置：

compile 'org.geotools:gt-shapefile:14.3' 
compile 'org.geotools:gt-epsg-hsql:14.3' 

基本上，任何时候我尝试实例化一个CoordinateResourceSystem，如：

java.lang.NoClassDefFoundError: org.geotools.factory.Hints 
at org.geotools.referencing.CRS.<clinit>(CRS.java:181) 

：

CoordinateReferenceSystem crs; 
try { 
    crs = CRS.decode("epsg:4326"); //also tried DefaultGeographicCRS.WGS84_3D 
} catch (FactoryException e) { 
    e.printStackTrace(); 
} 

我在运行时出现此错误

我到目前为止收到的所有建议都与启用Multidex有关，我尝试过每一个Gradle组合，但无济于事。还尝试清洁和建设几十次。无论我做什么，我都会在运行时收到这个讨厌的错误。任何想法，为什么这可能是？我可以在罐子里看到课堂。

我注意到，这个依赖项导入了几个罐子，所有罐子都有相似的包名。这些软件包名称是否会造成一些混淆？

真的很茫然，我不能继续我的项目，直到我想出了如何正确实现这些代码。

编辑

这里是我的logcat的。表明ART处理某些geotools类（包括culrpit提示类）似乎存在某种问题。

Answer 1

打破GeoTools引用的“常用方法”是不包含EPSG工厂或包含多个工厂。从你的问题，我不知道你的问题是哪个。如FAQ中所述，您需要使用epsg罐之一，通常是gt-epsg-hsql。

你的问题被标记为Android，并且有some known issues与GeoTools使用的基于SPI的工厂查找系统，但我不认为这应该是这个问题。
