Question

I am using Maven 2.x, Atlassian Bamboo with maven plugin my build jdk configuration is set to 1.6 and i don't have any jdk version enforced setting in pom.xml file.

Answer 1

Add the below properties to your pom.xml.

<properties>
    <maven.compiler.target>1.6</maven.compiler.target>
    <maven.compiler.source>1.6</maven.compiler.source>
</properties>

Answer 2

Another way that doesn't involve modifying the pom is to specify the source and target in the command line:

mvn install -Dmaven.compiler.source=1.6 -Dmaven.compiler.target=1.6

Note that this should be avoided generally as the build cannot be guaranteed to be repeatable this way.
