Reporting Bugs

There may be errors in the /.metadata/.log or even on stdout that can help you track down and problem.
When reporting errors, please include stack traces when applicable and the commit id or the version your plugin is built from, or the version of the plugin if it does not contain a date.


EMF Compare can be built using maven from within the sub-folder of this repository :

mvn clean package -Pmars

The above example will build the EMF Compare binaries against a Mars platform. Select the appropriate profile according to the platform you wish to install EMF Compare on, one in [mars, luna, kepler, juno, indigo, helios, galileo].

You can also check the tests using

mvn verify -Pmars --fail-at-end -Dmaven.test.failure.ignore=true
