digging into it, found that it uses ApacheNoticeResourceTransformer, that injects current year:

https://github.com/apache/maven-shade-plugin/blob/maven-shade-plugin-3.6.0/src/main/java/org/apache/maven/plugins/shade/resource/ApacheNoticeResourceTransformer.java#L91

**Affects:** 3.6.0

Start with src/main/java/org/apache/maven/plugins/shade/resource/ApacheNoticeResourceTransformer.java at the referenced line, and compare its generated META-INF/NOTICE output with the Paimon reproducibility diff. Determine how the notice year should behave without depending on the current year, then verify the result against a reproducible rebuild or an existing transformer test if one is found.
