Hi everyone, I'm currently setting up the environment for a legacy code base.

I'm trying to install Xtext 2.7.3 for Eclipse RCP Indigo SR2, but I keep running into issues with missing required items and a repository that can't be found.

The error message I'm receiving when trying to install the Xtext Complete SDK 2.7.3.v201411190455 (org.eclipse.xtext.sdk.feature.group 2.7.3.v201411190455) is:

"Cannot complete the install because one or more required items could not be found. Software being installed: Xtext Complete SDK 2.7.3.v201411190455 (org.eclipse.xtext.sdk.feature.group 2.7.3.v201411190455) Missing requirement: JUnit Testing Framework 4.12.0.v201504281640 (org.junit 4.12.0.v201504281640) requires 'bundle org.hamcrest.core 1.3.0' but it could not be found Missing requirement: JUnit 4.13.2.v20211018-1956 (org.junit 4.13.2.v20211018-1956) requires 'bundle org.hamcrest.core 1.3.0' but it could not be found Cannot satisfy dependency: From: Xtext Junit4 Support 2.7.3.v201411190455 (org.eclipse.xtext.junit4 2.7.3.v201411190455) To: package org.junit.internal 4.10.0 Cannot satisfy dependency: From: Xtext Complete SDK 2.7.3.v201411190455 (org.eclipse.xtext.sdk.feature.group 2.7.3.v201411190455) To: org.eclipse.xtext.junit4 [2.7.3.v201411190455]"

Additionally, I get an error message saying "No repository found at http://download.eclipse.org/eclipse/updates/3.7/categories." and "No repository found at http://download.eclipse.org/technology/epp/packages/indigo/." while the install new software menu is loading.

I've tried several things, including checking my internet connection, restarting Eclipse, and using a different computer, but the problem persists.

I'm hoping someone in the community has experience with this issue and can offer some advice or assistance. Has anyone else encountered this error and found a way to fix it? Any help would be greatly appreciated!

Thank you.

You can use this to find repositories containing specific things:

https://wiki.eclipse.org/Eclipse_Oomph_Authoring#How_to_find_a_P2_repository_at_Eclipse_using_the_Repository_Explorer

You can use this to browser what's available on the download server:

https://download.eclipse.org/justj/?file=

Sometimes really old things get moved to archive.eclipse.org but the download.eclipse.org server should still serve them as if they were located on that server:

https://archive.eclipse.org/justj/?file=

E.g., I would expect http://download.eclipse.org/technology/epp/packages/indigo/ to work because it exists here:

https://archive.eclipse.org/technology/epp/packages/indigo/
