I just upgraded to 4.0M3 on Eclipse 3.1 and tried creating a UML repository file. When I do, I get a dialog box “Creation problems” popping up with the message “Internal error: {0}”.

eclipse build: Version: 3.1.0
Build id: I20050627-1435

myEclipse build: 4.0 Milestone 3(3.9.310)
Build Id: 20050808-4.0-Milestone-3

Can you try restarting your install with -clean on the command line (eclipse.exe -clean). This rebuilds the plugin cache and solves a huge class of install / upgrade problems.

[Andrew Shackleton]

No go.

Here’s my shortcut: C:\eclipse\eclipse.exe -clean -server -vmargs -Xms128M -Xmx512M -Dosgi.splashLocation=”C:\MyEclipse\MyEclipseSplash.bmp”

I am running into this same problem. System: FC4 Linux, JDK1.5.0_06; Eclipse Build id: M20050929-0840; MyEclipse Build id: 20051025-4.0.3-GA; Command-line: eclipse -vmargs -Xms128M -Xmx512M . Any news on a work-around or fix?

[Kapil Kapre]

Are there any exceptions in your log ? (<workspace>/.metadata/.log)

[mansley]

Hi,

Thanks for the response. Below is the log for an error that I have just generated. I have a selection of others, but they are all basically the same. UI response is as described in this thread.

Thats really strange, could you please make sure that MyEclipse is installed properly (perhaps try with another install location)? Try invoking eclipse with -clean too.

[mansley]

Hi Kapil,

I’ve already done the -clean thing, and I’ve reinstalled at least once, although not to a different directory. I will try this, but the directory that I’m using is not a dubious directory (spaces or anything). I use ~/devapps for my development tool stack, so eclipse is in ~/devapps/eclipse, and MyEclipseIDE is in ~/devapps/MyEclipse. I will try once more using the default ~/MyEclipse and let you know.

Cheers…

Mike

[mansley]

Hi again,

I’ve installed MyEclipseIDE into ~/MyEclipse, and the same problem occurs as before. One thing that I failed to mention is that I have both 1.4 and 1.5 jdks installed. I run eclipse using a shell script (see below) that changes JAVA_HOME to the 1.5 jdk, and puts the 1.5 jdk bin directory into the PATH, at the front, so that it’s ahead of any 1.4 stuff. This shouldn’t cause any problems, but I guess there may be something that I haven’t thought of here. Is it possible that the code in question is looking for a jdk 1.5 class, but searching the jdk 1.4 libraries?

eclipse.sh shell script:
export JAVA_HOME=/usr/java/jdk1.5.0_06
export PATH=$JAVA_HOME/bin:$PATH
export ECLIPSE_HOME=/home/mikea/devapps/eclipse
$ECLIPSE_HOME/eclipse -vm /usr/java/jdk1.5.0_06/bin/java $*

The script is called using the following:
eclipse.sh -vmargs -Xms128M -Xmx512M

Cheers…

Mike

[mansley]

I’ve just tried it with the jdk 1.4 installation removed, and the same problem still appears.

[Kapil Kapre]

Mike,
Thanks for following up. After testing it on our linux boxes this seems to be a weird configuration issue. Can you check that you have write priveleges to the project directory that you are trying to create the UMR into? Banning write access was the only way we could replicate the error ourside. Also is there anything special about the workspace we should know about (esp. filesystem) that might be useful?
Thanks,
– Kapil

[mansley]

Hi Kapil,

Thanks for this. My workspace directory was a two-level soft link. ~/workspace -> ~/src/workspace, and ~/src -> /mnt/src. /mnt/src is a separate mount point. I checked all the permissions and everything was correct. Then I removed the ~/workspace link and created a clean ~/workspace directory, and started eclipse and used that as a fresh workspace in a simple directory structure. I created a new test project, and tried to create a repository, and received the same error.

I will keep trying to see what else I can find.

Cheers…

Mike

hi,
I also have problems.
yesterday I did some tests with UML.
then I finished my work with File–>Exit
(all files are saved, but uml model still opened in editor)
hitting the exit menu caused a crash of eclipse
then tried to restart eclipse, but the whole workspace was damaged
restarted the machine (W2K)
renamed the myeclipse linkfile into .tmp
restarted eclipse with -clean
renamed the myeclipse back
restarted eclipse again
nogo with this workspace
looking into the logfile

hey this is the first time a plugin vendor crashed a whole workspace.
I have to create a new one and import the projects

but for the moment I go back to exadel studio. there’s no uml,
but also no crash 😉 and: they have facelets

wish you a happy new year – I’ll try myeclipse again in 2-3 months with
new release
regards

Was the editor hung or was it working prior to you exiting from eclipse?

The UML plugin doesnt really interact with the workspace as such. So I’m not sure if UML caused the crash. Thats also not to rule out that it could have caused in your case. Did you simply open a UMR and eclipse crashed on exit which also corrupted your workspace? Any further feedback would be appreciated.

Same UI situation and error in the log file.

!MESSAGE Exception in com.genuitec.eclipse.uml.wizard.NewUMLModelFileWizardPage.getNewFile(): java.lang.NoClassDefFoundError

I’m running eclipse on WinXP as an administrator; I tried a fresh install of eclipse 3.1.1 and last stable and milestone releases of MyEclipse.

One other strange thing happened to eclipse, but I don’t know whether it relates to this: any time I try to look for updates, I get UnknownHostException on every update URL.
