Understanding Maven Build Phases

Which Maven build phase is responsible for compiling the source code of a project?

A compile

B test

C package

D install

💡 Hint

Think about when the source code is turned into bytecode.

The compile phase compiles the source code of the project. Other phases like test run tests, package creates the distributable, and install puts the package into the local repository.

Maven Default Lifecycle Execution Result

What will be the final output directory after running mvn package on a standard Maven project?

A target

B target/test-classes

C target/classes

D src/main/resources

💡 Hint

Where does Maven put the packaged jar or war file?

Running mvn package compiles and packages the project, placing the output (like jar or war) in the target directory.

Correct Assertion for Maven Build Success

Which assertion correctly verifies that a Maven build executed successfully in a Java Selenium test using ProcessBuilder?

Selenium Java

ProcessBuilder builder = new ProcessBuilder("mvn", "clean", "install");
Process process = builder.start();
int exitCode = process.waitFor();

A assertNull(exitCode);

B assertTrue(exitCode > 0);

C assertFalse(exitCode == 0);

D assertEquals(0, exitCode);

💡 Hint

A successful Maven build returns exit code zero.

Maven returns 0 on success. The assertion assertEquals(0, exitCode); confirms the build succeeded.

Debugging Maven Build Failure

Given the Maven command mvn clean install fails with a test failure, which option best describes the cause?

A Source code in src/main/java failed to compile

B The package phase did not create the jar file

C Tests in src/test/java failed during the test phase

D The install phase did not copy the artifact to the remote repository

💡 Hint

Test failures stop the build during the test phase.

If tests fail, Maven stops the build during the test phase, causing mvn clean install to fail.

Integrating Maven with Selenium Tests

Which Maven plugin configuration is required to run Selenium WebDriver tests during the Maven test phase?

A

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-install-plugin</artifactId>
  <version>2.5.2</version>
</plugin>

B

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>3.0.0-M5</version>
</plugin>

C

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
</plugin>

D

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <version>3.2.0</version>
</plugin>

💡 Hint

Which plugin runs tests during the test phase?

The maven-surefire-plugin runs unit and integration tests during the test phase, including Selenium WebDriver tests.
