It seems you're right. We use multiple executions but we're bundling all
classes in the end in one jar (only the JDK 5 specific code is compiled
with target JDK 5). I silently assumed, that it is possible to set
different output paths. Setting it using the compiler options directly will
not help, since Maven will have a look at the wrong directory to decide
which classes have to be compiled.

Then all I can propose is my second alternative:
