The maven eclipse plugin (m2e) selects a java execution environment depending on the and properties for the maven compiler plugin.

The problem is that there is neither a 1.8 execution environment available in Kepler nor the m2e maven compiler connector can map it yet.

Thus I see two solutions until it is supported in Kepler and m2e:

Let maven change the environment to 1.4 and map your 1.8 JDK to the execution environment J2SE-1.4. Then your project will use the correct JDK. But then all projects that depend on 1.4 will use the 1.8 JDK of course.

Use the pluginManagenent to turn off the maven-compiler-plugin lifecycle handling. This should prevent the m2e plugin from updating the execution environment and you can set it manually.
