The short code below can be compiled and run successfully, but *after
loading the shapefile*, shows error in line: FileDataStore store =
FileDataStoreFinder.getDataStore(file);
This is the way I compile and run it:
java -d . Quickstart.java
java org.geotools.tutorial.quickstart.Quickstart
Code:
package org.geotools.tutorial.quickstart;
import java.io.File;
import org.geotools.api.data.FileDataStore;
import org.geotools.api.data.FileDataStoreFinder;
import org.geotools.swing.data.JFileDataStoreChooser;
public class Quickstart {
public static void main(String[] args) throws Exception {
File file = JFileDataStoreChooser.showOpenFile("shp", null);
if (file == null) {
return;
}
FileDataStore store = FileDataStoreFinder.getDataStore(file);
}
}
The errors:

However, it can load the shapefile without problem when it's run by maven:
mvn exec:java -Dexec.mainClass=org.geotools.tutorial.quickstart.Quickstart
Any comment would be appreciated.
