Fred Bricon [http://community.jboss.org/people/fbricon] modified the blog post: "m2e(clipse)-wtp 0.13.1 : Back to the m2e marketplace" To view the blog post, visit: http://community.jboss.org/community/tools/blog/2011/08/01/m2eclipse-wtp-... -------------------------------------------------------------- As I mentioned in the previous blog post ( http://community.jboss.org/en/tools/blog/2011/06/23/m2eclipse-wtp-0130-ne... http://community.jboss.org/en/tools/blog/2011/06/23/m2eclipse-wtp-0130-ne...), 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 : http://community.jboss.org/servlet/JiveServlet/showImage/38-4023-16816/m2... http://community.jboss.org/servlet/JiveServlet/downloadImage/38-4023-1681... 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. http://community.jboss.org/servlet/JiveServlet/showImage/38-4023-16814/m2... http://community.jboss.org/servlet/JiveServlet/downloadImage/38-4023-1681... 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) http://community.jboss.org/servlet/JiveServlet/showImage/38-4023-16815/m2... http://community.jboss.org/servlet/JiveServlet/downloadImage/38-4023-1681... 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&v... https://issues.sonatype.org/secure/ReleaseNote.jspa?projectId=10310&v...). *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. https://twitter.com/#%21/fbricon https://twitter.com/#!/fbricon -------------------------------------------------------------- Comment by going to Community [http://community.jboss.org/community/tools/blog/2011/08/01/m2eclipse-wtp-...]
