This can be?

Suggested change

	eclipse().withP2Mirrors(['https://download.eclipse.org/eclipse/updates/4.29/':'https://ftp.osuosl.org/pub/eclipse/eclipse/updates/4.29/']).configFile rootProject.file('buildSrc/formatterConfig.xml')
	eclipse().withP2Mirrors(Map.of("https://download.eclipse.org/eclipse/updates/4.29/", "https://ftp.osuosl.org/pub/eclipse/eclipse/updates/4.29/")).configFile rootProject.file('buildSrc/formatterConfig.xml')

[prudhvigodithi]

Initially we use Map.of (#17172) which works, but just following the instructions in https://github.com/diffplug/spotless/blob/main/plugin-gradle/README.md#eclipse-jdt

[owaiskazi19]

@prudhvigodithi Map worked too https://github.com/opensearch-project/neural-search/pull/1540/files.
Nvm, I see mirrors are completely removed

I believe this is not new issue [1], has been surfacing since spotless 7.0.0 release (if I am not mistaken), probably the best option is to downgrade spotless to 6.x

I'm still seeing:

[cwperks]

@prudhvigodithi do we potentially need to add this to other branches?

[prudhvigodithi]

I'm thinking to completely remove withP2Mirrors and allow eclipse() to default use https://download.eclipse.org/. As seeing the instructions the mirrors https://github.com/diffplug/spotless/blob/main/plugin-gradle/README.md#eclipse-jdt are only for restricted scenarios and also withP2Mirrors setting defaults to mirror. It would be nice if there is a setting 1st it would try https://download.eclipse.org/ and then fallback to mirror.

[prudhvigodithi]

@prudhvigodithi do we potentially need to add this to other branches?

Yes @cwperks we need to backport to the relevant branches , IMO we need to force merge and backport as the configured mirror is completely down https://mirror.umd.edu/eclipse/eclipse/updates/4.29.

Overriding and merging on this PR as the build is expected to fail until its backported:

The backport to 2.18 failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-2.18 2.18
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-2.18
# Create a new branch
git switch --create backport/backport-19199-to-2.18
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 4fc44d10caa18c9280cf5ad8377dc1f1cdfa4599
# Push it to GitHub
git push --set-upstream origin backport/backport-19199-to-2.18
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-2.18

Then, create a pull request where the base branch is 2.18 and the compare/head branch is backport/backport-19199-to-2.18.

#19199 (comment) we dont need to backport to 2.18 as I dont see the mirrors added to 2.18 https://github.com/opensearch-project/OpenSearch/blob/2.18/gradle/formatting.gradle#L85.
