--------------------------------------------------------------
As I mentioned in the previous blog post ( http://community.jboss.org/en/tools/blog/2011/06/23/m2eclipse-wtp-0130-new-noteworthy http://community.jboss.org/en/tools/blog/2011/06/23/m2eclipse-wtp-0130-new-noteworthy), m2e-wtp had to be pulled out of the m2e marketplace, as it forced its installation for all non-WTP systems.

In order to fix this issue, the code responsible for generating the MANIFEST.MF for all projects had to be integrated into the mavenarchiver feature. 
That means m2e-wtp 0.13.1 now requires the installation of mavenarchiver from the m2e-extras update site. It will be discovered automatically from the new m2e-wtp update site, hosted by Red Hat, so it will be completely transparent for new users.
However, please note that the mavenarchiver feature replaces the pomproperties one, so the *pomproperties must be uninstalled before upgrading m2e-wtp*.

Thus, the preferred ways to install m2e-wtp remain :

1) Import existing Java EE projects into the workspace; You'll be proposed to install the m2e-wtp plugin :

click on Finish and the installation will proceed. Your projects will be imported but the workspace will have to be restarted.

2) Go to Window > Preferences > Maven > Discovery and click on "Open catalog". Select m2e-wtp and proceed with the installation.

3) Old school installation : Use this JBoss / Red Hat update site :  http://dev.eclipse.org/mhonarc/lists/m2e-users/msg00938.html http://download.jboss.org/jbosstools/updates/m2eclipse-wtp/  

While reviewing the installation details, you can see that mavenarchiver 0.14.0 will be found and installed automatically (provided there is not a more recent version already installed)

Other that the changes necessary to reinstate m2e-wtp to the m2e marketplace, There is only one other bugfix in 0.13.1, which fixes deployment of war archives overlays in Windows ( https://issues.sonatype.org/secure/ReleaseNote.jspa?projectId=10310&version=11271 https://issues.sonatype.org/secure/ReleaseNote.jspa?projectId=10310&version=11271).

*UPDATE (03/08/2011) :* m2e-wtp is now also available from the  http://marketplace.eclipse.org/content/maven-integration-eclipse-wtp Eclipse Marketplace. However, it seems some people are unable to install it directly. Please note that m2e-wtp requires m2e 1.0. So, if it's not installed already, Eclipse must be able to find it in the available update sites. 
m2e can be installed from either  http://download.eclipse.org/releases/indigo http://download.eclipse.org/releases/indigo (for Indigo) or  http://download.eclipse.org/technology/m2e/releases/ http://download.eclipse.org/technology/m2e/releases/ (for Helios and Indigo).
The change in m2e's namespace (org.maven.ide -> org.eclipse.m2e) between m2e 0.12.x and 1.0 renders updates impossible from m2e-wtp 0.12.x to 0.13.x. Thus you have no choice but to uninstall m2e < 1.0 and m2e-wtp < 0.13 before proceeding with m2e-wtp 0.13.x's installation.
(I hope I'm clear enough :-))

Enjoy,

Fred.
