pre-requisites

steps

The main branch demonstrates how things worked with Spotless 5.1.0

• Run git checkout -f main
• Run git checkout HEAD~1 followed by ./gradlew spotlessApply: Run git diff to see that Spotless has added the copyright header to HelloWorld.java correctly substituting the current year for $YEAR
• Run git checkout -f main followed by ./gradlew spotlessApply: Run git diff to see that Spotless has fixed the copyright header in HelloWorld.java making no other changes besides eliminating the extra space before "All Rights Reserved"

The test/5.4.0 branch demonstrates how things continue to work with Spotless 5.4.0

• Run git checkout -f test/5.4.0
• Run git checkout HEAD~1 followed by ./gradlew spotlessApply: Run git diff to see that Spotless has added the copyright header to HelloWorld.java correctly substituting the current year for $YEAR
• Run git checkout -f test/5.4.0 followed by ./gradlew spotlessApply: Run git diff to see that Spotless has fixed the copyright header in HelloWorld.java making no other changes besides eliminating the extra space before "All Rights Reserved"

The test/5.5.0 branch demonstrates how things have changed with Spotless 5.5.0

• Run git checkout -f test/5.5.0
• Run git checkout HEAD~1 followed by ./gradlew spotlessApply: Run git diff to see that Spotless has added the copyright header to HelloWorld.java correctly substituting the current year for $YEAR but note that spotlessJava prints a warning (Can't parse copyright year '', defaulting to 2020)
• Run git checkout -f test/5.5.0 followed by ./gradlew spotlessApply: Run git diff to see that Spotless has fixed the copyright header in HelloWorld.java but besides eliminating the extra space before "All Rights Reserved" it has also changed the year to a range 2020-4464 (it gets the 4464 from the zip code in the address in the copyright header)
