Hmpf, why did it smell like that? :)
But I can't see what the problem is.
I mean, it is no rocket science, it is pure copy/past science.
Add the deps to the pom:
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-swing</artifactId>
<version>${project.version}</version>
</dependency>
<dependency>
<groupId>org.geotools</groupId>
<artifactId>gt-shapefile</artifactId>
<version>${project.version}</version>
</dependency>
paste the following in a class as quickstart suggests:
---------------------------------------------
// display a data store file chooser dialog for shapefiles
File file = JFileDataStoreChooser.showOpenFile("shp", null);
if (file == null) {
return;
}
FileDataStore store = FileDataStoreFinder.getDataStore(file);
SimpleFeatureSource featureSource = store.getFeatureSource();
// Create a map content and add our shapefile to it
MapContent map = new MapContent();
map.setTitle("Quickstart");
Style style = SLD.createSimpleStyle(featureSource.getSchema());
Layer layer = new FeatureLayer(featureSource, style);
map.addLayer(layer);
// Now display the map
JMapFrame.showMap(map);
---------------------------------------------
If I run this, I get the exception. This is really annoing...
I also tried to run the class with mvn exec:java to see if it is eclipse.
I only can think of some jvm setting? No clue...
