The indentation of this exclude line has increased from 8 spaces to 10 spaces. For consistency with other elements in the Seq (e.g., lines 962-963 and 967-968, which are indented by 8 spaces), this line should also be indented by 8 spaces.

More importantly, an ExclusionRule like exclude("junit", "junit") placed directly as an item in the libraryDependencies sequence is unlikely to have the desired effect of excluding a transitive dependency.
To exclude junit from a specific dependency (e.g., fluency-treasuredata), the syntax would typically be:

"org.komamitsu" % "fluency-treasuredata" % FLUENCY_VERSION exclude("junit", "junit")

Or, for a project-level exclusion (if this fluentd project is defined with .settings(...)):

excludeDependencies += ExclusionRule("junit", "junit")

Please verify:

1. If this exclusion is still necessary. The comment on line 964 refers to a CVE related to junit as a transitive dependency via td-client-java -> json-simple. A quick check suggests junit might not be a transitive dependency of org.komamitsu:fluency-treasuredata:2.7.3 through this path with current versions.
2. If the exclusion is necessary, it should be applied using the correct sbt syntax to ensure it's effective.

The current form is likely non-functional and could lead to confusion or a false sense of security regarding the CVE mentioned.
