[mylyn-integrators] Problem with local update sitt after updating plugin

[Ivan <mungoparks@xxxxxx>]

Hello,

I have a plugin that uses mylyn api that was initiali written on eclipse 3.3
ant that i have now ported to run on eclipse 3.4.
The changes were all mylyn changes that resulted from the mylyn change
from 2.3 to 3.0.

When i run the plugin from inside the IDE everything works fine and
building the plugin also works normal.
When i try to instll the plugin with a local update site all
dependencies are resolved correctly
but the plugin is not installed because i face this error :

An error occurred while collecting items to be installed
Error closing the output stream for
com.papic.mundvi.agent/org.eclipse.update.feature/1.5.0 on repository
file:/home/ivan/Entwicklung/IDE/Eclipse/EclipseGanymede/rcp/eclipse/.
Error unzipping /tmp/com.papic.mundvi.agent_1.5.031400.jar: Invalid zip
file format

When i open the jar files inside the locale update site they all are fine
but the one under /tmp/com.papic.mundvi.agent_1.5.031400.jar is not

I know that this is not a mylyn problem but still i hope to get some information here
that help me to solve this problem

Thanks
Ivan
