Difference between eclipse pulsar, mtj, me

Question

Hi all!, what is difference between eclipse pulsar, eclipse mtj, and eclipse me ?

Answer 1

• Eclipse ME is an external project started in 2003. As its page says:

EclipseME has graduated to become the new Eclipse Mobile Tools for Java (MTJ) project.
The MTJ project provides all of the functionality from EclipseME 1.7.9 plus many new features and lots of bug fixes. The EclipseME project will remain open indefinitely*, but there will be no new releases of EclipseME*.

• Eclipse MTJ is part of the larger DSDP (Device Software Development Platform) set of projects, which addresses a broad range of needs in the device software development space using the Eclipse platform.

MTJ is a project which "will develop frameworks that can be extended by tool vendors and tools that can be used by third-party developers."

• Eclipse Pulsar takes advantage of the MTJ framework and provides a "tools integration platform" (as opposed to "an Eclipse with a plugin for mobile development".
  It is a package (an Eclipse distribution).

As Chris Aniszczyk says in his blog post:

The other new package is Pulsar which was built specifically for the Mobile Java community.
Pulsar is essentially a mashup of the Eclipse SDK and the Eclipse MTJ projects with the ability of downloading more tools from different handset manufacturers.

You can compare the Pulsar package with other Eclipse packages here.

So:

External Plugin (ME) => official Eclipse project (MTJ) => Full Eclipse distribution (package, with Pulsar)
