I'm unable to install above via Marketplace. Detailed error for missing dependency is as follows:
Cannot complete the install because one or more required items could not be found. Software being installed: Maven SCM Handler for EGit 0.14.0.201509090157 (org.sonatype.m2e.egit.feature.feature.group 0.14.0.201509090157) Missing requirement: Maven SCM Handler for EGit 0.14.0.201509090157 (org.sonatype.m2e.egit 0.14.0.201509090157) requires 'osgi.bundle; org.eclipse.egit.core [3.0.0,5.0.0)' but it could not be found Cannot satisfy dependency: From: Maven SCM Handler for EGit 0.14.0.201509090157 (org.sonatype.m2e.egit.feature.feature.group 0.14.0.201509090157) To: org.eclipse.equinox.p2.iu; org.sonatype.m2e.egit [0.14.0.201509090157,0.14.0.201509090157]
I noticed this has happened earlier, most often when there is a newer version of Eclipse. Anyway I can't find a certain software site or a valid package to work around it.
Is there anything I can do except go back to Oxygen?
I had the same problem. I managed to get it installed by going to Help -> Install New Software -> Work with: https://repo1.maven.org/maven2/.m2e/connectors/m2eclipse-egit/0.15.1/N/0.15.1.201806191431/
It seems to have installed without any problems, but I must admit, I haven't actually used it yet.
