detekt不生成报告

detekt 配置是基于 official documentation :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <inherited>false</inherited>
    <executions>
        <execution>
            <!-- This can be run separately with mvn antrun:run@detekt -->
            <id>detekt</id>
            <phase>validate</phase>
            <configuration>
                <target name="detekt">
                    <java taskname="detekt" dir="${project.basedir}"
                          fork="true"
                          failonerror="false"
                          classname="io.gitlab.arturbosch.detekt.cli.Main"
                          classpathref="maven.plugin.classpath">
                        <arg value="--input"/>
                        <arg value="${project.basedir}/src/main/kotlin"/>
                        <arg value="--config"/>
                        <arg value="${project.basedir}/src/main/resources/sv_detekt.yml"/>
                        <arg value="--filters"/>
                        <arg value=".*/test/.*,.*/target/.*,.*/resources/.*"/>
                        <arg value="--output"/>
                        <arg value="${project.build.directory}/detekt-reports"/>
                        <arg value="--output-name"/>
                        <arg value="checkstyle-result"/>
                        />
                    </java>
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>io.gitlab.arturbosch.detekt</groupId>
            <artifactId>detekt-cli</artifactId>
            <version>1.0.0.RC8</version>
        </dependency>
    </dependencies>
</plugin>

然后,我试图通过以下命令执行它: mvn antrun:run@detekt

$ mvn antrun:run@detekt

看起来不错,但是文件夹 ${project.build.directory}/detekt-reports
