Answer 1

You are trying to test the app not build it. Anyway, if you really want to build it and skip test, you should run

mvn clean install -DskipTest

Answer 2

The Surefire Plugin is used during the test phase of the build lifecycle to execute the unit tests of an application

either you can skip the test or if you still want to build the project even if there are test failures then you can use **<testFailureIgnore>true</testFailureIgnore>** in pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M4</version>
     <configuration>
    <testFailureIgnore>true</testFailureIgnore>
    </configuration>
 </plugin>

Answer 3

Use this option -Dmaven.test.failure.ignore
