我的GMapsFX库文件出错 [英] Have an error with my GMapsFX library files

问题描述

我正在尝试将GMapsFX库链接到FXML文件，但是在尝试打开实际的地图页面时，此错误始终出现.

I'm trying to link a GMapsFX library to an FXML file but this error keeps appearing when trying to open the actual map page.

FXML文件:

<?xml version="1.0" encoding="UTF-8"?>

<?import com.lynden.gmapsfx.GoogleMapView?>
<?import javafx.scene.layout.AnchorPane?>


<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" 
minWidth="-Infinity" prefHeight="602.0" prefWidth="540.0" 
xmlns="http://javafx.com/javafx/9.0.1" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <GoogleMapView layoutY="1.0" prefHeight="602.0" prefWidth="540.0" />
   </children>
</AnchorPane>

我已经下载了正确的JAR文件，但我认为可能是错误的.

I have already downloaded the correct JAR files but I feel it may be an error with that.

这是错误:

推荐答案

阅读消息:

java.lang.ClassNotFoundException:org.slf4j.LoggerFactory

java.lang.ClassNotFoundException: org.slf4j.LoggerFactory

您需要将slf4j-.jar添加到您的类路径中:

You need to add slf4j-.jar to your classpath:

https://www.slf4j.org/download.html

对于新项目，我强烈建议使用依赖管理工具，例如 maven 或

For new projects I sugeest to use an dependency management tool like maven or gradle. It makes the handling of dependencies much more easier.
