error in installing mercurial plugin for eclipse

Mercurial Eclipse Plugin

Answer 1

The key part of the error message is "requires 'bundle org.eclipse.jface.text 3.11.0'".

This is saying that at least version 3.11.0 of the org.eclipse.jface.text plugin is required. This version of the plugin was first released in Eclipse Neon (4.6) - so your Eclipse Luna is too old. You will need to move to a newer version of Eclipse to use this plugin.

Answer 2

I am the current maintainer of MercurialEclipse. Like Greg said, you are facing this error message because you are trying to install the plugin on a platform with which it is not compatible.

The last couple of major releases require Neon, which is for the foreseeable future the baseline. This requirement for Neon is in turn due to a requirement for Java 8 in JavaHg and (if I'm not mistaken) Eclipse itself.

It is unfortunate that users cannot have a more explicit error message such as "this plugin requires Eclipse Neon or later versions".

FYI, Release Notes are published on the very website you linked to on Bitbucket. You will also find in the Wiki a compatibility table with Mercurial proper, as well as with Eclipse. I also state the requirements or other impacting changes when I send the release announcement e-mail.

Answer 3

It is not good solution, but I can see it work: just ask other guys copy the 2.1 version files to you, and you can place them in eclipse feature & plugin folders.

The files are:
1. \features\mercurialeclipse_2.1.0.201304290948
2. \plugins\com.vectrace.MercurialEclipse_2.1.0.201304290948.jar
