通过Ant-style风格路径生成graalVM的reflection-config.config文件

如下

import org.springframework.util.AntPathMatcher;import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;/*** generate reflection-config.json for native-image* @author cjbi*/

}
