Common Checkstyle Config

Externalized checkstyle configuration which can be used in other Maven projects.

Description

This is a hand-picked, incrementally improved checkstyle configuration. It is more on the liberal side as I believe tools should work for the user not the other way around. Code style is subjective and this one might not be for you.

Usage

Add this maven project as dependency to load the external checkstyle configuration. The name of the config xml is checkstyle.xml.

    <build>
        <plugins>
            <!-- checkstyle -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-checkstyle-plugin</artifactId>
                ...
                <dependencies>
                    ...
                    <!-- add this lib as dependency to load external checkstyle config -->
                    <dependency>
                        <groupId>at.favre.lib</groupId>
                        <artifactId>checkstyle-config</artifactId>
                        <version>{latest_version}</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <configLocation>checkstyle.xml</configLocation>
                </configuration>
            </plugin>
            ...
