Description

Because pom projects do not have Java code, It is not necessary to create "target/checkstyle-cachefile", "target/checkstyle-checker.xml", "target/checkstyle-result.xml" and "target/checkstyle-suppressions.xml" files for these projects.

Maven configuration:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-checkstyle-plugin</artifactId>
	<version>3.2.1</version>
	<dependencies>
		<dependency>
			<groupId>com.puppycrawl.tools</groupId>
			<artifactId>checkstyle</artifactId>
			<version>10.9.3</version>
		</dependency>
	</dependencies>
	<configuration>
		<configLocation>checkstyle.xml</configLocation>
		<suppressionsLocation>checkstyle-suppressions.xml</suppressionsLocation>
		<includeTestSourceDirectory>true</includeTestSourceDirectory>
		<violationSeverity>info</violationSeverity>
	</configuration>
	<executions>
		<execution>
			<id>checkstyle-check</id>
			<phase>validate</phase>
			<goals>
				<goal>check</goal>
			</goals>
		</execution>
	</executions>
</plugin>

Maven output:

[INFO] --- checkstyle:3.2.1:check (checkstyle-check) @ parent-project ---
[INFO] You have 0 Checkstyle violations.

Content of the generated "target/checkstyle-result.xml":

<?xml version="1.0" encoding="UTF-8"?>
<checkstyle version="10.9.3">
