    This is the most lame solution to a problem I have read in a while.

    I have been getting the same error (on and off) for quite some time now. I have tried everything, re-installed fresh Eclipse and MyEclipse. Works good for a short period of time and then starts showing the error again. I finally got sick of seeing it and did a search to find a solution.

    And all you can reply with is import all your projects to a new workspace? That’s it?!? Do you know how many projects I have defined in my workspace? Why don’t you guys just fix the issue or find out what is causing it? I do not get this when running the standard Eclipse against the same workspace. Which I am very strongly considering making my default IDE again.

    Thanks

    Nick,
    Before we grab our torches and decide to burn folks alive, why don’t you give us some information about your setup, the error you are getting, is it a popup? Is there something written to the log file? What is it? etc.

    There might be a chance that the problem you are seeing is a hair different than the one the original person reported.

    For starters, can you grab the information from MyEclipse > Installation Summary > Installation Details and paste it here for me? Also, can you describe, in detail, the problem you are seeing? Is there some error popup? Or just an error marker on the project? If you go to Window > Show View > Other… > PDE > Errors, can you click the red “X” and clear the log file, then restart, and copy paste the new errors that are created on startup here for me? They might shine some light on what is going on.

    Hi ‘m using Eclipse 3.3 Europa. It’s been working fine up until a few days ago and now just gives this error every single time I start MyEclipse:

    Initializing Java Tooling. Reason: assertion failed: Path for IClasspathEntry must be absolute

    I haven’t made any changes to my projects that I know of, I need a fix quickly because I can’t access my projects now. Whenever I expand on of them, it’s just blank. I’ve checked the properties of the projects and they are pointing to the correct location on my filesystem..

    Your quick response is greatly appreciated.

    Thanks,

    sree

    sree,
    Please see my last post to Nick, I need all that information from you as well and I’d be happy to help (without it, it’s hard to guess what si going wrong)

    I’m getting the exact same symptom…except I get it ALL the time…e.g.: every time clicking ‘Run App’ button.

    I have restart eclipse every 20-30 minutes just to be able to work….VERY annoying.

    Running:
    Eclipse SDK

    Version: 3.3.2
    Build id: M20080221-1800

    MyEclipse Application Server Tooling

    Version: 6.0.1.zmyeclipse601200710
    Build id: 6.0.1-GA-200710
    Here’s what’s in log:

    I don’t know if this is related, but this also shows up in the log in and around the time of the IclassPath error:

    At startup, I get this error:

    mynetwatchman,
    There is a lot going on there and a slew of things that can be causing problems. Thanks for posting all that info, here is what I’m seeing:

    First: You are running MyEclipse with Java 6 Update 10 Beta, which is not certified to run MyEclipse 6 or 6.5. We don’t test with it.

    Second: You have a tone of class not found errors which immediately raise my “Corrupted install” red-flag.

    To rule out these two things at once, and get you back on track, I really think the fastest thing to do is this:

    1. Go to our download page: http://www.myeclipseide.com/module-htmlpages-display-pid-4.html
    2. Download the “All in One” installer for MyEclipse 6.5
    3. Run the installer, make sure you install it to a brand new directory.
    4. Find the shortcut that the installer created inside the MyEclipse 6.5 group and run it using that (just making sure you don’t accidentally use your own shortcut you had setup previously to run MyEclipse).
    5. Go to MyEclipse > Installation Summary > Installation Details, and paste that information here for me please.

    This thread has been quiet for a while, but I wanted to add another data point.

    I just got this error for the first time, and there are two possible factors. First, my system crashed because of a power outage, hence I was not able to exit cleanly (as an earlier post mentions). Second, upon restarting my machine, I decided to upgrade my Java 6 install to Update 7. After reading Riyad’s mention of Update 10 Beta being untested, I decided to uninstall Update 7. Since restarting eclipse with Java 6 update 1, I am no longer seeing the IClasspathEntry error.

    My installation details:

    *** Date:
    Monday, September 15, 2008 10:21:16 AM EDT
