Reassigned for further evaluation.

What build are you using? You filed it against 8.0.2 but this error is an assert, it should not happen in a release.

Is this the folder you cloned into? /home/tomas/work/4finance/workspaces/2/loans_test/loans
Did you play with it before the clone, e.g. was it already existing clone, you deleted it and cloned again?

Product Version: NetBeans IDE 8.0.2 (Build 201411181905)
Updates: NetBeans IDE is updated to version NetBeans 8.0.2 Patch 2
Java: 1.8.0_40; Java HotSpot(TM) 64-Bit Server VM 25.40-b25
Runtime: Java(TM) SE Runtime Environment 1.8.0_40-b26
System: Linux version 4.1.6-200.fc22.x86_64 running on amd64; UTF-8; cs_CZ (nb)


The directory was new, empty, ununsed directory.

Is it reproducible? Does it always happen?

yes, it is reprocudible - it happens always. I'm not able to check out a project.

I am adding some more logging to catch the root cause for this. Could you please try a dev build (you will be notified here in the issue with a comment with a link to download the dev build in few days) with my additional logging and when it happens, could you then attach the full IDE log with the error?

fix: http://hg.netbeans.org/core-main/rev/6458d9d84d89

yes, I can. I'll try it with dev build. I'm waiting for dev build and comment in this issue.

Integrated into 'main-silver', will be available in build *201509120002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: #255159 - Cannot clone git repo on Linux
Add more logging.

Tested on 201509130002.

I've tried to clone repo into different locations and it looks like it depends on the destination path - a long path does not work (/home/tomas/work/4finance/workspaces/2/loans_test/loans), a short one works fine (/home/tomas/testLoans). The same experiance for 8.0.2 version as well as for dev version.

Here is the log from dev version:

I am sorry but the exception you submitted in the last comment comes from 8.0.2 sources, the lines and the exception does not correspond to latest NetBeans dev sources.
Can you please try once again with the dev build - ideally start it with a fresh userdir: netbeans --userdir /tmp/userdir255159
When it starts do not import any plugins, do not install any updates, just try to do the clone and attach the IDE log when you get the exception.
Thanks.

.. and please attach the full log, not just a snippet, whole file as an attachment with

Created attachment 156182 [details]
log with exception in git clone

I need to start netbeans with long path to userdir, otherwise exception is not thrown (/opt/netbeans-dev-201509130002/bin/netbeans --userdir /home/tomas/work/4finance/workspaces/5).

Aaah, i get it now. You're cloning into NetBeans userdir.
--userdir /home/tomas/work/4finance/workspaces/5 specifies a NB userdir, that is not a workspace, it is a folder with NetBeans metadata, not meant for user to keep his data in. You should clone anywhere but in there.
I'll try to get rid of the exception.

I see. Thanks for solution and fix.
