It provides a set of m2e connectors configuring Java EE projects in WTP, from their maven plugin configuration.
m2e-wtp also brings some advanced Maven features to the IDE, such as dynamic resource filtering or war overlays.
m2e 1.1.0 is a maintenance release with a focus on bug fixes. The main new feature is the ability to enable/disable m2e-wtp entirely, either from Eclipse Preferences or from Maven properties defined in pom.xml. XML templates are provided for such properties in the pom editor. More details are available at https://wiki.eclipse.org/M2E-WTP/New_and_Noteworthy/1.1.0
m2e 1.1.0 requires m2e 1.5.0 and is compatible with Eclipse Kepler and Luna releases.
