How to use authentication with target platforms

[guw]

As per guide on the wiki:
https://wiki.eclipse.org/Tycho/Target_Platform/Authentication_and_Mirrors

I created <server> entries with the <id> being the full URL without trailing slash.

However, the build is still failing with:

[ERROR] Failed to resolve target definition ...: Failed to load p2 metadata repository from location <url>: Unable to read repository at: <url>/site.xml. Login canceled by user. -> [Help 1]

Any ideas?

Full stacktrace is:

Caused by: org.eclipse.equinox.p2.core.ProvisionException: Unable to read repository at: <url>/site.xml. Login canceled by user.

Can you give more details? e.g. what Tycho version is used? From the stack trace it seems your are using a nested target, it might be that authentication is not fully supported there.

We have an integration test for authentication here (java code) so if you could provide an integration-test to demonstrate the issue that would be great.

[laeubi]

What version of Tycho do you use, can you try out the current tycho snapshot build (4.0.0-SNAPSHOT)

[peterkir]

Same behaviour - AuthenticationFailedException

[peterkir]

I was using 3.0.4 previously.

[laeubi]

4.0.0 was recently released, you should upgrade to Tycho 4, if the problem persist it would be good to share an example to show the problem.

[peterkir]

Thx for the support. I will try to create an example.
