Maven Compiler Plugin Configuration

The fist step to build a java application is to be able to compile a maven projet . According to the dependencies created in the POM file (Project object model) Maven is able to define the classpath and compile using the default jdk using the following command :

mvn compile

Maven compile incrementally. An incremental build reuses the results of a previous build to perform an optimized build based on the changes since the last build. If your code has been compiled by Eclipse you can have some surprises due to some tips and tricks used by the Eclipse compiler. To ensure a full compilation by the default Sun JDK you should make a cleanup before compiling. It will delete the previously compiled classes contained in the {project directory}/target/classes

mvn clean compile

If you want to compile without your Unit test defined in {project directory}/src/test/java your can ask maven to skip the test

mvn compile -DskipTest=true

Compiler version

If you need to define the compiler version you can set the source and target parameter in the Compiler Plugin :

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.6</source>
    <target>1.6</target>
  </configuration>
</plugin>
