SBT doesn't seem to be cached completely

Description:

Every of my CI runs contains the below lines of logs:

Run sbt compile

...

It seems to compile the source code from sbt plugins every time. I wonder if there's a bug with sbt caching i.e. we aren't caching everything.

Task version:

actions/setup-java@v4

Platform:

• Ubuntu

Runner type:

• Hosted

Repro steps:

Our project/plugins.sbt looks like below:

lazy val root = Project("plugins", file("."))
  .aggregate(SbtSvelte, SbtI18n, sbtPostcss)
  .dependsOn(SbtSvelte, SbtI18n, sbtPostcss)
lazy val SbtSvelte = RootProject(uri("https://github.com/tanin47/sbt-svelte.git#f1e844b12a1985562f8c6e1022c824af56ddd37f"))
lazy val SbtI18n = RootProject(uri("https://github.com/GIVESocialMovement/sbt-i18n.git#e55ecf1d1858c4be87a7b34984aea5982b974e70"))
lazy val sbtPostcss = RootProject(uri("https://github.com/tanin47/sbt-postcss.git#bec39d2c65b449636cab87152859a08415f5ff52"))

Expected behavior:

We shoudn't recompile the source code of these sbt plugins every time.

Actual behavior:

It recompiles the code and takes an extra 15 seconds.

Thank you.
