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:

!MESSAGE An internal error occurred during: "Enable debugging and flush log cache". !STACK 0 java.lang.NoClassDefFoundError: org/eclipse/osgi/framework/internal/core/FrameworkProperties at com.aptana.core.util.EclipseUtil.setPlatformDebugging(EclipseUtil.java:449)

How can I solve this error?

Development version of Aptana plugin seems to work fine with Eclipse Luna. Use 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.
