Welcome to the Maven Compiler Plugin documentation! This guide will help you understand how to configure and use the compiler plugin in your Maven projects. 🔧

What is the Maven Compiler Plugin?

The Maven Compiler Plugin is a core component that manages the compilation of source code in your project. It supports multiple languages including Java, Kotlin, and Scala. 🌐

Key Features

  • Default Compiler: Uses javac for Java projects
  • Custom Configurations: Supports specifying source/target versions
  • Multi-Language Support: Easily extendable for other languages

How to Configure

  1. Basic Setup
    Add the following to your pom.xml:

    <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

  2. Advanced Options

    • Enable annotations: <annotationProcessorPaths>
    • Exclude test sources: <excludeTestSources>true</excludeTestSources>
    • Specify compiler arguments: <compilerArgs>

Common Issues

  • ❌ Compilation error: Unsupported class version
    Solution: Update <source> and <target> versions in pom.xml
