Some of the buttons in eclipse don’t work

Some time ago I realized that some of the buttons in my eclipse don’t work. I mean that I can’t press it by clicking, but I can press it using keyboard. To fix it… I had to create new file.

m2eclipse: Eclipse is running in a JRE, but a JDK is required

After a while I sat to one of my old projects again… web-based JEE system to manage requirements of the projects, with maven as a system to manage this project’s dependencies. I work on eclipse, so I wanted to install plugin m2eclipse. However at the end of the installation, after restart of eclipse, I have an error: “The Maven Integration requires that Eclipse be running in a JDK, because a number of Maven core plugins are using jars from the JDK. (…)”. How to solve it?

Eclipse + Subclipse + SVN SSH

Download and run eclipse

Eclipse’s plugins that I use

For me… three plugins for eclipse is enough…
