また、次のように突然終了することもあります。
sbt appears to be exiting abnormally.
The log file for this session is at /var/folders/vf/3khb58091wd0_1rz1yh6knb00000gp/T/sbt3242766352271599341.log
Java.lang.OutOfMemoryError: PermGen space
Error during sbt execution: Java.lang.OutOfMemoryError: PermGen space
解決策はありますか?
これは、巨大なコードベースをコンパイルする場合に時々起こります-多くのクラスがVM実行中のsbtにロードされます。
SbtのPermGen
スペースを増やす必要があります。フラグ-XX:MaxPermSize=256m
を使用します。256
は、永久世代の希望のサイズに変更できます。
実行:
cat `which sbt`
sbt起動スクリプトを見つけます。次に、それを編集して、sbtランチャーを同様の方法で実行するJava
コマンドでフラグを含めます ここで説明-Xmx
および-Xms
。
-XX:+CMSClassUnloadingEnabled
フラグを追加すると、sbtは、使用されなくなった以前のコンパイル実行のクラスでクラスローダーをアンロードできるようになります。
編集:
または、 sbtを実行するための拡張スクリプト を使用している場合は、SBT_OPTS
環境変数でこれらのオプションを設定できます。
