Couldn't delete Temp dirs after running Creating Artifact

littletaffer

Hi there,

While debugging the create artifact function, I noticed that two of these lines appeared in DeploymentMenu version 5.9:

tempbarFolder.delete(true, null);
tempclassesFolder.delete(true, null);‍‍

These two lines are not in 5.8 - as it is used as the base for our work on customizing the RCP.

I added that two lines above below the "deployment.refreshLocal". It causes a ResourceException error like:

org.eclipse.core.internal.resources.ResourceException: Problems encountered while deleting resources.

Interestingly, this problem doesn't occur when running in the Apple OS platform.

I remembered reading a past post that the two lines added above was based on a suggestion to clean off temp folders. In Windows presently we can't remove those. Could it be due to different resource handling or it might be an unexpected bug?

Did I miss out something in the designer code related to this func or do I have to turn off some setting at the machine / OS level?

It looks like there's a bug inside the zipDirectory function. The FileInputStream and the ZipOutputStream instance was not closed. This gives error in Windows platform.

The ZipOutputStream is closed in the finally statement. The FileInputStream wasn't closed, I committed a fix for that.
If it still doesn't work with version 5.9.3 (which I'll release tomorrow), please create a JIRA.

Best regards,

Hi Tijs,

The code works fine. From my side, I have also added the out.close() after the out.closeEntry() as an extra measure in case. It would be better to add that one line in there.
