我是javaFX的新手。我在javaFX中创建了应用程序，它在项目内部有maven，当我运行项目时，它完美地工作。但是在制作了罐子之后，我无法在点击打印按钮后将其打印出来，这会让我出现以下错误。

添加到您的pom.xml jasper依赖项：

<project>
**********************************
<properties>
    <jasperReport.version>yourversion</jasperReport.version>
</properties>
<dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>${jasperReport.version}</version>
</dependency>
**********************************
</project>

然后使用命令行转到项目的根文件夹，然后运行此命令：

mvn clean install

您也可以使用以下代码进行构建。

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                <executions>

                        <id>copy-dependencies</id>
                        <phase>prepare-package</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
