eclipse creates long pathnames [message #1800944]

Hi,

In our DTAP environment we have several apps that use Eclipse.
Now, we notice that Eclipse can create very long pathnames.

i.e:

C:\users\jja119.PROD.V2\.eclipse\com.ibm.mq.explorer.ui.rcp.RcpApplication_9.0.0.201605122106_171862051_win32_win32_x86_64\p2\org.eclipse.equinox.p2.engine\profileRegistry\profile.profile\.data\.settings\org.eclipse.equinox.p2.artifact.repository.prefs

This can create a problem with roaming profiles being synchronized to the Profile Server.
We enabled Long Paths in Windows. Registry: LongPathEnabled=1
But, even then , the maximum is around 30.000 characters.

I had a user who had folders in the .eclipse folder that went 10.000 ! folders deep.

Could it be related to the scripts our testers use, or is there something I can configure to prevent this from happening?

Thanks and regards,

Peter

That looks very anomalous to me. I have hundreds of Eclipse installations and they never produce such deep folders. Even these o.ide.* folder segments you show in the JPG don't look like something I'd ever expect to see in an Eclipse installation...

In this case IBM MQ Explorer was the actual program that created these folders.
In some cases, these long pathnames are created.
I somewhere read it could be with crashing scripts that causes eclipse to be stuck in some kind of loop, creating copies of the same folder into a new folder with the same name.

(in this case 0.ide.13.0.0.1.42.170225.201\0.ide.13.0.0.1.42.170225.201\0.ide.13.0.0.1.42.170225.201\0.ide.13.0.0.1.42.170225.201 and so on)

I also have seen this behaviour when using SQL Developer.
