• IntelliJ IDEA

Usage

Standard pom.xml

To have your sources automatically formatted on each build, add to your pom.xml:

    <build>
        <plugins>
            <plugin>
                <groupId>com.coveo</groupId>
                <artifactId>fmt-maven-plugin</artifactId>
                <version>2.2.0</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>format</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

If you prefer, you can only check formatting at build time using the check goal:

    <build>
        <plugins>
            <plugin>
                <groupId>com.coveo</groupId>
                <artifactId>fmt-maven-plugin</artifactId>
                <version>2.2.0</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>check</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

                <verbose>true</verbose>
                <filesNamePattern>.*\.java</filesNamePattern>
                <additionalSourceDirectories>
                    <param>some/dir</param>
                    <param>some/other/dir</param>

displayLimit default = 100. Number of files to display that are not compliant`

example to not display the non-compliant files:

<build>
    <plugins>
        <plugin>
            <groupId>com.coveo</groupId>
            <artifactId>fmt-maven-plugin</artifactId>

                </execution>
            </executions>
