diffplug
A required class was missing while executing com.diffplug.spotless:spotless-maven-plugin:2.4.2:check: com/sun/source/tree/Tree
-A required class is missing even though I added the jar scorcerer-javac in the dependencies section of the plugin as well.
- Maven version 3.6.0
- spotless version 2.4.2
- Operating system
Description: Ubuntu 20.04.2 LTS - JDK version 11.0.11
- I am using Flink's github repo https://github.com/apache/flink to run projects under flink-examples and flink-examples-batch project, I created an effective pom.xml for Flink-Examples and also tried to comment out spotless-maven-plugin but i suspect it's being called from Flink force shading plugin.
