And when using this plugin in a maven project, the same error is generated:

The cause seems kaitai-io/kaitai_struct#822, but I don't know how to fix it as the kaitai struct compiler isn't installed but just downloaded and executed from a cache directory. So, I can't really set the KAITAI_STRUCT_COMPILER_HOME.

As #59 shows, the project builds correctly on both Windows and Linux.
You need to check if the environment on your computer is correct.
