I believe I am posting this question in the right place.

I was doing some changes in JDT core components and was building, testing, packaging successfully.

From yesterday onwards (12th November 2020), I came across the following error. The Tycho plugin throws this error when I try to (mvn)package JDT Core component.

[ERROR] Failed to execute goal org.eclipse.tycho.extras:tycho-eclipserun-plugin:2.1.0-SNAPSHOT:eclipse-run (default) on project org.eclipse.jdt.core: Execution default of goal org.eclipse.tycho.extras:tycho-eclipserun-plugin:2.1.0-SNAPSHOT:eclipse-run failed: Some required artifacts could not be downloaded. See log output for details.

[INFO] --- tycho-eclipserun-plugin:2.1.0-SNAPSHOT:eclipse-run (default) @ org.eclipse.jdt.core ---
[ERROR] The following artifacts could not be downloaded: 
[ERROR]   osgi.bundle,org.eclipse.jdt.core,3.24.0.v20201112-0918
[ERROR]   osgi.bundle,org.eclipse.pde.api.tools,1.2.100.v20201112-0408
[ERROR]   osgi.bundle,org.eclipse.pde.core,3.14.100.v20201112-0616

The way I build (mvn package) the projects is through the command "mvn -P build-individual-bundles package -o". I used the
Oomph installer to create a development environment and then use the command ("mvn -P build-individual-bundles package -o") to build the project after doing the modifications.

I believe this error is a fundamental error. Since I am new to JDT Core developments, I can not figure out the RCA. Does anybody have an idea about this error?
