An internal error occurred during: "Enable Debugging and Flush log Cache". Org/eclipse/osgi/framewor

It seems the environment works properly, but I get the "error every time I open the program.

Here is the log:

How can I solve this error?

Development version of Aptana plugin seems to work fine with Eclipse Luna. Use the this link for installation instead of stable one:

http://studio-jenkins.appcelerator.org/job/studio3-feature-development/lastSuccessfulBuild/artifact/dist/

Use it with Eclipse Luna standard Edition instead of Eclipse Luna for PHP developers. After installation switch to a WEB perspective and configure as you need.
