1. How do you run the unit test of a specific class's method with maven?

If you specify it in the format package name.file name#method name in the -Dtest= option, you can run the method you want. In Maven, the -D option is the option for specifying a system property.

$ mvn -h #See Maven options
$ mvn clean test -Dtest=com.tmoncorp.media.common.util.FileUtilTest#getFileNameBaseCurrentTimestamp -Dmaven.test.skip=true

2. webxml attribute is required... when running Maven?

$ mvn clean package

The solution for the case where the error "webxml attribute is required..." occurs during maven compilation is as follows.

1. If the servlet container is 3 or lower, you need to create WEB-INF/web.xml
2. If the servlet container is 3 or higher and there is no web.xml, configure it to be ignored by setting failOnMissingWebXml=false

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <configuration>
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>
    </plugins>
</build>
