无法在LibreOffice Extension Java Eclipse项目

Question

我刚开始开发桌面应用程序，可以使用libreoffice扩展程序与linux的libreoffice进行通信。

我正在尝试Github LibreOffice Extension Code Sample。 它显示错误“编辑器无法初始化”并记录在下面。

java.lang.NullPointerException

它还在项目文件夹上显示了一些U字母，在下面的types.rdb文件中显示了D字母的蓝色。这是什么意思？

在运行此项目时，它显示错误“未处理的事件循环异常”和下面的错误日志。

我尝试使用File-＆gt; New-＆gt; Project-＆gt; OpenOffice-＆gt; Extension Project创建一些示例项目。仍然在下面得到同样的错误。

此外，我尝试了this和this，但仍未获得正面结果。

任何帮助都会非常感激。

错误是由于项目作为LibreOffice Extension运行。

为了解决这个问题，我创建了一个名为LibreOffice Application（而不是扩展名）的新配置。它现在运行顺利。
