Oh my god, but where is m2e?

Since yesterday's release of Indigo, there seems to have been some confusion about where m2e can be found. So here are some answers for you:

- m2e is now a project of the Eclipse Foundation: http://www.eclipse.org

- The landing page for the project is: http://www.eclipse.org/m2e

- Bug reports go there: https://bugs.eclipse.org/bugs/enter_bug.cgi?product=m2e and

- User mailing list: https://dev.eclipse.org/mailman/listinfo/m2e-users

- Dev mailing list: https://dev.eclipse.org/mailman/listinfo/m2e-dev

Where can you download m2e from?

- m2e comes prepackaged in the Eclipse IDE for Java Developers

- it is also available from the indigo repository (http://download.eclipse.org/releases/indigo) and can be installed using Help > Installed New Software...

Why does m2e not ship in the Eclipse IDE for Java EE Developers package?

Long story short, this is because at the time we made the decision where to include m2e, the future of the m2e/WTP integration was uncertain. However, since then the situation has changed with Fred Bricon being hired by JBoss and have him be focused on this piece of technology.

In the meantime, I have opened an enhancement request https://bugs.eclipse.org/bugs/show_bug.cgi?id=350150 to get m2e added to the JEE package.

So in short, m2e is here, it is available, go use it.

From Helios to Indigo is easy

Indigo is now out. You've been running Helios for quite a while and have added tons of plug-ins on top of it and you don't really want to have to craft that install again. Here are below a few possibilities to ease with the update:

Possibility 1 - Morphing Helios into Indigo

The idea here is that you will upgrade your Helios install into an Indigo one. If all plug-ins have been playing nicely in specifying their version ranges and using APIs, this should just work. Otherwise you will get presented with errors messages having unsatisfiable dependencies. Anyway, here are the steps:

Step 1: Add the http://download.eclipse.org/releases/indigo to the set of repositories (Preferences > Install Updates > Available Software Sites).

Step 2: Search for updates: Help > Check for Updates. Note that this will search for updates for all the plugins that are installed. If you want a more selective update, try Help > About > Installation Details and select the entries you are interested in updating among the elements listed in the Installed Software tab (see pictures below).

Step 3 : Once prompted with the available updates, select the desired items, click next a couple times and patiently wait for the bytes to download to your machine. Then restart and enjoy!

Possibility 2 - Start fresh and install plugins from an old install

The idea here is that you want to keep your old install intact, download a new indigo package (http://download.eclipse.org/) and just adds the existing plugins to your install. With Indigo this is now made super easy!

Step 1: Download and unzip your Indigo install: http://download.eclipse.org

Step 2: Import your plug-ins from your previous install by doing File > Import > Install > From existing install, pick your old install, select the plug-ins and there you go! You can chose to go piece meal, or chose to pick several entries, in any event dependency analysis will be performed to check the validity of the install.

Step 3: Click next a couple times and patiently wait for the bytes to download to your machine. Then restart and enjoy!
