Mylyn disappears after installing 3.3.1 [message #505682]

Hi,

after an automatic update from Mylyn 3.3.0 to 3.3.1 on a Eclipse 3.4 all Mylyn views and buttons disappears. There was also no Mylyn brunch in the Preferences dialog anymore.

After uninstalling the update coming back to Mylyn 3.3.0 all works well again.

Any hints where it can come from?

What I had encountered last year (December 2009) before this happens is that several attempts to update to a new Mylyn version (don't remember which one but I guess 3.3.1) had failed.

Regards, Denis

Denis, can you provide additional detail which platform and Eclipse
distribution you are using? Can you provide steps to reproduce the problem?
Is Mylyn still listed under Help > About after the update? What is the
output if you start "eclipse -console" and type "ss mylyn"?

Note that there are known problems with shared installations that can cause
features to disappear when updating features that are part of the platform:

Steffen,

the Eclipse Platform is
Version: 3.4.2
Build id: M20090211-1700.

Mylyn was still listed under Help>About.

For reproducing: I had simply follow the automatic update procedure...

After the problem appears I had done a uninstall for this mylyn version. Unfortunately I have no time to reinstall it now for reproducing it; may be later.

I took a look into the log file and it contains a lot of problems like the following one but from different mylyn packages:

Here comes some more information. The log lists the following mylyn package files as being not accessible:

I took a look into the plugin folder -- these files are not available. Other Mylyn package files with version 3.3.1 are available.

So it can be a download problem also; but also a packaging problem...

Thanks. That sounds like the plug-ins that ended up on disk got corrupted
somehow in the install process. I have tried installing Mylyn 3.3 into
Eclipse 3.4.2 and did not experience any problems updating to 3.3.1.

Let me know if you have any more clues as to what may have caused the errors
you were seeing.

Seems it was an download problem. After next automatic Mylyn update it worked well.

Sorry having brothered you. But it was not easy to recognize for me that this was a download problem since the update had failed several times and there was no hit or error message that the download had failed.

Thanks and regards, Denis
