Hello all

in case I create simple xtext project with maven as based builder and try to build. The following error is observed.

[ERROR] Failed to resolve target definition C:\Users\agorlov\Documents\projects\workspaces\flexprod\atom\dev_6.400.00_FXPST_27656\implementaion\com.psl.atom.target\com.psl.atom.target.target: Failed to load p2 metadata repository from location http://download.eclipse.org/releases/2019-03: Unable to read repository at http://download.eclipse.org/releases/2019-03. Unable to connect to repository https://download.eclipse.org/technology/epp/packages/2019-03/content.xml: Connection timed out: connect -> [Help 1]

In case I changed
<repository location="http://download.eclipse.org/releases/2019-03/" />

to

<repository location="http://download.eclipse.org/releases/2019-03/201903201000" />

The error is disappeared. Is it correct correction?

http://download.eclipse.org/releases/2019-03/ is the correct location.
it may always be that eclipse servers have a bad day.
(you should open a bugzilla if problem persists for a longer day)

http://download.eclipse.org/releases/2019-03/201903201000
is also correct but does not include the stuff from the epp packages update site

I cannot find it on http://download.eclipse.org/modeling/tmf/xtext/updates/orbit/2019-03

Could you help me?

I try to open the site via "Install new software" feature and enter pattern junit

also make sure that you use a otbit update site that matches stuff.
you can find many releases here
https://download.eclipse.org/tools/orbit/downloads/
and they all contain different versions for different eclipse versions

https://download.eclipse.org/modeling/tmf/xtext/updates/orbit/2019-03/compositeContent.xml
forwards to
https://download.eclipse.org/tools/orbit/downloads/drops/R20190226160451/repository/
(see https://download.eclipse.org/tools/orbit/downloads/drops/R20190226160451/ for a list of contents)

there is no 5.3.1

Note that you can use the Repository Explorer to find an Eclipse-hosted update site for a specific installable unit version:

Always, I use a simple project after migration to a new version of eclipse and XText for smoke testing. All links to repositories are generated or saved by XText. Maybe my eclipse distribution is not up to date.

In any case, thank you for support
