Trying to install m2e-egit via Eclipse Marketplace causes installation error

[christianbalzer]

Steps to reproduce:
File > Import... > Maven > Check out maven project from SCM > Next > m2e Marketplace Link > Find: EGit > Select: m2e-egit > Finish > Next > Finish

Error message:

Just got this error with a clean install of Eclipse Photon:

@neerup workaround does not work for me. I added the suggested URL and tried installing m2e-egit again. I now get the following (slightly different error):

@fcarsten From a clean install of Photon I just added the above Update site and installed the m2e extensions -> Maven SCM Handler for EGit from the Install New Software... menu.
No need for the Marketplace

Add
http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-egit/0.15.1/N/LATEST/
Maven SCM Handler for EGit Repository

To Your update sites

Just installed.
After open eclipse(my case, photon)

Help > Install New Software... > Add..

Name: m2eclipse-egit
Location: http://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-egit/0.15.1/N/LATEST/

Then in "Work with:" drop down select the "new location just added, then m2e extensions display as: "Maven SCM Handler for EGit"

[fcarsten]

@billson-my This works for me. Thanks.

I have the same issue when I try to install the m2eclipse-egit connector in Eclipse 2019-06 and the solution mentioned above also works for me. But is it possible to update the m2e discovery catalog so that Eclipse users can install m2eclipse-egit "out of the box"?

[praveenshukla]

This fix worked for me. Thank you!

[PyvesB]

I submitted a pull request to update the catalog entry (see link above). This should fix the issues reported here. 😉

Fresh install of Eclipse 2021-12 and installation of m2e-egit fails with the following:

Cannot complete the install because one or more required items could not be found.

Install fails whether using m2e-marketplace or 'install new software' using the 0.15.1 location.

EDIT: Can only get m2e-egit working in 2021-12 by downgrading the default eGit 6.0 installation to 5.13.
