ここで既存の回答に追加するだけで、
Play 2.2x から Play 2.3.x にアップグレードした後も、この動作が見られます ( MigrationGuideを参照) 。
以下のようにデバッグしていました。
Linux では、プロジェクト フォルダーに移動してから、次の操作を行います。
$ bash -x `which sbt`
.... OUTPUT SKIPPED....
++ (( 128 < 512 ))
++ local 'common_opts=-Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m'
++ [[ 1.7.0_55 < 1.8 ]]
++ local perm=256
++ echo '-Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m'
+ execRunner java -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
+ [[ -n '' ]]
+ [[ -n '' ]]
+ java -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
最後の行のコマンドを書き留め、現在のプロセスをキャンセルし、オプションをCtrl+C
追加して実行します:-verbose
java
java -verbose -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
最後に も追加logLevel := Level.Debug
しましたproject/plugins.sbt
。
ただし、次のような出力を出し続けます。

ダウンロードする jar が多すぎるようです。現在、Typesafe Activator のオフライン バージョン (356 MB のダウンロードはこちら) を使用していますが、これは非常に高速です!
