The Maven Compile Plugin is used to compile all the source code for your project.
Goals:
- compiler:compile is bound to the compile phase and is used to compile the main source files.
- compiler:testCompile is bound to the test-compile phase and is used to compile the test source files.
Configurations:
1. Compile using a different JDK: Following configuration sets the version of the compiler to 1.8.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<verbose>true</verbose>
<fork>true</fork>
<executable>C:\Program Files\Java\jdk1.8.0\bin\javac</executable>
<compilerVersion>1.3</compilerVersion>
</configuration>
</plugin>
</plugins>
</build>
2. Compile using different source and target versions of java compiler: Following configuration sets the source and target version to 1.8.
