ResourceNotFoundException when using custom Mustache templates in Linux

[thomasschoeftner]

It seems that sbt-pack (or the contained Scalate invocation) cannot find custom script template (Mustache) file Linux. The URI works on windows, but I get a ResourceNotFoundException when running in Linux. Other Linux tools can successfully resolve the URI, though. - It seems structurally correct.

Acc. to the stack trace Scalate's doesn't find the resource. Maybe it has something to do with the way that Scalate is invoked?

Stack trace:

Edit: I have tried with pack 0.4.3 and 0.5.2-SNAPSHOT. - The same error occurred with both version.

The stack trace actually originates from a custom built version where I've tried this: https://groups.google.com/forum/#!topic/scalate/q6HC-9n1WW0 ... it didn't help!

This part simply invoking Scalate. https://github.com/xerial/sbt-pack/blob/develop/src/main/scala/xerial/sbt/Pack.scala#L223

And Scalate engine is created in a normal way: https://github.com/xerial/sbt-pack/blob/develop/src/main/scala/xerial/sbt/Pack.scala#L223

I guess it's a classloder issue if the resource can be found in a classpath.

[thomasschoeftner]

Nope, it's not a classloader issue. It seems that scalate has problems resolving mustache files which are outside the folder where sbt or the application is executed.

Example: My project is in repo/sources/project/. The mustache files, however, are outside in repo/templates/xy.mustache Specifying a relative path (in the sbt-pack settings) to the mustache files outside the sbt project always leads to that problem.

I looked at the scalate code and it essentially loads any URL... It's definitely a problem with Scalate...

using a canonical file to load the Template - rather than loading the template by URI - seems to work... I'll test it out and send a pull request if it works

[xerial]

Thanks. So copying the script resource to some tempolary file, then let Scalate load it. 2014/04/04 19:51 "thomasschoeftner" [email protected]:

Pull request created - it contains a fix. The templates are specified via paths (not URLs) relative to the root project... Let me know what you think...
