Frequent plugin errors when working on apple/pkl

[odenix]

When working on Java/Kotlin code of the apple/pkl project, I regularly get exceptions from the Pkl plugin.
Sometimes the exception prevents me from using a Java/Kotlin IDE feature such as "find method usages".

Here is an exception I get frequently:

Error during processing of: 0.26.adoc

java.util.NoSuchElementException: Key base is missing in the map.
