Bnd Template: Failed to compile template '_mapping': _mapping 2:24: doesn't look like an expression #1356

Open mikerumpf opened 1 month ago

In Eclipse 4.31 https://eclipse.dev/eclipse/news/4.31/pde.php#bndtemplates was introduced (thanks a lot!). However I can't get it to work. Whenever I create a plugin from the example template I get the following exception.

`java.lang.IllegalArgumentException: Failed to compile template '_mapping': _mapping 2:24: doesn't look like an expression

@mikerumpf can you share what exactly is chosen in the wizard (maybe even a screencast)? Is it the same for String Template and Mustace Template?

bndtemplate

Mustache Template works fine btw.
