Question

In Maven, I have a codebase that I want to build that needs to target the 1.4 JVM. This is very easy to do in the pom, but I have one problem: The tests for this codebase use 1.5+ constructs.

Is it possible to have Maven compile/run the tests inside a 1.6 JVM, but build the main codebase to target 1.4?

Setting source to 1.6 and target to 1.4 don’t work. Maven/Java don’t allow this combination.

I was able to achieve what I wanted with this:

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>2.3.2</version>
          <configuration>
            <testSource>1.6</testSource>
            <testTarget>1.6</testTarget>
            <target>1.4</target>
            <source>1.4</source>
          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
