What are Maven Plugins?

Maven is actually a plugin execution framework where every task is actually done by plugins. Maven Plugins are generally used to −

create jar file
create war file
compile code files
unit testing of code
create project documentation
create project reports

A plugin generally provides a set of goals, which can be executed using the following syntax −

mvn [plugin-name]:[goal-name]

For example, a Java project can be compiled with the maven-compiler-plugin's compile-goal by running the following command.

mvn compiler:compile

Plugin Types

Maven provided the following two types of Plugins −

Sr.No.	Type & Description
1	Build plugins They execute during the build process and should be configured in the <build/> element of pom.xml.
2	Reporting plugins They execute during the site generation process and they should be configured in the <reporting/> element of the pom.xml.

Sr.No.

Type & Description

Build plugins

They execute during the build process and should be configured in the <build/> element of pom.xml.

Reporting plugins

They execute during the site generation process and they should be configured in the <reporting/> element of the pom.xml.

Following is the list of few common plugins −

Sr.No.	Plugin & Description
1	clean Cleans up target after the build. Deletes the target directory.
2	compiler Compiles Java source files.
3	surefire Runs the JUnit unit tests. Creates test reports.
4	jar Builds a JAR file from the current project.
5	war Builds a WAR file from the current project.
6	javadoc Generates Javadoc for the project.
7	antrun Runs a set of ant tasks from any phase mentioned of the build.

Example

We've used maven-antrun-plugin extensively in our examples to print data on console. Refer Build Profiles chapter. Let us understand it in a better way and create a pom.xml in C:\MVN\project folder.

<project xmlns = "http://maven.apache.org/POM/4.0.0"

   xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

   xsi:schemaLocation = "http://maven.apache.org/POM/4.0.0

   http://maven.apache.org/xsd/maven-4.0.0.xsd">

   <modelVersion>4.0.0</modelVersion>

   <groupId>com.companyname.projectgroup</groupId>

   <artifactId>project</artifactId>

   <version>1.0</version>

   <build>

      <plugins>

         <plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-antrun-plugin</artifactId>

            <version>1.1</version>

            <executions>

               <execution>

                  <id>id.clean</id>

                  <phase>clean</phase>

                  <goals>

                     <goal>run</goal>

                  </goals>

                  <configuration>

                     <tasks>

                        <echo>clean phase</echo>

                     </tasks>

                  </configuration>

               </execution>

            </executions>

         </plugin>

      </plugins>

   </build>

</project>

Next, open the command console and go to the folder containing pom.xml and execute the following mvn command.

C:\MVN\project>mvn clean

Maven will start processing and displaying the clean phase of clean life cycle
