Sonatype recently announced the availability of m2eclipse 0.12. This release includes support for Maven 3.0 and many improvements in the HTTP transport code. This should be the last release made available from the Sonatype servers. But not to worry, we are not stopping the development. In fact, quite conversely, we are ramping up our efforts on the m2eclipse core and moving m2e to the Eclipse foundation.
At this point, the move has not been completed as we are still working with the Eclipse IP team to get all our code and dependencies reviewed. If all goes well, we are hoping to have everything moved to the Eclipse Foundation by mid-December. In the meantime the development is still happening on github but under the new org.eclipse.m2e name-space. We will keep you posted when the code has been completed moved.
