This fails using the latest version 1.8.21:

@PLUGINS_DIR: "plugins";

@import "@{BOOTSTRAP_DIR}/variables.less"; // fail
@import @{BOOTSTRAP_DIR}"/variables.less"; // fail as well

Edit, here is the server error:
File '/assets/css/@{BOOTSTRAP_DIR}/variables.less' not exist.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Hello, Erik!

In BundleTransformer.Less cannot use the string interpolation in file paths.

Use in the file paths only constants. This is limitations of the Bundle Transformer`s architecture.

Alright, thanks for the info, we can live without that part anyways.

Hello, Erik!

Now BundleTransformer.SassAndScss (see the Bundle Transformer 1.9.81 release notes) supports the string interpolation in file paths.

I'm confused. The original post refers to BundleTransformer.Less, but the update refers to BundleTransformer.SassAndScss. Does that mean it's still broken in BundleTransformer.Less? I updated to the latest BundleTransformer.Core and BundleTransformer.Less, and it's still not working. I just want to make sure I'm not doing something wrong.

Hello, ak47oh!

This problem is solved in the BundleTransformer.Less 1.9.92 and later versions.
