Trying to get a new one.` for every repository in every iteration.\r\n\r\nAfter looking at the code, I'm not sure how the caching should work when the `scopeForInstallationId(...)` returns a new `GitHubClient` instance so I assume the hash map with the installation tokens will be empty.\r\n\r\nI'm not very good with java so my assumption is I'm doing something wrong, can you give me some pointers?","author":{"url":"https://github.com/bbaga","@type":"Person","name":"bbaga"},"datePublished":"2021-04-15T09:17:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/57/github-java-client/issues/57"}
