The current connection URL is invalid, and doesn't specify a proper tool:

  connection.set("scm:https://[email protected]/IntellectualSites/FastAsyncWorldEdit.git")

• FastAsyncWorldEdit/buildSrc/src/main/kotlin/LibsConfig.kt

  Line 244 in 2f309ff

  connection.set("scm:https://[email protected]/IntellectualSites/FastAsyncWorldEdit.git")

scm:git:https://github.com/IntellectualSites/FastAsyncWorldEdit.git would be a valid example, including "git" as the SCM tool.
