Java Jasper报告编译错误

当我试图使用Jasper报告编译Java代码时，遇到了一个问题

我遵循了本教程：

这是我的密码：

public static void main(String[] args) throws SQLException, ClassNotFoundException {
    Class.forName("com.mysql.jdbc.Driver");
    Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/jasper", "root", "root");

    JasperReportBuilder report = DynamicReports.report();// a new report

    report.columns(Columns.column("Customer Id", "id", DataTypes.integerType()),
            Columns.column("First Name", "first_name", DataTypes.stringType()),
            Columns.column("Last Name", "last_name", DataTypes.stringType()),
            Columns.column("Date", "date", DataTypes.dateType()))
            .title(// title of the report
                    Components.text("SimpleReportExample").setHorizontalAlignment(HorizontalAlignment.CENTER))
            .pageFooter(Components.pageXofY())// show page number on the
                                                // page footer
            .setDataSource("SELECT id, first_name, last_name, date FROM customers", connection);

}

这是我的pom.xml依赖项：

<dependencies>
        <!-- DynamicReports -->
    <dependency>
        <groupId>net.sourceforge.dynamicreports</groupId>
        <artifactId>dynamicreports-core</artifactId>
        <version>3.1.3</version>
    </dependency>

        <!-- MySQL database driver -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.25</version>
    </dependency>
</dependencies>

是的，我使用EclipseNeonlooks就像你的Eclipse有问题一样。在SO上有很多帖子在Eclipse上也有类似的问题。顺便说一句，你在课堂上有导入吗？是的，Alex，我尝试在pom.xml中使用以下依赖项：net.sf.jasperreports jasperreports 3.7.5，我无法导入classI，我将尝试看看这是否是eclipse问题。谢谢，我使用EclipseNeonlooks就像你的Eclipse有问题一样。在SO上有很多帖子在Eclipse上也有类似的问题。顺便说一句，你在课堂上有导入吗？是的，Alex，我尝试在pom.xml中使用以下依赖项：net.sf.jasperreports jasperreports 3.7.5，我无法导入classI，我将尝试看看这是否是eclipse问题。谢谢
