Maven Plugins

Q- What are the plugins used in maven? Or What are common maven plugins?

maven-compiler-plugin: This plugin is used to compiles our Java code from the standard location Maven specifies e.g. /src/main/java and /src/main/resources.

<build>
    <sourceDirectory>src</sourceDirectory>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
