Installer win64 was executed on Windows 10 behind a company firewall.

Pressing the "Update" button shows an authentication dialog, but providing user and password for the default company proxy (that is unfortunately the wrong one) does not help.

The proxy settings cannot be changed in the dialog.
Is there a possibility to provide an alternative proxy ?

Best regards
Harald

The NPE itself should be fixed by the commit in this Bugzilla:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=540459

It's not clear if that really fixes the problem though...

The comment in this Bugzilla describes someone else's experiences with this problem and what they did to fix/workaround it.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=541465#c11

I've not been able to reproduce the problem in order to really fix it. :-(

In any case, you could try the unrestricted installer available at the following location:

https://wiki.eclipse.org/Eclipse_Installer

It is the latest one and contains the fix for the NPE and, unlike the installers available from

https://www.eclipse.org/downloads/

it can install any version of Eclipse, not just Eclipse 2018-12...

I would appreciate your feedback on how this works out for you.

Hi Ed,
thank you for the detailed feedback.

The unrestricted installer did the job !
I downloaded the latest nightly build of the installer and was able to start the exe file without NullPointerException.
After setting an alternative proxy in the advanced mode I was able to start the installation.

In the P2 part another problem occurred: The installer failed to access some of the repositories.
We are running behind an NTLM authenticating proxy and the company recommendation for eclipse is:
-Djava.net.preferIPv4Stack=true
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4
With that extension in the ini file of the installer the complete setup worked perfectly :-)

Thanks!

Harald
