构建JFreeChart蚂蚁文件“build-fx.xml”

我想在我的程序中导入import org.jfree.chart.fx.ChartViewer;。经过一番研究，我发现我需要构建build-fx.xml文件，以便将该软件包包含在我的JFreeChart jar中。所以我在终端设置中使用了一行代码来构建ant ant -buildfile build-fx.xml，但是我在下面的输出中显示了一个错误。难道我做错了什么？构建JFreeChart蚂蚁文件“build-fx.xml”

C:\Users\dan\Desktop\jfreechart-1.0.19\ant>ant -buildfile build-fx.xml 
Buildfile: C:\Users\danie\Desktop\jfreechart-1.0.19\ant\build-fx.xml

对不起，如果这是显而易见的，这是我第一次不得不用蚂蚁建造一个罐子。

这是一个已知的错误，修复相当简单。请参阅here

要解决此问题，请在源文件中将protected String getUserAgentStylesheet() {更改为public String getUserAgentStylesheet() {，然后再次运行ant build。

这应该成功建立一个名为jfreechart-1.0.19-fx.jar的库到lib文件夹
