To show Checkstyle analysis results, print the Checkstyle result XML to the build log.

...

Using Checkstyle Command Line

Use the -f=xml flag to print out the Checkstle analysis into the build log. For example:

java -jar ~/Downloads./checkstyle-9.3-all.jar -c=/sun_checks.xml -f=xml src/main/java/

...

Using Maven Checkstyle

The Maven Checkstyle plugin doesn’t support printing the XML into the logs. Instead Configure Checkstyle in Maven first:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>3.1.2</version>
    <executions>
        <execution>
            <id>validate</id>
            <phase>validate</phase>
            <goals>
                <goal>checkstyle</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Then print the generated target/checkstyle-result.xml file into the build log by a final task:

#!/bin/bash
cat ./target/target/checkstyle-result.xml || echo "No Checkstyle analytics generated"

...

...

Using Gradle Checkstyle

The Gradle Checkstyle plugin doesn’t support printing the XML into the logs. Instead print the generated ./build/reports/checkstyle/main.xml file into the build log by a final task:

#!/bin/bash
cat ./build/reports/checkstyle/main.xml  || echo "No Checkstyle analytics generated"

...

...

Using Checkstyle via other Build System

Typically the build system tool generate a Checkstyle report xml. Dump that to the console by a final task. For example:
