ASF GitHub Bot commented on MNG-6869: ------------------------------------- mthmulders opened a new pull request, #995: URL: https://github.com/apache/maven/pull/995 This pull request adds a few basic checks that users can run to see if they've installed Maven correctly. This includes: 1. A check if the local Maven repository is usable. 2. A check if Maven can connect to remote repositories configured in **settings.xml**. 3. A check if Maven can resolve a pre-existing artifact (to be precise, `org.apache.maven:apache-maven:3.8.6`). These checks honour **settings.xml** profile activation through `<activeProfiles>`. The artifact resolution check honours any configured mirrors. The connection check is quite rudimentary, and only functions at the HTTP connection level. Since there is no guarantee that a repository will contain a particular artifact, there's not much more we can do. The artifact resolution check is a bit more thorough: it checks if there is _any_ way in which Maven can resolve itself. It does so by temporarily using a "dummy" local repository. This is necessary to prevent a "false positive", where the artifact may have existed before. We have not added unit tests or integration tests (yet). At some level, they may be useful, but we expect a full integration test to be a significant amount of work that would not provide a lot of value. We're curious to hear your opinions about that trade-off. --- Following this checklist to help us incorporate your contribution quickly and easily: - [X] Make sure there is a [JIRA issue](https://issues.apache.org/jira/browse/MNG) filed for the change (usually before you start working on it). Trivial changes like typos do not require a JIRA issue. Your pull request should address just this issue, without pulling in other changes. --> [MNG-6869](https://issues.apache.org/jira/browse/MNG-6869) - [ ] Each commit in the pull request should have a meaningful subject line and body. - [X] Format the pull request title like `[MNG-XXX] SUMMARY`, where you replace `MNG-XXX` and `SUMMARY` with the appropriate JIRA issue. - [ ] Also format the first line of the commit message like `[MNG-XXX] SUMMARY`. Best practice is to use the JIRA issue title in both the pull request title and in the first line of the commit message. - [X] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [X] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will be performed on your pull request automatically. - [X] You have run the [Core IT][core-its] successfully.
