如何将当前年份插入IntelliJ IDEA版权模板？

Question

我试图在IntelliJ IDEA版权设置中为MIT许可证制作Apache Velocity模板。我希望它打印年份的2015-${current_year}。以下是我尝试放入设置→版权→版权配置文件→MIT→版权文本：

#set ($current_year = $dateTool.getCurrentDate('yyyy'))
Copyright (c)  2015-${current_year}, My Name

但是，当我使用此模板在源文件中生成许可证标题时，它不打印当前年份编号，它只打印纯文本${current_year}。

如何让它打印当年？

Answer 1

This page of the documentation解释设置→版权→版权配置文件的内置Velocity变量：

Name    Type        Comment
$today  DateInfo    The current date and time.
...
DateInfo has the following properties:
year    int         The current year.

所以在我的情况下，我在模板中需要这个：

Copyright (c)  2015-${today.year}, My Name

Answer 2

正如here所述，${YEAR}是要走的路

Answer 3

#set($year = $today.year + 1900)

，可以称为${year}
