truthy 不适用于 sbt new
truthy doesn't work with sbt new
我用giter8创建了一个模板项目，并尝试添加条件表达式。
在defaults.properties我补充说：
param=true
并在我添加的模板文件中：
$if(param.truthy)$
....
$endif$
当我生成项目时：
g8 file://proj.g8
一切如预期。
在交互部分，param 将有 2 个选项：
param [YES/no]:
并且生成的文件将包含基于 param
值的附加文本
但是，当我生成项目时：
sbt new file://proj.g8
param 被视为字符串。
在交互部分，没有 yes/no 选项：
param [yes]:
我收到以下错误：

我正在为 g8 和 sbt-giter8 插件使用版本 0.11.0-M3
我该如何解决这个问题？
编辑：更多细节：
我正在使用 sbt 1.1.1（用于我机器上的 g8 项目和 sbt 启动器）
我在文件 project/plugins.sbt 和
的 g8 项目中添加了插件
addSbtPlugin("org.foundweekends.giter8" %% "sbt-giter8" % "0.11.0-M3")
如果我从模板中删除真实的部分，项目就会从 sbt new
中正确生成
此问题已在 sbt 1.2.0 中修复
为了修复，应该使用：
sbt -Dsbt.version=1.2.0 new file://proj.g8
sbt new 内部使用的 giter8 版本是固定的，添加 sbt-giter8 插件不会改变它。 sbt 1.1.1 uses sbt-giter8-resolver v0.1.3, which uses giter8 0.7.2（不支持条件）。
你可以更新 sbt-giter8-resolver，在本地发布并尝试替换默认的 Giter8TemplatePlugin，但我认为这不值得。直接使用 g8 直到 sbt 更新。
有 was an effort to support arbitrary giter8 version set in the template, but something went wrong，此功能已恢复。
我用giter8创建了一个模板项目，并尝试添加条件表达式。
在defaults.properties我补充说：
param=true
并在我添加的模板文件中：
$if(param.truthy)$
....
$endif$
当我生成项目时：
g8 file://proj.g8

并且生成的文件将包含基于 param
