spotless:apply for Java does not format unused imports correctly

[FlorianZipser]

When formatting unused imports in Java code with spotless plugin for maven, the imports are removed, but unnecessary lines remain.

Apache Maven 3.6.0
spotless version 1.23

For instance using spotless:apply to the following code

package foo;

import unused

public class Foo{
}

will produce

package foo;


public class Foo{
}

Includeing two linebreaks. This causes spotless:check to fail.

Can you copy-paste your spotless configuration block?

Sure, sorry for the delay:

			<plugin>
				<!-- checks code format -->
				<groupId>com.diffplug.spotless</groupId>
				<artifactId>spotless-maven-plugin</artifactId>
				<version>${spotless.version}</version>
				<executions>
					<execution>
						<phase>verify</phase>
						<goals>
							<goal>check</goal>
						</goals>
					</execution>
				</executions>
				<configuration>
					<java>
						<googleJavaFormat>
							<version>${google-java-format.version}</version>
							<style>GOOGLE</style>
						</googleJavaFormat>
						<removeUnusedImports />
					</java>
				</configuration>
			</plugin>

As of maven-plugin 1.31.0, paddedcell is always enabled, which would fix this problem. Fixed by #565
