fmt-maven-plugin

Formats your code using google-java-format which follows Google's code styleguide.

The format cannot be configured by design.

If you want your IDE to stick to the same format, google-java-format also includes integrations for IntelliJ and Eclipse IDE's, following the installation instructions on the README.

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>2.10</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>2.10</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>check</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

Options

sourceDirectory represents the directory where your Java sources that need to be formatted are contained. It defaults to ${project.build.sourceDirectory}

testSourceDirectory represents the directory where your test's Java sources that need to be formatted are contained. It defaults to ${project.build.testSourceDirectory}

additionalSourceDirectories represents a list of additional directories that contains Java sources that need to be formatted. It defaults to an empty list.

verbose is whether the plugin should print a line for every file that is being formatted. It defaults to false.

filesNamePattern represents the pattern that filters files to format. The defaults value is set to .*\.java.

skip is whether the plugin should skip the operation.

skipSortingImports is whether the plugin should skip sorting imports.

style sets the formatter style to be google or aosp. By default this is 'google'. Projects using Android conventions may prefer aosp.

example:

<build>
    <plugins>
        <plugin>
            <groupId>com.coveo</groupId>
            <artifactId>fmt-maven-plugin</artifactId>
            <version>2.10</version>
            <configuration>
                <sourceDirectory>some/source/directory</sourceDirectory>
                <testSourceDirectory>some/test/directory</testSourceDirectory>
                <verbose>true</verbose>
                <filesNamePattern>.*\.java</filesNamePattern>
                <additionalSourceDirectories>
                    <param>some/dir</param>
                    <param>some/other/dir</param>
                </additionalSourceDirectories>
                <skip>false</skip>
                <skipSortingImports>false</skipSortingImports>
                <style>google</style>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>format</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

check Options

displayFiles default = true. Display the list of the files that are not compliant

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

style sets the formatter style to be google or aosp. By default this is 'google'. Projects using Android conventions may prefer aosp.

example to not display the non-compliant files:

<build>
    <plugins>
        <plugin>
            <groupId>com.coveo</groupId>
            <artifactId>fmt-maven-plugin</artifactId>
            <version>2.10</version>
            <configuration>
                <displayFiles>false</displayFiles>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>check</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

example to limit the display up to 10 files

<build>
    <plugins>
        <plugin>
            <groupId>com.coveo</groupId>
            <artifactId>fmt-maven-plugin</artifactId>
            <version>2.10</version>
            <configuration>
                <displayLimit>10</displayLimit>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>check</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Command line

You can also use it on the command line

mvn com.coveo:fmt-maven-plugin:format

You can pass parameters via standard -D syntax. mvn com.coveo:fmt-maven-plugin:format -Dverbose=true

-Dfmt.skip is whether the plugin should skip the operation.

Using with Java 8

Starting from version 1.8, Google Java Formatter requires Java 11 to run. Incidently, all versions of this plugin starting from 2.10 inclusively also require this Java version to properly function. The 2.9.x release branch is the most up-to-date version that still runs on Java 8.

Deploy

git tag v0.0.0

mvn versions:set -DnewVersion=0.0.0
mvn clean deploy -P release
