Envilonment

• Windows 7
• sbt version: 1.1.0

Repoducing procedures is as follows:

• sbt new foundweekends/giter8.g8
• use all default value
• cd my-template-project
• sbt g8Test (Works fine)
• change src/main/scala/stub.scala to src/main/scala/$name$.scala
• Then, execute again "sbt 8Test", but it failed with following messaages.

However, it works fine to use this template as follows

sbt new file://./my-template-project/

Same issue with version "0.13.0-M1" and sbt version: 1.3.8.

org.stringtemplate.v4.compiler.STException: relative: **\$classname$.scala, toPath: **\sbt-test\**\scripted, An unexpected

[TonioGela]

It's not happening to me, the second time I prompt sbt g8Test the tests are not failing
@melito00 @tonykoval can you confirm if is still happening?
Env:

MacOsX 10.15.7
sbt 1.5.2 
java AdoptOpenJDK Java 1.8.0_292

[melito00]

I still have same issue with following environment.

name [My Template Project]:
giter8_version [0.13.1]:
sbt_version [1.5.5]:
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_292-b10)

Hi,

I think I've hit this same issue, and after way too much tinkering I could not find for sure what the issue is, but I have a few ideas.

In my case the full error log is

sbt:scala.g8> g8Test

First, it seems the issue is specific to Windows as, like the OP, I'm on Windows.

Second, it seems the issue occurs when running g8Test, but now when using the template via sbt new. At least that's what I'm seeing here.

I stumbled upon #334 which mentions that g8Test does not go through the same code path as running sbt new, one calling G8.apply and the other calling G8.applyT

Indeed it would seem that G8.expandPath is called with somewhat different arguments depending on the caller being apply or applyT (via G8.writeTemplates). In the second case, the argument goes through G8.relativize, which by calling .toURI, will replace \ with / in the relative path (this is where Windows is relevant).

Now I would have expected the call to expandPath from applyT (which goes through relativize) to be the one to fail, given that expandPath was apparently recently fixed to handle Windows file separators, but it seems to be the opposite and at this point I'm utterly confused. Nevertheless, maybe this info can help someone better equipped than me to look at this in more detail?

Thanks in advance
