Problem installing Maven plugin (m2eclipse) in Eclipse (Galileo)

I have Eclipse Galileo (for Java EE Developers) installed, and I'm now trying to get the m2eclipse开发者_开发百科 Maven plugin installed as well.

I follow the basic steps described at http://m2eclipse.sonatype.org/installing-m2eclipse.html, and it seems to be installing just fine. However, after restarting Eclipse after the install it doesn't seem to be anywhere. I should for instance have the ability to create a new maven project, but when the new-project wizard opens, there is no folder for Maven (I also cannot find any reference to it in the context menus of the existing projects I have).

When I click at Help > About Eclipse > Installation Details, I find "Maven Integration for Eclipse (Required)" in the tab "Installed Software", yet another thing pointing towards a successful installation (but I can't find it under the "Plug-ins" tab, should it be there too?)...

I feel like I'm just missing something very obvious, but right now I just don't see it...

I managed to find the answer to this myself:

I had put the Eclipse installation folder under c:\Program Files\, but when I moved it directly under c:\ instead, the plug-in installation worked just as it should. I assume that is because Eclipse wasn't allowed to write to its own installation folder (but I didn't get the usual question from Windows that something was trying to access Program Files either...).

In one way I feel like I should be a bit ashamed that I didn't think of this before. On the other hand though, there could have been some reasonable error message stating that something failed during the plug-in installation...

Well, I hope this at least helps somebody else as well :)

Did you check the m2eclipse installation requirements?
In particular, you need WTP.

"Maven integration for Eclipse" (core feature) and optional "Maven POM Editor" feature depend on the "Eclipse XML Editors and Tools" feature from WST
"Maven integration for WTP" feature provides Maven project configuration for WTP

Did you have a previous version of m2eclipse installed? Did you uninstall it before to install the latest version? Just in case, does the following note applies to you?

Note about 0.9.8 Workspace Incompatibility: If you are using m2eclipse 0.10.0 with a workspace that contains projects created under m2eclipse 0.9.8, you must remove the workspaceState.ser file. The workspaceState.ser file is located within the workspace directory in $workspacedir/.metadata/.plugins/org.maven.ide.eclipse/workspaceState.ser. If you remove this file, m2eclipse 0.10.0 will regenerate it as needed.

In my case, uninstalling the previous m2eclipse version didn't work and I had to start with a fresh Eclipse install (maybe try this also).

Regarding the plugin tab, this is what I have (to confirm that you should definitely find something):

Note that I also installed some extras from m2eclipse Extras Update Site: http://m2eclipse.sonatype.org/sites/m2e-extras

I was able to solve this problem by going into Program Files, right click on the eclipse.exe file and select "Run as administrator". When I restarted Eclipse it said I had no plugins installs so I reinstalled and my problems were solved.

PROBLEM SOLVED I had this same problem and I used the following software site: ["M2Eclipse - http://download.eclipse.org/technology/m2e/releases/1.0] (without square brackets) to download the M2Eclipse plugin in Eclipse 3.7.0 (Indigo). For more information refer this.

To solve the problem of 'not getting Maven plugin running in eclipse' , it can be solved by altering admin rights to the .m2 folder . Right click on .m2 folder and go to network sharing. give all rights to all users. Restart eclipse and maven options will start to appear in Eclipse.
