I use the following workaround.

Install a new maven installation and do not use the embedded version.

I download the version from https://archive.apache.org/dist/maven/maven-3/3.5.3/binaries/.

@Shukant This bug only occurs in Photon M7 and was solved in Photon RC1 which will be available this week.

It's now fixed, just update your Eclipse through Menu -> Help -> Check for Updates. :D

This is a bug in m2e's build, the jars of the Embedded Maven runtime were digitally signed with Eclipse's certificate, messing things up. See Bug 534933 for more details.

Anyways, a fix has been deployed for Photon RC1 and is available at http://download.eclipse.org/technology/m2e/milestones/1.9/
