Error when trying to load rules_twirl.

[Srikrishna31]

Thanks for writing a wrapper for twirl template compiler. I'm trying to use it in my project, and with the changes as suggested in the readme.md, I see the following error:

Am I missing something? I see the same error in Linux as well.

Thanks,

Hi Krishna,

Are you invoking twirl_repositories() from your WORKSPACE after loading it?

Could you please share a minimal reproducible example so we can help you troubleshoot more effectively? Also, which version of Bazel are you using?

Thanks,
Sergio

[Srikrishna31]

Hello Sergio,
Thank you for your response. My repository is open in github. Here is the link to the PR: Srikrishna31/scala_play#9 - If you look in the workspace file, I commented out the rules_twirl part, since that was creating issues for me. I'm using bazel version 3.1.0.

Let me know if the project link I provided is sufficient, or you still want a more minimal example.

Thanks,
Krishna

Hey Krishna,

It looks like you're using a rather old version of rules_twirl; updating to the latest version fixes the issue. Could you please try updating to the latest version?

rules_twirl_version = "9ac789845e3a481fe520af57bd47a4261edb684f"
sha256 = "b1698a2a59b76dc9df233314c2a1ca8cee4a0477665cff5eafd36f92057b2044"

I'll update the readme to stop recommending such an old commit.

Please let me know if you run into other issues.

-Sergio

@Srikrishna31 I'm closing this issue since updating the version should do the trick; please let me know if you run into any other issues :)

[Srikrishna31]

Hi Sergio, Thanks for the reply. Let me try with the latest version. Thanks, Krishna

Hi Sergio, The new version poses a new problem. Below is the output that I see with the new version:

My index.scala.html and main.scala.html are very simple files. main.scala.html doesn't take any parameters, and that might be causing a NullPointerException?
It's the same PR: Srikrishna31/scala_play#9
