As of this morning our gradle builds using the spring boot plugin 2.6.1 started failing due to this dependency going missing from maven central.

SpringBoot org.toml:tomlj:1.0.0 no longer resolving from maven central

Comment From: wilkinsona

It's still there as far as I can tell: https://repo.maven.apache.org/maven2/org/tomlj/tomlj/1.0.0/. I suspect you are suffering a problem specific to your environment as our CI builds are also working. Also, please note that in tomlj/tomlj#34 you have linked to a search with the wrong group (org.toml rather than org.tomlj). A search for org.tomlj shows the expected artifact: https://search.maven.org/search?q=org.tomlj.

We also started experiencing the same issue a few hours ago. Getting the following error when building without using the cached version:

[17:04:48] #19 15.73 > Could not determine artifacts for org.tomlj:tomlj:1.0.0: Skipped due to earlier error

Using org.springframework.boot:org.springframework.boot.gradle.plugin:2.5.3

Without knowing what the earlier error was, I can't really help any further. I still suspect a problem with your access to Maven Central. Our local and CI builds have been able to resolve tomlj without any problems. See this build scan, for example.

If you've eliminated your network as a possible cause, you may want to open an MVNCENTRAL issue. Maven Central uses a CDN so it's possible that the problem is location-specific.

Depending on the earlier error, this may also be due to a problem with Gradle's plugin portal. There's some discussion about it and a possible workaround in their community Slack. The problem's being tracked on status.gradle.com.
