However, it is likely that many of those tasks will have been run with exactly the same inputs in a prior CI build, populating the build cache; the outputs from those prior runs can safely be reused, resulting in dramatic build performance improvements.

*Precompiled Script Plugins* are Kotlin or Groovy DSL scripts compiled into Java class files packaged in a library.
They offer better performance and maintainability compared to script plugins, and they can be reused across different projects.
You can also write them in Groovy DSL but that is not recommended.

*Binary Plugins* are full-fledged plugins written in Java, Groovy, or Kotlin, compiled into JAR files, and published to a repository.
