commit 479e9ae259028f3855fdae7de9de95ec937feb61 Author: 虎鸣 <[email protected]> AuthorDate: Tue Jun 16 12:09:51 2026 +0800 build: remove Scala 2-only compiler options from Scala 3 projects Motivation: All sample projects use Scala 3.3.7 but several still include Scala 2 compiler options (-Xlog-reflective-calls, -Xlint, -Ywarn-unused:imports) that produce "bad option" warnings or are silently ignored. Modification: Remove -Xlog-reflective-calls, -Xlint (without arguments), and -Ywarn-unused:imports from scalacOptions in 10 sample build.sbt files. Keep -deprecation, -feature, -unchecked which are valid in both Scala 2 and 3. Result: Clean compilation without "bad option" warnings in all affected samples. --- pekko-sample-cluster-client-grpc-scala/build.sbt | 4 +--- pekko-sample-cluster-docker-compose-java/build.sbt | 3 +-- pekko-sample-cluster-docker-compose-scala/build.sbt | 3 +-- pekko-sample-cluster-java/build.sbt | 2 +- pekko-sample-cluster-scala/build.sbt | 2 +- pekko-sample-distributed-data-java/build.sbt | 2 +- pekko-sample-distributed-data-scala/build.sbt | 2 +- pekko-sample-kafka-to-sharding-scala/build.sbt | 4 +--- pekko-sample-persistence-scala/build.sbt | 2 +- pekko-sample-sharding-scala/build.sbt | 2 -- 10 files changed, 9 insertions(+), 17 deletions(-) diff --git a/pekko-sample-cluster-client-grpc-scala/build.sbt b/pekko-sample-cluster-client-grpc-scala/build.sbt index ac15013..00a5a2b 100644 --- a/pekko-sample-cluster-client-grpc-scala/build.sbt +++ b/pekko-sample-cluster-client-grpc-scala/build.sbt @@ -14,9 +14,7 @@ lazy val `pekko-sample-cluster-client-grpc-scala` = project Compile / scalacOptions ++= Seq( "-deprecation", "-feature", -
