JavaFX Maven插件：没有找到前缀＆＃39; jfx＆＃39;的插件在当前项目和插件组中

Question

我试图在Eclipse Maven项目中为我的JavaFX应用程序创建一个可执行jar。

我跟随这个帖子： JavaFx Application with Maven in Eclipse

这个turotial： https://www.youtube.com/watch?v=wbjW8rYlook

我在尝试运行目标时遇到了No plugin found for prefix 'jfx' in the current project and in the plugin groups因错误：jfx:jar

完整版本错误：

我已尝试以下方法试图解决此问题：
1.输入mvn clean install（BUILD SUCCESS）
2.在settings.xml上添加了<pluginGroup>com.zenjava</pluginGroup>

另外，我已经在我的pom.xml中添加了<plugin>节点

    <plugin>
        <groupId>com.zenjava</groupId>
        <artifactId>javafx-maven-plugin</artifactId>
        <version>8.1.2</version>
        <configuration>
            <mainClass>com.sample.MainApp</mainClass>
        </configuration>
    </plugin>

我该如何解决这个问题？

=============================================== ============
更新1：
在听完Jaydeep的回答后，我在尝试打开cacerts文件后无法继续进行密码提示。

=============================================== ============
更新2：
cacerts的默认密码是＆＃34; changeit＆＃34;。 导入根证书后，构建成功。 此外，我已根据FibreFoX的建议，使用jfx插件版本8.7.0更新了我的pom文件。

Answer 1

您需要将网络ssl证书安装到jre cacerts。

第1步：获取证书。

1. 使用Chrome浏览器打开https://repo.maven.apache.org网址。
2. 点击查看证书
3. 选择链上最顶级的证书并拖放到桌面。

第2步：将证书安装到cacerts

1. 打开命令提示符或终端并键入命令

  

mvn -version

1. 抓住jre的路径，在输入上面的命令后会显示给你。
2. 下载this工具。
3. 在该工具中选择打开选项，然后导航到您在第2点抓取的路径。现在您处于jre文件夹中。打开lib文件夹。打开安全文件夹。（YOURMAVENJDKPATH / jre / lib / security / cacerts）
4. 选择位于该安全文件夹中的cacerts文件。现在您可以看到该工具中的所有证书。 工具会要求输入密码＆＃34; changeit＆＃34;（没有双引号字符串changeit是密码）
5. 找到导入证书图标并单击它。
6. 选择您在步骤1中下载的证书。
7. 保存更改并关闭工具。

现在你的问题已经解决了。
