jasper-reports plugin does not take Maven's compiler settings into account
--------------------------------------------------------------------------
Key: MOJO-1565
URL: http://jira.codehaus.org/browse/MOJO-1565
Project: Mojo
Issue Type: Bug
Components: jasperreports
Environment: WindowsXP, Java 1.5 & 1.6, Maven
Reporter: Tom Eugelink
Priority: Critical
I have a Maven project that uses both Java 1.6 and 1.5; there is an applet that
is run under 1.6, but the server backend under 1.5. The project is setup as
components, each pom specifies which java version to use.
When the toplevel pom is called which (will build all components), this needs
to be done under java 1.6, otherwise the applet won't compile correctly. The
regular java code is compiled as specified in the pom; the applet with 1.6, the
server side with 1.5. But the Jasper reports seem to be compiled using the
active java (1.6) and not the specified one (1.5), so I get bad class version
numbers.

The plugin should either take the specified java version into account or be
able to acccept compiler version information.
