jasper-reports之org.eclipse.swt.SWTException 尝试使用按钮将报告发布到 JasperReports Server

我正在尝试使用 Jaspersoft Studio 中的按钮将报告发布到 JasperReports Server，但对话框打不开。

这是我在 .metadata/.log 文件中看到的错误

我正在使用 Linux 4.7.2-1-ARCH 和 Jasper Studio:6.3.0。

请您参考如下方法:

似乎连接到新的 GTK 3。

打开对应的studio ini文件，添加参数

--launcher.GTK_version 2 

就在

-vm ......
